Sacoolas, an American citizen, claimed diplomatic immunity after the teenager died
in a collision with her car almost two years ago.
Speaking at the G7, Johnson said the president was
"extremely sympathetic" and "actively engaged" in the case.
The confirmation of talks comes after Biden's predecessor Donald Trump refused
to intervene.
Crucially, it will raise hopes for the Dunn family that Ms
Sacoolas could still be stripped of diplomatic immunity in order to face a
British court over the death.
The prime minister says his counterpart has his “own personal
reasons for feeling very deeply about the issue”.
Biden lost his first wife, Neilia Hunter, and their
one-year-old daughter Naomi in a car crash in 1972.
A major police probe has started after a baby girl was found unresponsive in a garden pound in Falkirk last night.

It's understood the 18-month-old girl was pulled from the water before medics arrived and was then rushed to Forth Valley Royal Hospital under a police escort.
One neighbour, who didn't want to be named, told the Record: "I was cutting the grass and then all I heard was screaming.
"I could tell by the screaming there was something seriously wrong, it was horrible, I can still hear it in my head.

"Paramedics carried the child out into the ambulance and it went flying out the street behind a police car."
A Police Scotland spokesperson said: “Emergencies services attended at Dollar Avenue in Falkirk at 6.10pm on Thursday, 10 June, after an 18-month old child had fallen into a pond.
"The child was taken to Forth Valley Royal Hospital for treatment, where she died a short time later. Enquiries into the incident are ongoing.”
The health secretary's account of the government's early handling of the crisis in care homes is now widely disputed by many of those who witnessed it first-hand.
Matt Hancock appeared before MPs to answer questions about the UK government's handling of the pandemic.
The session was part of a joint inquiry by the Health and Social Care and Science and Technology Committees, which are considering what lessons can be learned from the government's response.
And listening to every word was Lyndsay Allison, whose 76-year-old father-in-law, John, died of COVID shortly after being discharged from hospital into a care home last May.

She said: "The health secretary said that his main aim was to protect and shield the elderly and the vulnerable. I think what he meant by that was protect the NHS.

"Because care didn't get protected. We've not had any apology and Matt Hancock refuses to admit any fault whatsoever.
"It's been a year since John's death. This cloud hanging over us doesn't allow us to grieve properly. It doesn't allow us to make sense of anything that's happened.

"I understand it was the beginning of the pandemic and mistakes were made, but those mistakes need admitting to so everybody can move forward and learn from those mistakes.

At the beginning of the pandemic, many care homes struggled to prevent the spread of COVID-19. This was either because personal protective equipment (PPE) supplies were scarce or because thousands of hospital patients were sent to care homes without a COVID test.
But Mr Hancock told the committee that untested discharges contributed to just 1.6% of care home deaths, instead claiming staff might have brought the virus in from the community.
"Sadly, the biggest route of COVID-19 is through the community, it's through people who live in the community and work in the care home," he said.
That has angered people like Pearl Jackson, who runs 21 homes across England and has been in care business for nearly 40 years.
"Our experience on the ground is very different," she said. "It was clear it (the COVID infection route) was from hospital and the pressure we were under at that timeto take untested discharges was immense.

"I had senior members of staff within hospitals forcing me to take patients without tests. And it seemed to me that the priority was to discharge elderly without tests because they couldn't wait three or four days for a test to come back. They wanted to clear hospital beds as quickly as possible.
"There seems to be a projection of blame on to care homes and that's not justified. We had one person discharged from hospital. Until that moment, we were negative throughout. Within a week 15 residents had COVID.
"I was enraged watching the health secretary. If he came clean and apologised, we would support him. We've tried our best to recover. But he still hides behind blame."
This strength of feeling is shared by another care provider.

Nicola Richards, managing director at Palms Row Healthcare, witnessed for herself how quickly COVID took over her Sheffield-based care home.
In early March she was warning of a lack of PPE and testing as the pandemic developed.
She told Sky News: "There was a lack of PPE supplies diverted from care homes, so how could homes manage safely with limited supplies.
"Listen to all care providers. We are all saying the same thing. It's not a political debate - people lost their lives unnecessarily.
"I am angry that Mr Hancock said the government tried to protect care homes. They failed our elderly, their loved ones and our staff.
"He simply cannot be allowed to blame staff for spreading the virus. There should have been measures in place to protect them. They put their own lives at risk to care for others. They need to recognise that."
A hotel housing security staff and media for the G7 summit in Cornwall is to shut completely following an outbreak of COVID-19.
The Pedn Olva hotel in St Ives - the host town for the summitof world leaders and just one mile from Carbis Bay - said it would "fully close" after discussing the outbreak with Public Health England.
It's understood 13 staff are infected out of around 17 workers.
There were just 45 cases of COVID-19 in Cornwall in the week between 30 May and 5 June.

One staff member, who was leaving the hotel to self-isolate carrying two packs of COVID tests, told Sky News the hotel was "closing and boarding up".

Sky News spoke to a number of security staff protecting the German G7 delegation who are staying at the hotel.
They said they had "been told nothing" but that they might end up buying a tent and sleeping on the beach.

Most hotels in the county are fully booked because of the summit.
A number of media crews - including CBS - are understood to have been staying at the hotel and operating a live presenting position from its roof.

In a statement, the hotel owners - St Austell Brewery - said: "We can confirm that a number of our team at the Pedn Olva, St Ives, have tested positive for COVID-19.
"We immediately notified Public Health England of these cases and have been working closely with them to ensure we follow all appropriate safety guidelines.
"Following extensive discussions over the last few days with PHE and Cornwall Council, we have taken the decision to fully close the hotel.
"We fully appreciate the inconvenience given the limited accommodation options available in the area at the moment but the safety and security of our team and guests is our upmost priority. The hotel will reopen once a full COVID-19 deep clean has taken place and we have the available staff to run it."
The outbreak comes on the eve of the start of the G7 summit, with thousands of police, delegates and media in the county.
UK Prime Minister Boris Johnson said that he and President Biden were in “complete harmony” over the need to uphold the Good Friday Agreement, after talks in Cornwall, England, on Thursday ahead of the G7 summit.
“There's a complete harmony on the need to keep going, find solutions and make sure we uphold the Belfast Good Friday Agreement,” Johnson said in a pool clip.
Johnson denied rumors that Biden had pressured him over the implementation of the Northern Ireland protocol, adding that the US, UK and European Union “have one thing we absolutely all want to do, and that is to uphold the Good Friday, the Belfast (Good Friday) Agreement and make sure we keep the balance of the peace process going.”
“And that's absolute common ground. And, you know, I'm optimistic that we can do that,” he added.
Johnson said that the pair had “renewed” the relationship between the UK and the US, and covered a “huge” range of subjects, including security, NATO and climate change. “It's fantastic. It's a breath of fresh air,” he added.
The Belfast Agreement, also known as the Good Friday Agreement, was signed in April 1998, restoring self-government to Northern Ireland, and setting the stage to create their own power-sharing government with a 108-member Assembly.
Matt Hancock has said he knew Dominic Cummings wanted him to be fired as health secretary last year.
Appearing before MPs, Mr Hancock accused the PM's former aide of briefing journalists against him.
He also rejected a string of accusations levelled at him by Mr Cummings about his handling of the Covid pandemic.
He insisted he had always had the "wholesome support" of Boris Johnson.
In his own appearance before MPs last month, Mr Cummings said he had repeatedly called on Mr Johnson to sack Mr Hancock.
The aide said Mr Hancock should have been fired for "15 to 20" different things, accusing him of lying to the PM on several occasions - something Mr Hancock has firmly denied.
Asked on Thursday whether he knew Mr Cummings had wanted him gone, Mr Hancock replied: "Yes, because he briefed the newspapers at the time."
He then added: "Somebody briefed the newspapers - I now have a better idea of who it was."
He said he had "no idea" why Mr Cummings appeared to have so much animosity towards him, but he took a swipe at Mr Johnson's former top aide, who left Downing Street in December after losing an internal power struggle.
"I think the best thing to say about this, and this will be corroborated by lots of people in government, the best thing to say, is that government has operated better in the past six months."
While Dominic Cummings tried to skewer Matt Hancock with attacks on his ability and competence, Hancock is trying to side-step any mention of the former adviser.
He is relying on the backing of the PM for cover and trying to diminish the impact of Cummings at the time.
Responding to Cummings' claim that the 100,000 a day testing target was "criminal", Hancock says he put himself "on the line" by setting it and on the advice of his team.
But the MPs questioning him want to know why others in government were so sceptical. Hancock is taking full responsibility for it.
"I've never been to business school" he says, under pressure to explain why he set the target.
But he insists it was the right decision to force Whitehall to ramp up capacity.
Mr Hancock also denied an accusation from Mr Cummings that he had blamed initial difficulties in buying protective equipment during the pandemic's first wave on Chancellor Rishi Sunak and NHS England chief Sir Simon Stevens.
Mr Hancock said this was "not a fair recollection of the situation," adding he had asked the chancellor to remove a price cap on buying kit, which Mr Sunak then "rapidly" agreed to do.
He said he could not "recall" whether Mark Sedwill, the UK's most senior civil servant at the time, launched an investigation into the matter - another claim by Mr Cummings.
He once again rejected Mr Cummings's claim that he had lied to the PM that hospital patients were being tested before being discharged into care homes.
He told MPs he had pledged patients "would be tested" once enough testing capacity had been developed - and had delivered on this promise.

The health secretary also defended the government's initial advice to care homes that Covid testing would not be required before they could receive patients from hospitals.
Adding that ministers had always "followed the clinical advice," he said that early on in the pandemic there were worries that testing asymptomatic people could provide "false assurance" due to incorrect negative results.
'Bitterly regrets'
He also added clinicians were worried about people picking up Covid in hospitals during the 4-day turnaround period to receive a laboratory test result.
However, Mr Hancock said he "bitterly regrets" not pushing back harder against initial scientific advice that Covid was unlikely to spread asymptomatically.
He said he had asked scientists in January to look into evidence from China that the virus could transmit in this way - but was told during a World Health Organization call this was "highly likely" to have been down to "translation issues".
He added he had an "instinct" the advice was wrong, but said it was hard to overturn this when "you don't have the evidence that you're right, and the scientific consensus is wrong".
Mr Hancock is giving evidence to the Commons health and science committees, as part of their joint inquiry into the government's handling of the pandemic.
The chair of the science committee, Greg Clark, said at the start of Thursday's session that they had asked Mr Cummings for documentary evidence to back up his allegations against Mr Hancock.
But he added that they had not yet received any, "nor any explanation" from Mr Cummings. Mr Hancock told the committee this was very "telling".
