My car(2002 TL S) has check engine. P1457 error code.

delear recommand check fuel tank after change canister, two way valve, solrenoid valve, Gas cap...
It also need more $220 to check.

If the ecu has a problem which occur check engine light, is there no problem with ECU and my car. It's working is good. There is no problem to drive as i think
Someone (who is same as me) said that after change the ecu, the check engine gone.

Other shop sell the used 2002 TL s ECU.

Do you fill the gas tank above the first click of the automatic shutoff?
If so= gas can get pushed into the charcoal cannister- flooding it and causing problems
Its supposed to hold vapors not raw fuel

Look at your gas cap seal- it is smooth or cracked?

Remove the fuse marked CLOCK on passenger side footwell or side of dash with door open(depending on year/model)
should be #13 on the panel
leave out for a minute then reinstall- that forces a master ECU reset and clears codes so you can start fresh

the dealer is giving you the runaround- I would report them to acura

Could you explain more for me?
Every car automatically cut off after the limit?
Is that problem?

Thank you.

Long time ago(before check engine light on), I cleaned the fuel line in the wal-mart car center.
That time, service man remove the some horse in the under the hood and connect their stuff. Then put bottle cleaner into that horse.
After finish(30minutes), reconnect the horse to my car.
As I saw him, it is very hard to work to remove the horse
I doubt that. If some gas(vapor) leak..., it is possible to occur that problem?

fixed. it was probably a vacuum hose, no gas vapors will leak from a vacuum hose.

sangjun

Does the P1457 error code means leak vapor gas from vacumm line?
If not, how does car know the leak of vapor gas?
As I know, leak of gas influence less pressor of fuel line then the sensor check it and send a signal to ECU. Is it correct or Not?
Thank you for your answer.

P1457 Means the ECU has detected a vacuum leak on the canister side of the evaporative emissions system via lower than expected FTP readings.
