There is no 1 magic fix for for the DTC you have. The PCM see's a vapor leak on the canisister side of the EVAP system. You can't see a vapor leak unless you have a smoke generator designed for EVAP testing. Last time I checked they ran about $1500.

It can be an actual leak, or a mechanical problem with several solenoids and valves or an electrical problem.

If you want to fix it yourself, following the DTC troubleshooting in the Helm manual is the best advice I can give.

 

my bad to bring this up...

but i have one question.

is there absolutely NO WAY that a loose gas cap can trigger 1457? - can the P1457 be caused BY a loose cap? - soemthing gets into vapor canister..blah blah..
?

Reason is:

I got code P1457. didnt know what it was til later that night since I had to go to school. checked my gas cap after reading the forums and it was really loose - like one click kind of loose. tightened it up, read the code, and i just erased it. i guess ill find out tommroow if the code comes back, but yeah. most likely vapor canister?

DAMNIT. thats two cars in a row w. this stupid emssisons bull

 

did you not read this thread? Someone mentioned that it wasn't the cap!!

 

Yes I did, thanks

I was asking if it was possible a loose cap did something TO INDUCE the new code. just a FMI (for my info?).

cuz my cap WAS loose. and i DID get the code.

 

just for everyones info.....only drove like mebb 5o miles since the last question...but the code did NOT come back yet (after resetting and tightening gas cap..)
:knocks on wood:

could slows2k have been wrong?

i hope so cuz i dont wanna buy a new freakin solenoid...maybe it was just a random prob.

ill update again if i do get the code again..

 

No.

Until your car passes the p1457 monitor 2x, you haven't fixed anything. Driving distance has nothing to do with how many times the monitor has ran.

 

damn! and here i was hoping...

haha, ill be sure to update tho, if i never update that means i got the code really randomly.


time to save money again i guess

 

hmm, i thought that 1457 meant that your car came with the rocket launcher factory option, i was happy when mine came on..... maybe i should check it out??

 

haha. well..if it did, thered be a lot more cars that arent on the road..

 

ah, sad times. CEL came back on. after 100 miles+ were put on it.
