I have an 04 Tundra with the 5.7 v8 motor. Recently my check engine light came on. The garage told me it was an air sensor possibly. They suggested that I put a new gas cap on and then reset it. It came on again after I changed the cap. This is the 3rd time. What could be wrong? Or how do I fix it. Thanks kpost
I forgot it has 188,890 original miles. Oil and transmission changed timely.
Clarification: Which specific code or codes are you getting when you hook up a scan tool?
I am not allowed in the garage they just said it was an air code and they told me to put a new cap on it. So I did and it still doesn't work. I can try to call the garage tomorrow and see if they can remember.
An "air code" could be a reference to an EVAP valve control solenoid problem but that's just a guess. Take it to a major auto parts store and have it scanned for free then report back with the code(s).
Code # is the same po442
There is a small leak in the EVAP system. Hoses, canister, connection between filler neck and gas tank, all need to be checked for leaks.
Code # is the same po442
Mechanic is doing a smoke test on it tomorrow. He said he thinks the leak or issue is or may be where you guys stated above . Will let you know thanks for the help. Kpost
