I had a Check engine light come on the other day, while driving to work, not sure why? Anyway the code is P04543, evaporative emission control system. I think it is a low or high voltage reading on my tank pressure sensor. Anybody have this problem before? I don't know if the sensor is bad or there is a vacuum hose that has come loose. Any help would be appreciated.
Thanks

 

Please confirm the code. I believe there is a typo. No such code. There are several EVAP related codes. Each one has a slightly different diagnosis.
It's gotta be one of the following for EVAP:
P0450
P0451
P0452
P0453

 

oh yea, I cant type, the code should be P0453, sorry.

 

1. Check vacuum lines of FTP sensor for misrouting, leakage, breakage and clogging.

Are vacuum lines OK?

YES - Go to 2.
NO - repair or replace lines.

(At this point, you need Honda test equipment. You'll need to go to the dealer.)

2. Reset ECU

3. Remove fuel cap.

4. Turn ignition swich ON.

5. Monitor FTP sensor V with PGM tester .................................................

 

I'm fixing the thread title
