p0443 trouble shooting HELP!
Hi guys.
I have a 2003 Honda Accord Euro R and a while back I got this error code after I replaced my intake.
I know this error code has to do with an electrical problem in the EVAP Canister Purge Valve circuit and I'm thinking it may be due to me accidentally mixing up the connectors of the Evap solenoid and the TPS / IAC / MAP sensor (cant remember which one it was but two of those sensors have identical connectors).
After doing that, I got this error code ever since.
I've done allot of reading up on this trouble code and how to trouble shoot it but I'm not 100% sure how to proceed.
I've measured the voltage at the connector and it's measuring 0V, So I thought maybe there's a fuse that blew? But I cant seem to find a fuse labelled for the EVAP solenoid. Anyone know which fuse controlls that? Either way I went over all the fuses and they all looked fine.... But I'd still like to know if there's a specific fuse for this.
If it's not a fuse, I looked up the pinout for the ECU and I'm going to check if there's any voltage there. If there is.... I'm guessing maybe the wire may be damaged? Can I just run a new wire to the sensor? Here I'm coming back to the fuse question....
If there is NO voltage.... What then? Bad ECU?
Hope somebody can help me out with this.... I really hate electrical troubleshooting!
