Code 452 look for these items
DTC P0452 indicates a low voltage problem in the Fuel Tank Pressure Sensor (FTPS). What the fuel FTP sensor does is convert fuel tank absolute pressure into electrical signals and inputs the signal to the ECM/PCM.
First thing to do is make sure the gas cap is good and tightened properly. Then check the vacuum lines and wiring at the FTPS to be sure they are good, clean and tight.
Barring a wiring problem it can be a bad FTPS or PCM.
Should be located back by the fuel tank.
A code P0440 could mean one or more of the following has happened:
* The gas cap is not installed or working properly
* The purge solenoid has failed
* The canister is plugged and not working properly
With a P0440 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
* Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
* Inspect the EVAP system for cuts/holes in tubes/hoses
* Inspect for damaged or disconnected hoses around the Evap purge solenoid
* Check and/or replace the sensor
* Check and/or replace the purge valve
* Have a professional use a smoke machine to detect leaks
Cylinder #6 misfire.
:mrgreen: :twisted: 8) ?
If you look above at the first two codes you will note they both reference a possible gas cap problem. Check or replace the cap and reset computer. The MAF and the misfire. How long after the plug replacement did this start to occur? It is possible to have a bad wire to #6 or a cracked plug.
