Hi all, I change the gas cap on my Breeze with an aftermarket lockable gas cap, thinking that would take care of the check engine light trouble code P0441. A week later, the check engine light came back again with the same code. Please help me in trying to figure out what needs to be replaced. Research says the following could be the possible fix for the P0441 trouble code:
Replace Leak Detection Pump (appears to be a common Chrysler fix)
Repair damaged EVAP lines or canister
Repair open or short in voltage feed circuit to Purge Solenoid
Repair open in PCM purge command circuit
Replace purge Solenoid
Replace vacuum switch
Repair restriction in Evap line or canister or solenoid
Repair resistance in purge connector
Replace PCM
I prefer to just replace the necessary part(s) with a minimum amount of time and money spent. I'm pressed for time because the car needs a smog check prior to registration renewal due in two weeks. My preference is to do this myself as shade tree mechanic.
An evaporative system test for vacuum leak using a smoke machine was suggested by a website. Unfortunately I don't one, nor have access to one. Is this a necessity?
Since time and money is limited, where should I start? Since the leak detection pump is a common fix, should I start with that? How do I know its bad at this point?
Is a visual inspection sufficient enough to see a damaged evap lines or canister? If it is, what is the symptoms of a damaged evap lines or canister?
Should I replace the purge solenoid, and how do I know the purge solenoid is bad?
How do you repair resistance in purge connector?
How do I know my PCM is bad?
Please help, and thanks in advance.
