Customer Question

Hello, my name is***** codes are all unrelated. P0442 and P0496 would be caused by a failed purge solenoid. P0128 usually means the thermostat has failed. P0014 usually means the Variable Camshaft Timing (VCT) Solenoid has failed but can also set if oil is dirty or low. Let me know if you have more questions or if there is anything else I can do to help. Thanks.

I changed the solenoid on the engine around 6 months ago. When facing the vehicle it was on the left side and I had to remove power steering to replace. Is there another one? How do I get these fixed which I would do myself?

When you replaced solenoid did problem go away? If so, how long? Thanks.

it went away however I believe it was different codes then. I also took off throttle house unit, sprayed throttle with cleaner, drove around then placed back on. When I did that I cleared codes and after doing drive cycle lights stayed off and I passed inspection.

It is the only solenoid so if oil level is clean and full then the solenoid probably needs to be replaced again. Keeping up on oil changes is important with keeping timing system working correctly. I think you should be able to make all of above repairs yourself without any problems. Let me know if you have more questions, thanks.

I did run behind on my oil changes and it went low. Just got changed today along with power steering fluid. Should I clear codes to see if fixed? The solenoid is 6 months old it should still be good correct?

I would clear codes and see if that helps, it will likely take care of P0014 but not the other codes. Solenoid should be good yet. Let me know if you have more questions, thanks.
