Computer Reflash

only reason you would need a reflash is that it has been changed or some one has updated the ecu with the wrong setting. now rest is a different thing. that is to remove old stored fault codes and in no way should it cost that much.

ECM has code P0017

the cams and crank are out of time...if thats the only generic DTC you pulled out of the computer. the cam and cranks are out of sync for whatever reason. could be a faulty timing chain tensioner let one of the cams or crank jump one tooth retarded. that is if the only trouble code p0017 is present. if there are more codes present than that, contact your local factory dealer. there may be a recall on the PCM programming. when they put in the updated parameters they call it a reflash.

I have a 2002 Grand Am GT, Ram Air V6. Last year the check engine light came on that indicated the engine temp was too LOW. So I replaced the thermostat and temp sensor. Now the engine light has came on...

Thermostat is the only thing that can cause this fault. Check the thermostat again. Just take it out and see if it's open. If not, maybe you need to reflash your computer. The reference temperature or sensor calibration it is using may be corrupted. If you have more questions, please let me know.

They did a smoke test and replaced the hose that was leaking code still popped up . po440 grand am

p0440 evap small leak detected. Should find with smoke machine. However, there could be a reflash for the computer to prevent this issue. Have the tech check for updated computer programs. If none are available you have a small leak in the fuel vapor system.

Hello. I used to work in a GM dealer. It is seldom the EGR valve that is the problem. If it is code P1404, the problem is a PCM calibration. Take it to a local dealer and they can reflash the PCM. If you want to get technical about it, the PCM is and emission control device and should be covered by warranty for 8 years or 80,000 miles.
