Does anybody know? I changed the thermostat and erased the code, drove for 5 minutes. The engine light is now on with the same code.

 

Does anyone know much about this code? I changed the thermostat, checked the coolant and erase the code and drove about 5 miles, the check engine light come on again with the same code.

 

Did you use a OEM thermostat with correct degree rating?... NEVER NEVER use lower rated T'stats

Is the engine getting up to normal operating temperature? If it is then you may have a bad coolant temperature sensor. If you have a scanner you can read the ECT that the PCM is recieving from the ECT sensor.

Another possibility could be a flakey O2 sensor. You can read the values of the O2 sensors with a scan tool.
