I have a problem on my chevrolet the check engine light on and the code is p0010 p0128 and p0641 thank you.


Causes A code P0010 may mean that one or more of the following has happened:
  • Faulty oil control valve (OCV)
  • Open or short in the VVT/VCT circuit
  • Open or short in the OCV / solenoid valve
  • Damaged computer (PCM)
Possible Solutions Some recommended troubleshooting and repair steps are:
  • Carefully inspect the Bank 1 VVT/VCT system circuit wiring and connectors, repair as required
  • With a warm engine, test the operation of the OCV, replace/repair as needed

A code P0128 may mean that one or more of the following has happened:
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature sensor ECT
  • Faulty intake air temperature (IAT) sensor
Possible Solutions Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code:
  • Verify coolant strength & level
  • Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary.
  • Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary.
  • Verify proper intake air temperature (IAT) sensor operation, replace if necessary.
  • If the above items check out good, replace the thermostat
P0641 is a generic code for a possible bad ECU. I would first fix the other two issues and then clear the check engine light and see if it comes back on. If it does, then you have a possible bad ECU and will need to run further tests to see if that is the case or not

BMW 325ci - Car cuts off on very hot days - Error code P00128


Check the following :

BMW Code PO128
This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125
In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant

temperature (ECT) sensor reading, and the speed of the vehicle.

You will likely not notice any drivability problems other than the MIL illumination.
