SOURCE: 2005 pontiac grand prix, code p0641 came on. What

DTC P0641 The powertrain control module (PCM) provides a 5-volt reference to the following sensors:

The throttle position (TP) sensor 1
The accelerator pedal position (APP) sensor 2
The engine cooling fan speed sensor
The AC pressure sensor
The fuel tank pressure (FTP) sensor
The oil pressure sensor (OPS)
The PCM monitors voltage on the 5-volt reference circuit. If the voltage is higher or lower than required, DTC P0641 will set.

Conditions for Setting the DTC
The PCM detects a voltage that is higher or lower than required on the 5-volt reference circuit. The above condition is present for 1 second. Action Taken When the DTC Sets The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails. The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
Conditions for Clearing the MIL/DTC The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail. A current DTC, Last Test Failed, clears when the diagnostic runs and passes. A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic. Clear the MIL and the DTC with a scan tool.

Yes i can be dangerous, depending which issues mentioned above has triggered the code such as a faulty gas peddle position sensor. the code can also cause a reduced engine power to activate.

Thank you for using Fixya and best advice is to have the dealer address these issues. A tech 2 scanner would be needed to address the P0641 DTC code.

P0411 is The Secondary Air Injection system. It is used on cold starts to run fresh air into the exhaust to help fire the cat up.

Look around for a broke hose that goes from the intake system to the exhaust that is controlled by a solenoid.

Their are three phases that will trigger codes your code is phase 1 of the systems operation.

I would take the vehicle to a shop to have this serviced. Or you can ignore the code. Their wont be any detrimental affect other than if you have smog or e-check your car will fail.

Most likely airpump check valve went bad causing electric air pump to burn out. Replace valve & air pump.

SOURCE: Grand Prix pontiac error code p0411 and p2440

P0441 has to do with your evaporative emission system. This code is flagged when flow is incorrect.
P2440 refers to the Secondary Air Injection system. It means that the switching valve is stuck open.

    For pontiac grand prix what does trouble code


    Appears to be the code for the camshaft position sensor, or cam sensor circuit. Around $35-45.00 for the part at an auto parts store. Have the part replaced. And take it from there. Might be a good thing to replace the spark plugs and wires too.
