Saturn Trouble Codes

Code Retrieval Prodecure

See GM trouble code retrieval procedure to retrieve the trouble codes.

The Check Engine light will light when the ECU stores a trouble code.

Counting the Flashes

To retrieve trouble codes, turn the ignition key to the “on” position with the engine OFF.

The Check engine light will flash many short blinks. The total number of blinks equals the code number. For example, flash,pause, flash,flash = code 12.If more than one code is stored, the Check engine light will flash the codes in sequence (lowest to highest) with a pause between each code. The codes will repeat until the key is turned to the OFF position.

1996-up models:

Are OBD2 systems and require a scanner to access the codes.

  1. I have a 1996 Saturn SL and I’m trying to find them fault codes or what the f*** codes are telling me. I have codes

    can anyone tell me what these codes mean? Hopefully waiting.

    1. Patrick-

      P1650 and P1651 refer to Quad Driver B, which appears to be part of the PCM, though I don’t think I would simply jump to replace the PCM. Depending on demand, the QDB grounds the MIL, Upshift Lamp, Cooling Fan Relay, and AC Relay. Check and repair the circuits for these, first. From what I’m reading elsewhere, a short circuit on any of these can burn out the QDB, which would indeed require PCM replacement, but be sure there are no short-to-ground issues that feed it.

      The other two codes I believe you can ignore.


  2. I have a 2008 Saturn Aura and I get the following codes. P1516, P1682, P2101. I recently put in a new throttle body and I still get reduced power and traction control warnings. But not until after the car warms up for a little while. I’d say after driving about 15-20 miles. Then it will start the engine reduced power. I also replaced the ignition switch and both camshaft intake and exhaust solenoids. I have researched and found out that this car has been know for this issue. What can I do to correct this issue?

    1. I had the same issue, I eliminated it by replacing the speed sensor ( accelerator pedal Assy) and with a new Throttle Body. All is now back to “Normal” operations!

  3. How expensive is it to repair a Saturn Vue Code P1133 HO2S insufficient switching switch? Anybody have any ideas? Is it unsafe to drive until it gets fixed? Thanks everyone!
