Question about 1993 Pontiac Grand Am
Just had the codes read on my car.. Came up with the error code DTC 34... now I looked up the code on the internet but I'm not really sure what it means.. DTC - 34 MAP sensor circuit error (signal low indicating high vacuum)... Can anyone explain this in layman's terms for me please?
You answered your question. Buy a new map sensor google the location on the engine and replace it

There is a loose connection on the sensor, or clean it with a fine Sandy paper, it's best to replace. If the problem persists, see a specialist.

Trouble Code: P1336
CKP Sensor System Variation Not Learned
Set the parking brake and block the drive wheels for safety. Verify the hood is closed. Read the trouble codes. If a code is set, refer to that code. Start the engine. Allow engine temperature to reach at least 158?F (70?C). Then key off. Select Crankshaft Position Variation Learn procedure on Scan Tool & start the vehicle. Apply the brake pedal firmly and verify the selector is in Park. Increase accelerator pedal position until fuel cutoff is reached at the test rpm (e.g., 5150). Quickly release the accelerator pedal after fuel cutoff is reached. The CKP system variation compensating values are learned when the engine speed (rpm) decreases back to idle speed and the procedure terminates. Read the trouble codes and recheck for DTC P1336. If DTC P1336 runs and passes, the CKP system variation "learn" procedure is complete. If not, look for other codes. If no codes are set, repeat the test procedure.
