DIAGNOSTIC TROUBLE CODE CHART

P0101 - P0130:

P0131 - P0448:

P0451 - P0742:

P0743 - P2229:

NOTE: Do not replace the powertrain control module (PCM) until a thorough terminal check reveals there are no short/open circuits.

NOTE: Check that the PCM ground circuit is normal before checking for the cause of the problem.

NOTE: After the PCM detects a malfunction, a diagnostic trouble code is recorded the next time the engine is started and the same malfunction is re-detected. However, for items marked with a "*", the diagnostic trouble code is recorded on the first detection of the malfunction.

NOTE: Sensor 1 indicates the sensor mounted at a position closest to the engine, and sensor 2 indicates the sensor mounted at the position second closest to the engine.
