P Codes

NOTE:
1. Do not replace the engine control module (ECM) until a thorough terminal check reveals there are no short/open circuits.
2. After the ECM detects a malfunction, a diagnostic trouble code is recorded when the engine is next 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.
3. Sensor 1: indicates sensors which are mounted closest to the engine.
4. Sensor 2: indicates sensors which are mounted next-closest to the engine.
