NOTE
1.
Do not replace the engine control module (ECM) until a through 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. 02: Heated oxygen sensor
4. Sensor 1: indicates sensors which are mounted closest to the engine.
Sensor 2: indicates sensors which are mounted next-closest to the engine.
