Self-Diagnostic System: Notes

Electronic Control Module (ECM) recognizes faults (open circuits, short circuits, missing signals, or a continuously applied signal voltage) in the following circuits/components.

• Crankshaft Position (CKP) Sensor
• EGR Frequency Valve
• EGR Temperature Sensor
• Engine Coolant Temperature (ECT) Sensor
• Fuel Evaporative (Frequency) Valve
• Heated Oxygen Sensor (HO2S)
• Hall Effect Sensor
• Idle Air Control (IAC) Valve
• Intake Air Temperature (IAT) Sensor
• Knock Sensors
• Throttle Position (TP) Sensor
