Electronic Engine Controls: Notes

The electronic engine controls consist of the following:

• RH and LH Camshaft Position (CMP) sensor
• RH and LH Catalyst Monitor Sensor (CMS)
• Crankshaft Position (CKP) sensor
• Cylinder Head Temperature (CHT) sensor
• RH and LH Heated Oxygen Sensor (HO2S)
• RH and LH Knock Sensor (KS)
• Mass Air Flow (MAF) sensor
• PCM
• Throttle Position (TP) sensor
• RH and LH Variable Camshaft Timing (VCT) oil control solenoids

The PCM needs the following inputs to calibrate the engine correctly:

• Air temperature
• Amount of engine detonation
• Camshaft position
• Crankshaft position
• Cylinder head temperature
• Engine coolant temperature
• Engine RPM
• Exhaust oxygen content
• Mass airflow
• Throttle position
