Powertrain Control Module (Pcm)

The Powertrain Control Module (PCM) is located at the rear of the engine compartment, between the bulkhead panel and the secondary bulkhead panel on the opposite side to the hand of drive. The PCM is secured to a mounting bracket with four screws. The bracket is attached to the bulkhead panel.

The PCM has the capability of adapting its fuel and ignition control outputs in response to several sensor inputs.

The PCM receives inputs from the following:

• Crankshaft Position (CKP) sensor
• Camshaft Position (CMP) sensor (4 off)
• Engine Coolant Temperature (ECT) sensor (2 off)
• Knock sensor (2 off)
• Manifold Absolute Pressure (MAP) sensor
• Mass Air Flow and Temperature (MAFT) sensor (2 off)
• Manifold Absolute Pressure and Temperature (MAPT) sensor
• Accelerator Pedal Position (APP) sensor
• Heated Oxygen Sensor (HO2S) (4 off)
• Ambient Air Temperature (AAT) sensor
• Fuel Rail Pressure and Temperature (FRPT) sensor
