Non-Monitored Circuits
WARNING: This page is about a different car, the 2000 Plymouth Breeze, 2000 Dodge Stratus, and 2000 Chrysler Cirrus. However, it is still accessible from the selected car via links, so may be relevant.
Powertrain Control Module (PCM) does not monitor all circuits, conditions and systems that could cause a malfunction or driveability problem. However, problems with these systems may cause PCM to store Diagnostic Trouble Codes (DTCs) for other systems or components.
For example, a fuel pressure problem will not cause a DTC directly, but could cause a rich/lean condition or misfire which may cause PCM to store a DTC. The major non-monitored circuits are identified below.
- Cylinder Compression
- Excessive Oil Consumption
- Exhaust System
- Fuel Injector Mechanical Faults
- Fuel Pressure
- PCM Connector Engagement
- PCM System Ground
- Secondary Ignition System
- Throttle Body Airflow
- Vacuum Assist
