Circuit Description
WARNING: This page is about a different car, the 2000 Isuzu Hombre. However, it is still accessible from the selected car via links, so may be relevant.
Powertrain Control Module (PCM) uses Camshaft Position (CMP) sensor signal to determine which cylinder is misfiring when a misfire is present. When PCM receives an intermittent signal from CMP sensor, the CMP ACTIVITY counter will increment.
Conditions for setting this DTC are:
- Engine is running.
- CMP ACTIVITY counter does not increment.
