Cylinder Identification (CID)
WARNING: This page is about a different car, the 1995 Ford Aerostar. However, it is still accessible from the selected car via links, so may be relevant.
CID is integral with Camshaft Position (CMP) sensor. Faults in CID circuit should set a diagnostic trouble code. See QUICK TEST in TESTS W/CODES - EEC-IV (3.0L) article. If diagnostic trouble code has not been set, proceed to CIRCUIT TEST DR in the appropriate TESTS W/CODES - EEC-IV (3.0L) article for testing.
