Knock Sensor (KS)

WARNING: This page is about a different car, the 1995 Ford Pickup, 1995 Ford Econoline, 1995 Ford Club Wagon, and 1995 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

KS is located on cylinder block. Before continuing diagnosis, check condition of engine, quality of fuel and basic spark timing. Faults in sensor or circuit should set a diagnostic trouble code. See QUICK TEST in TESTS W/CODES - EEC-IV (4.9L) article. If no diagnostic trouble code has been set, proceed to the CIRCUIT TEST DG in the TESTS W/CODES - EEC-IV (4.9L) article for additional sensor specifications and circuit testing procedures. Sensor is tested by substitution or by manually generating a knock to ensure sensor will set a diagnostic trouble code.
