Crank Angle Sensor

Crank angle sensor is part of the distributor. If a fault is present in crank angle sensor, Code 11 may be set in ECU memory. If Code 11 is set, perform appropriate CODE 11 (CRANK ANGLE SENSOR) test in TESTS W/CODES article.
To test crank angle sensor, leave sensor wiring connected. Using a logic probe or DVOM with an analog bar graph function, connect negative lead to ground and alternately connect positive lead to 1-degree (position) signal and 120/180-degree (reference) signal terminals of ECU connector. See CRANK ANGLE SENSOR ECU INPUT SIGNAL TERMINALS table.
Measure voltages at both terminals with engine cranking. See CRANK ANGLE SENSOR ECU INPUT SIGNAL VOLTAGES table. If either signal is not present, check harness for short or open circuit. If no problems are found, replace crank angle sensor.

NOTE: It is possible to measure crank angle sensor voltage with a conventional DVOM without bar graph function; however, it may not be easy to determine peak voltage signal due to the averaging of signal.
