Crankshaft Angle Sensor

Crankshaft angle sensor is part of distributor. If a fault is present in crank angle sensor, code 11 may be set in ECU memory. If code 11 is set, proceed to code 11 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, touch negative lead to ground and positive lead to one degree and 120/180 degree signal terminals of ECU. See CRANK ANGLE SENSOR ECU INPUT SIGNAL TERMINALS table in this article. On a DVOM, one degree signals should measure about 2.3-2.8 peak volts with engine cranking. The 120/180 degree signal should measure about .1-.4 peak volt with engine cranking. 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, peak voltage signal may not easily be determined due to the "averaging" of signal.
