Crank Angle Sensor

Crankshaft angle sensor is a component part of the distributor assembly. 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 180 (4-cylinder) degree signal terminals of ECU. See CRANK ANGLE SENSOR ECU INPUT SIGNAL TERMINALS  table. On a bar graph DVOM, one degree signals should measure about 2.3-2.8 peak volts with engine cranking. The 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 distributor with crank angle sensor.
