Crankshaft Angle Sensor
- Crankshaft angle sensor is a self-contained unit located on left front of engine. If a fault is present in crankshaft angle sensor, Code 11 may be set in ECU memory. If Code 11 is set, proceed to TESTS W/CODES article in the ENGINE PERFORMANCE Section.
- To test crankshaft angle sensor, remove crankshaft 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 90/120/180 degree signal terminals of ECU (terminals 1 and 2 respectively). See Fig 1 .
- Rotate sensor by hand. On a DVOM, one-degree signals should measure about 2.3-2.8 peak volts with sensor rotating. The 45/60-degree signal should measure about .1-.4 peak volt with sensor rotating. If either signal is not present, replace crank angle sensor. Also see SUB-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 "averaging" of signal.
