What kind of DC does a crank sensor need?
If you’re testing for a short to Ground, a short to power, or an open in this circuit, you’ll need to unplug all of the sensors/components this sensor Ground wire connects to. The PCM provides 5 Volts DC on the PPL/WHT wire to a total of 4 components (including the crankshaft position sensor).
What should the CKP sensor read on a crankshaft?
Touch the DMM red lead to the red (power) wire on the harness connector. You may need to check the wiring diagram for your particular model, if the CKP sensor uses wires of different color to identify the ground, power and signal wires. Turn the ignition key to the On position. Your meter should read between 5 and 13 volts.
How to test the crank sensor in 1994?
How To Test The Crank Sensor (1994-1996 3.9L, 5.2L, 5.9L Chrysler). How To Test The Crank Sensor (1997-2001 3.9L, 5.2L, 5.9L Chrysler). The PCM provides a sensor Ground on the BLK/LT BLU wire to a total of 11 components (including the crankshaft position sensor).
What to do if your crankshaft position sensor is bad?
Touch the signal wire with the red probe from your meter and the ground wire with the black probe. Compare your reading to the specification in your vehicle repair manual. If the voltage signal is lower than the specification, most likely the sensor is bad.
What should the voltage be on a crankshaft sensor?
Touch the DMM red lead to each of the sensor wires on the harness connector you just unplugged. One of the wires should produce around 1.5 volts; otherwise, the sensor is not receiving a reference voltage, and needs to be fixed. Disable the fuel system by removing the fuel pump fuse or relay.
Touch the DMM red lead to the red (power) wire on the harness connector. You may need to check the wiring diagram for your particular model, if the CKP sensor uses wires of different color to identify the ground, power and signal wires. Turn the ignition key to the On position. Your meter should read between 5 and 13 volts.
How do you backprobe a sensor on a crankshaft?
With some sensors, you may backprobe the wires through the sensor electrical connector. If this isn’t possible, see if you can unplug the sensor connector. If so attach a strand of copper wire to each terminal on the connector. Then, plug the connector back in so that the two strands stick out through the connector’s housing.
