How do you replace a crank sensor on a Chrysler?
How do you replace a crank sensor on a Chrysler?
Remember that only the top of the sensor’s body, where the electrical connector plugs into, will be visible. The magnet at the bottom is inserted into the engine block or bracket. Remove the starter motor or any other component that interferes with the replacement of the sensor.
Why does my Chrysler minivan have no crank?
If you still don’t have power coming out of those wires from the PCM, you have a bad PCM. If you now have power, you’ve got a short in the wiring harness to those sensors. A short will cause the PCM to appear dead. Shorts in the CMP and crankshaft position sensor are COMMON.
How do you start a no crank car?
Once the relay coil is grounded, the contacts provide power to the starter solenoid and that provides power to the starter motor. See how simple that was? Start by checking fuses. If they’re good, pull the starter motor relay and use a digital multimeter to check the supply and ground side of the relay coil (key in START position).
What should I do if my Dodge Ram won’t start?
If it starts you have a poor ground between batter (neg) and the block. This problem is not limited to dodge. Check the body ground under the battery tray and the wires leading to it. While the battery and tray are out of the way it’s an opportune time to remove the adjacent fuse and relay box and check the connectors underneath it for corrosion.

Where can I find the crankshaft position sensor?
Find the crankshaft position sensor. On some models, you will be able to find the sensor hidden somewhere around the starter motor. Other engine models might have the sensor closer to the transmission. Remember that only the top of the sensor’s body, where the electrical connector plugs into, will be visible.
How is resistance tested on a crank sensor?
Only the 2 wire reluctor type crankshaft position sensor can be resistance tested. As you turn the key and crank the engine, each one of the three wires that connect to the crankshaft position sensor have a specific job to do: One delivers power in the form of 5 or 8 Volts from the PCM. This thru’ the wire labeled with the number 3.
What kind of sensor does a Chrysler 2.0L have?
The crankshaft position sensor, on your Chrysler 2.0L/2.4L equipped car or mini-van, is a Hall-Effect three wire crankshaft position sensor. Since the crankshaft position sensor is a Hall Effect type sensor, it produces an On/Off DC voltage signal that can be easily measured with: A multimeter. An oscilloscope. Or an LED Light.
What does the crank sensor on a Chrysler do?
The crankshaft position sensor on your Chrysler vehicle is part of the ignition system and monitors engine speed. The engine computer uses electrical current signals from this and other sensors to change ignition timing for better engine performance.
