Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello, and welcome back. Did coolant get sprayed onto the distributor and or ignition coil?
Did coolant spray onto the PCM or any other electrical connectors?
It is normal for you to get power at the coil for 2 seconds at key on, but it should return when you crank the engine, if the PCM sees the crank sensor sends a valid signal. I wonder if any codes are being set. Try this: Cycle the ignition key 3 times and see if the check engine light flashes a code out. If it does, count the first set of flashes, (which will be the first digit of the code), then count the second set of flashes (second digit). So in other words turn the key on/off/on/off/on. Then watch the light. Let me know if you get a code.
Hall Effect Sensor Testing
To test a Hall Effect Sensor you will need an accurate DC Voltmeter set to the 20 Volt scale.
With the sensor plugged in insert a T-pin in the signal wire cavity of the sensor plug.
Bar the engine over or rotate the shaft the sensor is sensing.
Watch the voltmeter.
As it rotates the signal voltage should go back and forth from low voltage to the specified voltage sent to the sensor. Some Crankshaft and Camshaft Tone Wheels have an ODD Notch to signal an engine position.
If there is no signal, unplug the sensor and check for source voltage at the connector.
Check the ground by powering one meter lead and testing for ground with the other.
If the power and ground are good, replace the sensor.
How's it going with the truck?
