Can a crank sensor cause a no start?
Can a crank sensor cause a no start?
The answer is No, since it’s a Hall Effect type sensor. The good news is that the test you’ll learn here is easy to do and you’ll get an accurate result that will either condemn the crankshaft position sensor as the cause of the no start or exonerate it. Contents of this tutorial:
How to test the crank sensor ( Chrysler 2.7L, 3.5L )?
This article will help you to troubleshoot the Chrysler 2.7L, 3.3L, 3.5L crankshaft position sensor (or code: P0320) with a simple but very accurate test using only a multimeter in Volts DC. In case you’re wondering if the crankshaft position sensor can be tested with a simple multimeter resistance test?
What kind of power does a crank sensor need?
This comes in the form of either 5 Volts or 8 Volts, depending on how old your specific Chrysler (or Dodge or Plymouth or etc.) is. The PCM (Powertrain Control Module=Fuel Injection Computer) is the one that provides these 8 Volts to power the crankshaft position sensor.

How to test the crankshaft position sensor Chrysler 2.7L?
Now, remove some of the plastic wire loom protector and/or the black electrical tape that shields the three wires of the crankshaft position sensor to gain comfortable access to the three wires it protects. When done removing some of this black electrical tape, reconnect the connector back to the crankshaft position sensor.
How to test the crankshaft position sensor on the multimeter?
If the crankshaft position sensor is working correctly, the multimeter will register an On/Off voltage of 5 Volts DC. ON is when the multimeter displays 5 Volts DC and off is 0.5 Volts DC. The key to seeing this voltage change is to turn the crankshaft pulley slowly and steadily. OK, let’s interpret the multimeter test results you just obtained:
