How-to: diagnose a P0320 (crankshaft position sensor circuit failure)

This si a how-to video on the correct diagnois of a P0320 as applied to jeep/dodge/Chrysler cars and trucks. this was done on a 1997 jeep wrangler 2.5l 4 cylinder engine. you car or truck may not be exactly the same but the theories and principles are the same for the overall diagnosis. if you have any questions please feel free to email me, tweet at me @thejeepdoctor, find me on facebood and please check out my other videos. thanks!

Crank Sensor Quick Fix
GET SOFTWARE HERE: Crank Sensor Quick-Fix There are two types of crank sensors, and two types of tests, the 2 and 3 wire sensors. Here are the flash points for the crank sensor testing. 1) The 2 wire crank sensor generates a voltage, and is quick tested with a test light. 2) To test the two wire sensor, disconnect the crank sensor, ignition key on, hook the test light to battery power, and tap at each crank sensor terminal repeatedly. A spark click and injector pulse should be seen. 3) The 3 wire sensor has its own circuit, with 5 to 8 volt power, ground, and signal wires. Identify the signal wire using volt meter or diagram. 4) Take the test light and connect to battery ground. With key on, disconnect crank sensor, and repeatedly tap on the signal wire. You should hear a spark click and injector noid pulse. These are to test the ECM crank sensor circuit response. On both tests, you should see a spark click and injector pulse. Crank sensor is the main input to the ECM. If ECM working, then the crank is the only other issue. There are other ways to test, but involve an oscilloscope and more complex. This concludes the cranks sensor Quick-Fix.
