2005 Chevy Impala Crank Sensor Trouble Code (P0335)

To learn more troubleshooting techniques go to www.scannerdanner.com Once again, this video covers why we need to learn proper troubleshooting techniques and to not be so reliant on manufacturer "flow charts". If you think your engine computer is bad, you must watch this video! Are there more tests that can be done to prove a computer is bad? What else should you check before computer replacement? The following is a list of other tests and how to checks that were performed in this video: 1. How to test a 24x hall effect crank sensor 2. How to test sensor wiring integrity (both opens and shorts to ground) 3. How to test a hall effect cam sensor 4. How to test computer powers and grounds. 5. What is a shared reference circuit? 6. What do you do when you have low reference or power supply voltage to a hall effect?

Crank Sensor Quick Fix
GET SOFTWARE HERE: http://www.autodiagnosticsandpublishing.com/Software_Catalog.html 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.
