Vehicle will not start. I have replaced the CKPS sensor with a used one, but it still brings back the code P0335. before I shell out cash for a brand new sensor. Am I on the right path?

Here are my test results:

Power supply meets specification: B+ Power Supply Circuit Inspection


CKPS Power meets specification: 4.98V

CKPS Power Supply Circuit Inspection


Signal Circuit check for short to ground in harness: DMM reads 0.25 ohms Signal Short to ground in harness


Signal Circuit check for short to battery harness: DMM reads 0.45 ohm

Signal Short to battery harness


Signal Circuit check for open in harness: DMM reads between 0.1 ohms and 0.2 ohms and makes the continuity sound

Signal Circuit open in harness


Ground Circuit Inspection : DMM reads 0.1 ohms and makes the continuity sound

Ground Circuit check for open in harness


I doubt that I have a bad Crankshaft Position Sensor (Crank Angle Sensor)? I also doubt that the PCM is bad. What is the best way to hunt down and eliminate these shorts without tearing out the wiring.


  • Does the error code appear before you use the starter motor? – HandyHowie Feb 15 '18 at 11:26
  • @HandyHowie: Could you rephrase the question? I am not sure that i follow your drift. – ElectronicsNewbie Feb 15 '18 at 11:36
  • Does the error code appear when you turn the ignition on, or does it only appear when you try to start the engine? – HandyHowie Feb 15 '18 at 11:42
  • It does not appear when I turn the ignition on, it only appears after trying to start the engine – ElectronicsNewbie Feb 15 '18 at 11:46
  • My question is trying to determine whether the engine ECU is immediately detecting the faulty CKPS, or it is noticing that there are no pulses being returned when the engine is turned over. – HandyHowie Feb 15 '18 at 11:47
