Testing a CPS
Had a tech in Vancouver B.C explain how to test your CPS, if it starts to fail. He said connect to an ohmeter, should read a steady 850-1200 ohms. using an air heat gun, start warming the sensor (not hot,but warm as it's plastic), keeping a steady ohm reading, and it should not change much. Mine started to go up fast to infinity, or just lose a reading. QWhen it cooled down, reading started.
Anyone have input for this test procedure? Also, he said if the CSP is suspect, watch the tach needle, as it should not jump when it is in the no start mode of the problem. If the tach needle jumps, it is somthing else, not the CPS. Again, anyone with knowledge about this test as well?
