5. Ignition ON, test for greater than 4.8 V between the 5-volt reference circuit terminal 3 and the low reference circuit terminal 1.



瀚慖f less than the specified value, test for an open/high resistance in the 5-volt reference circuit. If the circuits/connections test normal,



replace the ECM.



6. Test for 4.8-5.2 V between the signal circuit terminal 2 and ground.



瀚慖f the voltage is greater than specified range, test for a short to voltage in the signal circuit. If circuit/connections test normal, replace the



ECM.



瀚慖f the voltage is less than the specified range, test for a short to ground or an open/high resistance in the signal circuit. If



circuit/connections test normal, replace the ECM.



7. If all circuits/connections test normal, test or replace the crankshaft position sensor.
