瀚慖f less than the specified value, test the 5-volt reference circuit for an open/high resistance. 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, replace the camshaft position sensor.
