replace the K20 ECM.

瀚慖f greater than the specified range, test the 5 V reference circuit for a short to voltage. If the circuit tests normal, replace the K20 ECM.

4. Ignition ON, test for 4.8-5.2 V between the camshaft position signal circuit terminal C and ground.

瀚慖f less than the specified range, test the signal circuit for an open/high resistance or short to ground. If the circuit tests normal, replace the

K20 ECM.

瀚慖f greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K20 ECM.

5. Ignition OFF, connect a fused jumper wire to the camshaft position signal circuit terminal C.

6. Ignition ON, momentarily touch the other the other end of the fused jumper wire to the battery negative post. The scan tool should show the

Camshaft Position Active counter incrementing.

瀚慖f the Camshaft Position Active counter increments, test or replace the B23 camshaft position sensor.

瀚慖f the Camshaft Position Active counter does not increment, replace the K20 ECM.

Component Testing

Note: You must perform the Circuit/System Testing before proceeding with Component Testing.

1. Inspect the camshaft position sensor for correct installation. Remove the camshaft position sensor from the engine and inspect the sensor

O-ring for damage.

瀚慖f the sensor is loose, incorrectly installed, or damaged, replace the B23 camshaft position sensor.

2. Connect the camshaft position sensor harness connector to the B23 camshaft position sensor.

3. Ignition ON, engine OFF. Observe the Camshaft Position Active counter parameter on the scan tool.

4. Pass a flat steel object across the tip of the sensor repeatedly. The Camshaft Position Active counter parameter should increment with each

pass of the steel object.

瀚慖f the parameter does not increment, replace the B23 camshaft position sensor.
