瀚慖f the camshaft position active counter does not increment, replace the K20 ECM.
瀚慖f the circuits test normal, replace the B23 camshaft position sensor.
Component Testing
Note: You must perform the Circuit/System Testing before proceeding with Component Testing.
1. Inspect the B23 crankshaft position sensor for looseness and correct installation. Remove the crankshaft position sensor from the engine and
inspect the sensor and the O-ring for damage.
瀚慖f the sensor is loose, incorrectly installed, or damaged, repair or replace the B23 crankshaft position sensor.
2. Connect the crankshaft position sensor connector to the crankshaft position sensor.
3. Ignition ON, observe the applicable camshaft position active counter parameter with a scan tool. Pass a steel object by the tip of the sensor
repeatedly. The camshaft position active counter parameter should increment.
瀚慖f the function does not perform as specified, replace the B23 camshaft position sensor.
