* Close to solenoids, motors, and relays

瀚慍orrect any wire harness routing or component placement conditions if it is determined to be a possible source of electrical interference.

2. Observe the following scan tool parameters are all incrementing:

* Exhaust Camshaft Position Active Counter Bank 1

* Intake Camshaft Position Active Counter Bank 1

* Exhaust Camshaft Position Active Counter Bank 2

* Intake Camshaft Position Active Counter Bank 2

3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Ignition OFF, all vehicle systems OFF, this may take 2 minutes, disconnect the affected B23 camshaft position sensor connector.

2. Test for less than 3 ohm between the low reference circuit terminal 1 and ground.

瀚慖f greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K20

ECM.

Note: The control module or the sensor may be damaged if the circuit is shorted to B+ voltage.

3. Ignition ON, test for 4.8-5.2 V between the 5 V reference circuit terminal 3 and ground.

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

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

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

5. Ignition ON, using a 3 A fused jumper wire connected to ground; momentarily touch the camshaft position sensor signal circuit terminal 2

repeatedly. The appropriate camshaft position active counter parameter should increment.

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.
