(Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).1. ACTIVE DTC When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death.With the scan tool clear the DTC(s).Start the engine and run until operating temp is reached.If the DTC does not reset it may be necessary to test drive the vehicle.Did this DTC set again?YesGo To 2NoRefer to the INTERMITTENT CONDITION Diagnostic Procedure.Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)2. CHECKING THE (K44) CMP SIGNAL WITH A LAB SCOPE

With a lab scope, backprobe the (K44) CMP Signal circuit at the CMP Sensor harness connector.When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death.Start the engine.Observe the lab scope screen.The CMP Sensor is a hall-effect type sensor that produces a 5–volt digital (square wave) signal.Are there any irregular or missing signals?YesGo To 3NoGo To 63. CMP WIRE HARNESS INSPECTIONTurn the ignition off.Visually inspect the related wire harness. Look for any chafed, pierced, pinched, or partially broken wires.Visually inspect the related wire harness connectors. Look for broken, bent, pushed out, or corroded terminals.Make sure the Crankshaft Position Sensor and the Camshaft Position Sensor are properly installed and the mounting bolt(s) are torqued to their proper specification.Refer to any TSBs that may apply.Were any of the above conditions present?YesRepair as necessary.Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)NoGo To 44. TONE WHEEL/PULSE RING INSPECTIONRemove the Camshaft Position Sensor.Inspect the Tone Wheel/Pulse Ring for damage, foreign material, or excessive movement.Were any problems found?YesRepair or replace the Tone Wheel/Pulse Ring as necessary.Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)NoGo To 55. CAMSHAFT POSITION SENSOR If there are no possible causes remaining, view repair.RepairReplace the Camshaft Position Sensor.Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)6. ERRATIC CMP SIGNAL Turn the ignition off.Remove the lab scope probe.When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death. Ignition on, engine not running.With scan tool, erase DTCs.Start the engine.Gently tap on and wiggle the Cam Position Sensor.Ignition on, engine not running.Inspect the Sensor connector and harness connector, and inspect the ECM connector and harness connector for loose, bent, corroded, or pushed out pins/terminals.Inspect the related wire harness and the splices in the CMP circuit.Did this DTC set again?YesRepair the wiring/connector concerns as needed or replace the Camshaft Position Sensor.Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)NoGo To 77. CHECKING THE (K24) CKP SIGNAL WITH A LAB SCOPE

Turn the ignition off.With a lab scope, backprobe the (K24) CKP Signal circuit at the CKP harness connector.When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death. Start the engine.Observe the lab scope screen.The CKP Sensor is a hall-effect type sensor that produces a 5–volt digital (square wave) signal.Are there any irregular or missing signals?YesGo To 8NoGo To 108. CKP WIRE HARNESS INSPECTIONTurn the ignition off.Visually inspect the related wire harness. Look for any chafed, pierced, pinched, or partially broken wires.Visually inspect the related wire harness connectors. Look for broken, bent, pushed out, or corroded terminals.Make sure the Crankshaft Position Sensor and the Camshaft Position Sensor are properly installed and the mounting bolt(s) are torqued to their proper specification.Refer to any TSBs that may apply.Were any of the above conditions present?YesRepair as necessary.Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)NoGo To 99. MAGNETIC RING INSPECTIONRemove the Crankshaft Position Sensor.Inspect the Magnetic Ring for damage, foreign material, or excessive movement.Were any problems found?YesRepair or replace the CKP Magnetic Ring as necessary.Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)NoReplace the Crankshaft Position Sensor.Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)10. ERRATIC CKP SIGNAL The conditions that set this DTC are not present at this time. The following test may help in identifying the intermittent condition.When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death. Start the engine.Gently tap on and wiggle the Crank Position Sensor.Turn the ignition off.Inspect the Sensor connector and harness connector, and inspect the ECM connector and harness connector for loose, bent, corroded, or pushed out pins/terminals.Inspect the related wire harness and the splices in the CKP circuits.Were any problems found?YesRepair the wiring/connector concerns as needed or replace the Crankshaft Position Sensor.Perform the ECM Verification Test Ver. 1. (Refer to 9 - ENGINE - STANDARD PROCEDURE)NoTest Complete.
