DESCRIPTION:Crankshaft position sensor failure. MONITORED PARAMETER:Crankshaft position sensor. TYPICAL ENABLING CONDITIONS:Engine idle MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:2 seconds DASH LAMPS:MIL VERIFICATION:Engine idle NOTE: If code 723-3, 723-4, 636-3, or 636-4 active fix those first. PROBABLE CAUSES:1. Verify proper camshaft timing and gear lash adjustment.2. Camshaft position sensor failure.3. Camshaft position sensor harness/connector.

NOTE: If the sensor is removed, be sure to check the sensor tip for metal debris and clutch material. Clean it if necessary. PROBABLE CAUSES:1. Crankshaft sensor connector/harness.2. Crankshaft sensor.

DESCRIPTION:Crankshaft position sensor time out. MONITORED PARAMETER:Crankshaft position sensor. TYPICAL ENABLING CONDITIONS:Engine idle MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:10 seconds DASH LAMPS:1. MIL2. CEL VERIFICATION:Engine idle: One minute. PROBABLE CAUSES:1. Crankshaft sensor connector/harness.2. Crankshaft sensor.

NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If other codes are present, fix those first. Otherwise, check other modules for codes as well and communication status. Fix those first.

NOTE: Please see the step by step troubleshooting procedures for this specific code. PROBABLE CAUSES:1. Wiring between the wastegate control solenoid and the 120-pin MCM connector.2. Wastegate control solenoid failure.
