NOTE: If the sensor is removed, be sure to check the sensor tip for metal debris and clutch material and clean it if necessary. NOTE: If this SPN and FMI are active, verify that the wiring from crankshaft position (CKP) sensor pin 1 to pin 73 of the motor control module (MCM) 120-pin connector and that the wiring from CKP sensor pin 2 pin of the MCM 120 – pin connector is correct. PROBABLE CAUSES:1. Crankshaft sensor connector/harness.2. Crankshaft sensor.3. Swapped pins on the connector.
Detroit DD13 EPA07 (2007-09) Fault Code: SPN 636 FMI 2 (MCM) No Match of Camshaft and Crankshaft Signals
Posted by PerDiezel Solutions on
DESCRIPTION:This code will set when there is a camshaft and crankshaft mismatch signal. MONITORED PARAMETER:Camshaft/crankshaft sensors. TYPICAL ENABLING CONDITIONS:Engine idle MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:10 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:None VERIFICATION:Engine idle: One minute. 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.
