P0341-64: Camshaft Position Sensor “A” Circuit Range / Performance – Camshaft sensor general electrical failure Overview: DTC Description (User Friendly) Camshaft sensor general electrical failure ECU Pin Number A037, A052, A051 Customer Symptom Possible no start condition, Poor fuel economy (if Engine Starts), Cruise Control Off, Reduced Torque Mode activated. Fault Effects (On Vehicle) Cruise Control Off, Reduced Torque Mode activated. Lamp Status (If Any) MIL OFF, CEL OFF Fault Detection Condition (Root cause) In between of several crankshaft revolutions there are too many or too less camshaft edges present or the distance or the series of the camshaft edges is implausible. The defect de-bounce counter is incremented at each implausible camshaft revolution, if reaches the counter the threshold (4) the error is set. Normal Operating Condition If during the number (threshold value), of crankshaft revolutions all camshaft edges are present and all edges are inside the calibrated tolerance, the error is healed. For the plausibility check of the camshaft signal the pattern matching of the synchronization is used. Probable Trouble Area Wiring Harness connections between Camshaft sensor and EMS ECU. Camshaft position sensor 5-volt supply circuit shorted to voltage Camshaft position sensor position sensor signal circuit shorted to voltage Camshaft position sensor position sensor ground circuit shorted to voltage Camshaft position sensor 5-volt supply circuit open/high resistance Camshaft position sensor signal circuit open/high resistance Camshaft position sensor ground circuit open/high resistance Camshaft position sensor 5-volt supply circuit shorted to ground Camshaft position sensor signal circuit shorted to ground Camshaft position sensor 5-volt supply circuit shorted to the cmp sensor ground circuit Camshaft position sensor signal circuit shorted to the cmp sensor ground circuit Camshaft position sensor or camshaft EMS ECU faulty Healing Condition Rectify the error Clear through diagnostic tool Ignition OFF & ON
