M162 ENGINE CONTROLS 1F1 -- 23 DAEWOO MY_2000 KAB1F150 Failure Code Description Trouble Area Maintenance Hint 17 Crankshaft position sensor signal failure (no engine revolution signal) Even through cam position recognition is normal, no crankshaft position signal recognition D Monitoring the actual rpm through or scan tool 18 Crankshaft position sensor signal failure (rpm > max. value) When more than applicable revolution values or implausible to 60 – 2 teeth scan tool D Inspection the ECM pin 100, 99 about short circuit with bad contact D Inspection the CKP sensor 20 Crankshaft position sensor signal failure (gap recognition failure) When implausible recognition of cam and crank angle signal or intermittent sensing the signal or error count of undetected gap. p D Inspection the air gap between sensor and drive plate D Inspection the drive plate (teeth condition) D Inspection the ECM 67 Crankshaft position sensor adaptation failure When faulty crank angle sensor adaption p Circuit Description The 58X reference signal is produced by the CKP sensor. During one crankshaft revolution, 58 crankshaft pulses will be produced. The ECM uses the 58X reference signal to calculate engine rpm and CKP. The ECM constantly monitors the number of pulses on the 58X reference circuit and compares them to the number of Camshaft Position (CMP) signal pulses being received. If the ECM receives and incorrect number of pulses on the 58X reference circuit, this failure code will set. Crankshaft Position Sensor Resistance Inspection 1. Disconnect the coupling “E” of ECM while the ignition switch is in “OFF” position. Specified Value 1,050 ~ 1,400 Ω Notice: Measure the insulator resistance of the CKP sensor if out of the specified value. |
