GENERAL DESCRIPTION |
The Crankshaft Position Sensor (CKPS) is a magnetic generator type sensor that generates voltage using a sensor and a target wheel mounted on the crankshaft. There are 58 slots in the target wheel with one longer slot. When the slot in the wheel aligns with the sensor, the sensor voltage output is low. When the metal (tooth) in the wheel aligns with the sensor, the sensor voltage output is high. During one crankshaft rotation there are 58 signwave signals with one longer signal. The ECM calculates engine RPM by using the sensor’s signal and controls the injection timing and the ignition timing. Using the signal differences caused by the longer slot, the ECM identifies which cylinder is at top dead center.
DTC DESCRIPTION |
Checking tooth error correction under detecting condition, if the TEC(Tooth Error Correction) is out of Threshold value, ECM sets P0315.
