DESCRIPTION
The Crankshaft Position (CKP) sensor system consists of a crankshaft position sensor plate and Magnetic Resistance Element (MRE) type sensor. The crankshaft position sensor plate has 34 teeth at 10° intervals (2 teeth are missing for detecting top dead center), and is installed to the rear end of the crankshaft. The crankshaft position sensor outputs 34 rotation signals per crankshaft revolution. The ECM uses the G2 signal to distinguish between the cylinders, and uses the NE signal to detect the crankshaft position and engine speed.
| DTC Code | DTC Detection Condition | Trouble Area |
| P0335 | No Crankshaft Position (CKP) sensor signal is sent to the ECM while cranking (1 trip detection logic). No CKP sensor signal is sent to the ECM at an engine speed of 600 rpm or more (1 trip detection logic). | Open or short in Crankshaft Position (CKP) sensor circuit CKP sensor CKP sensor plate ECM |
| P0337 | The output voltage of the CKP sensor is 0.3 V or less for 4 seconds (1 trip detection logic). | Open or short in CKP sensor circuit CKP sensor CKP sensor plate ECM |
| P0338 | The output voltage of the CKP sensor is 4.7 V or higher for 4 seconds (1 trip detection logic). | Open or short in CKP sensor circuit CKP sensor CKP sensor plate ECM |
| P0339 | Under conditions (a), (b) and (c), no CKP sensor signal is sent to the ECM for 0.05 seconds or more (1 trip detection logic): (a) The engine speed is 1000 rpm or more. (b) The starter signal is OFF. (c) 3 seconds or more have elapsed since the starter signal was switched from ON to OFF. | Open or short in CKP sensor circuit CKP sensor CKP sensor plate ECM |
- Standard:
Tester Connection Tool Setting Condition Specified Condition C45-110 (NE+) - C45-111 (NE-) 5 V/DIV., 20 msec./DIV. Cranking or idling The correct waveform is as shown C45-90 (G2) - C45-89 (G2-) 5 V/DIV., 20 msec./DIV. Cranking or idling The correct waveform is as shown
- HINT:
- G2 stands for the camshaft position sensor signal, and NE stands for the crankshaft position sensor signal.
MONITOR DESCRIPTION
If there is no signal from the crankshaft position sensor despite the engine revolving, the ECM interprets this as a malfunction of the sensor.
When the sensor output voltage remains at below 0.3 V, or higher than 4.7 V for more than 4 seconds, the ECM stores DTC(s).
