Crankshaft Position Sensor (58X) derives its name from the fact that current systems utilize a Crankshaft Position Sensor, coupled with a 58-tooth crankshaft wheel, to determine crankshaft angular position. Each edge of the wheel corresponds to a change in crank sensor output voltage as a tooth edge passes the sensor. The sensor will produce 58 pulses with one rotation of the crankshaft.
Checking output signals from CKPS every 7.8 sec. under detecting condition, if an output signal is missing or redundant for more than 1.56 sec., PCM sets P0336. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycle.
Item | Detecting Condition | Possible cause |
DTC Strategy | ● Detecting extra/missing pulses between consecutive 58X reference pulses | ● Poor connection ● Noise ● Short in harness ● Target wheel ● PCM |
Enable Conditions | ● Engine running state | |
Threshold value | ● Extra/ missing pulses > 2 pulses | |
Diagnosis Time | ● Continuous (More than 1.56 sec.failure for every 7.8 sec.test) | |
MIL On Condition | ● 2 driving cycles |
Resistance | 825 ±100Ω |
