Description
The crankshaft position (ckp) sensor system consists of a ckp sensor plate and a pickup coil.
The sensor plate has 34 teeth and is installed on the crankshaft. The pickup coil is made of wound copper wire, an iron core and magnet. The sensor plate rotates and, as each tooth passes through the pickup coil, a pulse signal is created. The pickup coil generates 34 signals per engine revolution. Based on these signals, the ecm calculates the crankshaft position and engine rpm. Using these calculations, the fuel injection time and ignition timing are controlled.
Reference: inspection using an oscilloscope.
Hint:
Monitor description
If there is no signal from the ckp sensor despite the engine revolving, the ecm interprets this as a malfunction of the sensor.
If the malfunction is not repaired successfully, a dtc is set 10 seconds after the engine is next started.

Inspection procedure
Hint:
The engine speed may be indicated as zero despite the engine revolving normally. This is caused by a lack of ne signals from the crankshaft position (ckp) sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the ckp sensor output voltage is insufficient.
Standard: correct values are displayed.
Hint:
Standard resistance
Hint:
Terms cold and hot refer to the temperature of the sensor. Cold means approximately -10 to 50°c (14 to 122°f). Hot means approximately 50 to 100°c (122 to 212°f).
Standard resistance (check for open)
Standard resistance (check for short)
Ok: sensor is installed correctly.
Ok: sensor plate does not have any cracks or deformation.
Hint:
If the engine does not start, replace the ecm.
