CRANKSHAFT POSITION SENSOR SPECIFICATIONS

Scheme 23

Scheme 23: Waveform

This example shows a typical Crankshaft Position Sensor (CKPS) and Camshaft Position Sensor (CMPS) waveform at idle.

The PCM controls the injection and ignition timing by using these signals. Generally CKPS signal is used to detect the piston's position and CMPS signal is used to detect the Top Dead Center of each cylinder.

Scheme 24

Scheme 24: Waveform

If you release the accelerator pedal suddenly after engine running about 4000 RPM, fuel supply will stop for short period and the O2 sensor service data in the Hi-Scan (Pro) will display values 200 mV or lower. When you suddenly press on the accelerator pedal down, the voltage will reach 0.6 ~ 1.0 V.

When you let the engine idle again, the voltage will fluctuate between 200 mV or lower and 0.6 ~ 1.0 V.

In this case, the O2 sensor can be determined as good.
