TASK 5: Cam shaft position sensor CMP
1 It is also of very simple procedure like CKP.
2 Locate the sensor. Normally it is located either end of the head assembly.
3 Run the engine and set the multi meter in the AC millivolt range.
4 Measure the voltage using the probes.

5 Normal range would be 200 mV. Also refer the manufacturer’s manual for the exact readings. It mayvary
manufacturer to manufacturer.
6 If not develops any voltage sensor may be opened. Replace it.

TASK 6: Checking of Accelerator pedal position sensor (Fig 1)

Fig 1

1 Remove APP sensor assembly.
2 Connect three 1.5 V batteries in series as shown in figure and check that total voltage is 4.5-5.0V.
3 Connect volt meter and batteries to APP sensor as shown in figure.
4 Check the APP sensor voltage variation depending upon accelerator fully depressed and released condition.If
the voltage is not varied replace the APP sensor.
