How many ohms should a cam sensor have?
The readout should indicate a resistance value, usually between 200 and 2000 ohms, depending on your particular vehicle model. Compare your results to the manufacturer specifications. You may find the specification in your vehicle repair manual. If out of specification, replace the sensor.
Can you ohm test a cam sensor?
Testing its electrical resistance with an ohmmeter or multimeter allows you to troubleshoot the cam sensor. Cam sensor resistances and the location of the sensor vary with your vehicle’s make and model.
How to test the camshaft position sensor on a Volvo?
I am testing the camshaft position sensor with a meter plugged into the connector that goes to the ECU. This is according to the test procedure by Chilton, Hayes, and Volvo. It calls for testing the values at the harness on the engine side unplugged from the sensor. I do not have an account with Alldata. I have pulled a P0340 code.
Can a faulty camshaft sensor cause a Volvo V70 to stall?
In this tech article we will go about testing Volvo V70 camshaft position sensors on base V70 models. Other engines are similar, and the same test techniques can be applied. A faulty camshaft sensor will set a fault code and possibly create engine drivability problems such as rough idle, engine stalling and misfire.
What’s the sensor shutter position on a Volvo V70?
Pin 2 5 or 0 volts (depending on sensor shutter position), Pin 3 Ground, around zero volts. Steer the wheels all the way right. Then working in the wheel well, remove the 10mm plastic nut (red arrow). Open the plastic access cover (red arrow) to gain access to the crankshaft pulley (green arrow).
What should the DVOM be on a Volvo V70?
Monitor the DVOM. The voltage should fluctuate just as it should when rotating the engine by hand. In this photo the wrench (red arrow) is away from the sensor (green arrow), so the DVOM reads 0 volts. In this photo the wrench (red arrow) is close to the sensor (green arrow), so the DVOM reads 5 volts.
