    DIY: Volvo 850 T5 Camshaft Sensor Testing & Replacement (Video Tutorials)

    Camshaft Sensor Testing

    Video tutorial on how to test the camshaft sensor of a Volvo 850 equipped with a 5 cylinder. This tutorial was done on a 1996 model. If your vehicle has no spark, hard starts, or is running rough, this could possible be the culprit of the problem.

    Procedure:
    -the plug for the camshaft sensor is located directly under the distributor held in my a metal bracket
    -unplug the harness by depressing the metal retaining clip on the plug and pull straight back
    -once the plug is disconnected, using a multimeter you're able to test the pins for continuity and voltage readings
    -the number of the pin is printed on the rubber portion of the plug in very small lettering
    -determine what your vehicles battery voltage is by testing the vehicle's battery
    -test Pin 1 (ground) for continuity to the ground on the battery
    -test Pin 2, with the key in position 2, should read approximately 5V
    -test Pin 3, with the key in position 2, should read approximately battery voltage
    -turning the key off now, using sewing needles, insert the needles in the backside of the connector on the ecu end to Pin 1 and Pin 2
    -ensure they are connected by testing the continuity
    -connect the plug back to the camshaft position sensor
    -an analog multimeter is required for this job because the voltage pulse will not read accurately on a digital meter
    -touching the test probes on the exposed needle ends, have someone turn the engine over and watch for a pulsating voltage
    -the voltage should read approximately 5V, similar to what Pin 2 reading was earlier on in the tests
    -if there is no faults with the previous voltage tests, but there is a weak or no signal voltage, the camshaft sensor is faulty
    -having the probes touching each of the exposed needle ends
