Difficulty Level

Tools/Supplies Needed:

• analog multimeter

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 are 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
