You may need a compression test and leak down test to diagnose the problem. So most likely there's a leak at the cylinder wall, rings, valve or head gasket. The white smoke is more related to coolant or oil leaks (bluish smoke) into the combustion chamber. Remove the sensor and inspect it for signs of physical damage or contamination.Īnswer: The CAM tells the computer the position of the camshaft, and works in sync with the crankshaft sensor, so the computer knows when to fire an injector (depending on model) and to fire spark.If the voltage signal is lower than the specification, or no signal comes out of the sensor, most likely the sensor is bad. Compare your reading to the specification in your vehicle repair manual. Touch the signal wire with the red probe from your meter and the ground wire with the black probe.Compare your reading to the specification in your manual. Touch the black probe on your meter to ground (a metal bracket, bolt, or metal surface on the engine itself) and the other probe to the power wire.Have an assistant turn the ignition key on, but don't start the engine.Once you identify the power, ground, and signal wires using your vehicle repair manual, test the sensor's circuit by setting your multimeter to "DC volts.".If there's no signal, you have a bad CMP sensor.In most cases, you'll see a fluctuating signal between 0.3 volts and 1 volt. #2001 DODGE NEON DRIVE SHAFT SENSOR LOCATION MANUAL#Check your meter display and compare your reading to your manual specifications. Touch one of your meter probes to either one of the sensor wires and the other probe to the other wire.Have your assistant crank or start the engine.If neither wire has current, there's a failure in the sensor's circuit. Touch one of your probes to ground (any metal part on the engine) and the other probe to each one of the sensor wires. Check for the presence of power flowing through the circuit.Have an assistant turn the ignition key on without starting the engine.If you have a two-wire, magnetic-type CMP sensor, set your multimeter to "AC volts.".If you use this last method, use electrical tape to cover the pin holes on the wires' insulation after you're done with your tests to prevent corrosion from creeping into the wires. Another testing solution is to pierce through each wire using a pin, being careful not to short out the wires during your tests.Then plug the connector back in so that the two strands stick out through the connector's housing. If this isn't possible, see if you can unplug the sensor connector and attach a strand of copper wire to each terminal on the connector.With some sensors, you may back-probe the wires through the sensor electrical connector.You may find this information in your vehicle repair manual. You'll also need the correct electrical values for your particular type of sensor. After these checks, use a digital multimeter that can test either alternate current (AC) voltage or direct current (DC) voltage, depending on your particular type of camshaft position sensor. Also, make sure the sensor wires are not touching spark plug wires or ignition coils, which may interfere with the sensor's signal. Then check for wire damage: broken wires, loose wires, and signs of burns caused by nearby hot surfaces. Unplug the connector and check for rust or contamination, like oil, that is interfering with good electrical contact. First, check the condition of the sensor's electrical connector and wires.I highly recommend that you buy an aftermarket repair manual for your specific vehicle make and model ( Haynes is a good inexpensive brand) for reference when doing maintenance and small repairs. You may find a copy in the reference section of your local public library. If you need help finding the sensor(s), check the vehicle service manual for your particular model. #2001 DODGE NEON DRIVE SHAFT SENSOR LOCATION SERIES#Some GM models may have a special compartment for the sensor.Īlso, some Mercury Villager and Nissan Quest models locate the CMP sensor inside the distributor housing, as well as some Dodge Ram B1500, B2500, and B3500 series models with gasoline engines.ĭepending on the specific model of your car, your engine may have one or more cam sensors. Look around the top section of the timing belt/chain cover (in the front of the engine) or at the rear end of the cylinder head. On most models, you can find the sensor somewhere around the cylinder head. As you may expect, the specific location of the camshaft position sensor varies by a vehicle's make and model.
