Nissan Maxima Camshaft Position Sensor

Frequent Fuss of a Bad Nissan Maxima Camshaft Position Sensor

Although very uncommon, a failure of the camshaft position sensor does happen. Moreover, it causes a variety of problems, mainly bringing performance issues. Camshaft position sensors do an important job of communicating signals from the combustion chamber to the computer of the vehicle in order to ensure efficient operation. These sensors do have moving parts that are susceptible to failure if not taken care of. Below are some of the frequent fuss on bad camshaft position sensors that can happen to your Nissan Maxima.

Hard starting

If the camshaft position sensor is not working properly, the engine will have either a hard time starting or not start at all. This is because of its function as a messenger to the ignition module or the electronic control module (ECM). The engine might experience extended warm up times because of this problem. Without the proper signal, the respective modules won't be able to act upon the command you are giving, in this case: starting the car. Spark plugs won't fire. Thus, there won't be any combustion.

Engine hesitation

While idling or accelerating, the engine will hesitate to give power once the camshaft position sensor goes bad. The engine will frequently stall because of erratic feeds shot by the camshaft position sensor to the electronic control module. This messes up the timing of the spark plugs, when to ignite or stay at rest. The response upon pressing the gas pedal will be unpredictable. Because of this irregularity, other car parts will experience another load of stress they never felt before. As a result, they will be at risk of breaking down earlier than expected.

Misfires and stalling

A faulty camshaft position sensor also makes the engine misfire then stall frequently. This is the result of the engine cylinders blowing combustion through the exhaust. That causes a load sound, followed by stalling, as if the engine is going to die. Again, this one is a timing issue owed to the miscommunication or wrong information dealt by the bad camshaft position sensor to the ignition module. Timing is essential because the correct order of firing for each cylinder contributes to the efficiency and smoothness of the engine.

  • Ways to Keep Your Nissan Maxima Camshaft Position Sensor in Top Shape 04 March 2014

    Have you ever wondered that even after so many miles, the timing of the engine never messes up? Even after other parts fail, the timing is rarely ruined because of the camshaft position sensor. This is the part that provides the camshaft position information, commonly known to mechanics as CMP signal. This is, in turn, is used by the powertrain control module (PCM) for fuel synchronization. Once this little component goes bad, headaches are sure to ensue. Therefore, proper maintenance is essential for your Nissan Maxima camshaft position sensor.

    • Open the lines of communication.
    • It is a known fact that the failure to communicate leads to ruined relationships. This same principle also applies to the camshaft position sensor. Having this component means there are no distributors. This is better because there won't be any need for traditional maintenance of replacing the points or the rotors. And since it uses signals to control the timing of the ignition, the lines of communication (in this case: the sensor harness wires), should be kept open. Make sure that they are tightly connected and in good condition.
    • Test your camshaft position sensor.
    • The camshaft position sensor operates under the principle of magnetic induction, much like an alternator. When a magnetic field is introduced to a conductor, it produces a current or voltage. This will allow the gear to turn on the camshaft. The result of this physics lesson is an A/C sine wave voltage that is interpreted by the onboard computer to determine the cylinder positions. If there is a variation in the signal, the engine computer won't give out the proper response or even stop responding to the camshaft position sensor. Remember to use a multimeter to test the sensor and set it to ohms. Turn to your owner's manual to determine the specified range of resistance that the sensor has to have in order to work properly. Test the wires also. The wires deliver power to the camshaft position sensor. A reading of greater than 10.5 volts means the sensor is getting enough power.
    • Clean the camshaft position sensor.
    • Because the camshaft position sensor lies within the nooks and crannies of an engine, it can be sputtered with oil or grime at times. It's a good thing that the camshaft position sensor can be cleaned. Just spray a small amount of solvent on the sensor and let it sit until the solvent works its magic. Wipe it dry before putting it back because parts that are powered with electricity don't fare well when wet. Spray some WD-40 on the screws for good measure too.
