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.
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.
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.
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.
