Q: Check Engine code p0016

Hi There, As you know, code P0016 relates to the camshaft position sensor. It sounds like the sensor may not have been replaced or is still producing the same problems that one typically will produce when it is not working properly. The camshaft position sensor is a magnetic sensor that monitors camshaft speed to regulate ignition timing and fuel injection timing. It gathers and sends information about the car’s camshaft speed to the car’s electronic control module. This information is used by the computer to further calculate the time of ignition and the timing of fuel injection required by the engine. When this is not working properly, you may experience a drop in power, poor idling, poor fuel mileage and problems starting the vehicle. As the sensor begins to fail and gets worse over time as the signal it provides to the computer weakens. I would recommend having a professional from YourMechanic come to your location to diagnose your camshaft position sensor and provide a second opinion on the condition of your engine.
