James

James did a great job replacing my radiator. He called to see if he could come a little early which worked out great. He was very professional, cleaned everything up after he was all done. Asked if I had any question about anything on my car and gave me a few pointers about an issue I was having with my hood shocks. I will for sure be calling him again when I need any service done to my car. I have already recommended him to 3 of my friends looking to get some work done on their cars.

All about Camshaft Position Sensor Replacement

The camshaft position sensor monitors the position of the camshaft and reports that data to the car’s onboard computer system. This computer system works with sensors and other devices to keep the engine running. With data from the camshaft position sensor (CPS), the fuel injectors know when to fire. When the sensor malfunctions, the computer does not know when to fire the injectors and may not fire them at all. The faulty readouts may also throw off spark timing, which will affect the car’s fuel economy. This sensor is used in conjunction with the crankshaft position sensor to control ignition timing. It is common for heat and oil leaks to cause this sensor to fail, due to where the sensor is located.
