What is a intake camshaft position sensor replacement?

The cylinder head of your car's engine has either one or two camshafts that operate the intake and exhaust valves. The crankshaft drives the camshaft. To do its job, the crankshaft uses gears, a timing belt or a timing chain. The camshaft position sensor monitors the position of the rotating camshaft relative to the position of the crankshaft. Based on this information, it adjusts the spark timing and fuel injector operation. Note that the camshaft position sensor is different from the crankshaft position sensor.

How is a intake camshaft position sensor replacement done?

In some vehicles, replacing the CMP sensor is as easy as unplugging the electrical connector, unscrewing the mounting bolt, removing the old sensor, and installing the new one. Other models may require the removal of one or more other associated parts before you can access the sensor.


If you're within easy range of your home or office, we recommend you give us a call as soon as practical after you see the engine light go on. We'll come out, diagnose the problem, and give you a firm price quote. Once you're happy with the quote, our mechanics will replace the camshaft position sensor right then and there while you go ahead and do what you were going to do anyway.

Can I do it myself?

Once your car's computer has triggered the engine light, you can retrieve the diagnostic trouble code (DTC) using a code reader or a scan tool. The DTC is a generic code used by vehicle manufacturers to identify problems. If you don't have a code reader, you can your car to a nearby garage or auto parts supply store that will retrieve the code without charging you for it. The procedure itself is simple enough but it may require the use of expensive diagnostic scopes and scanners that you may not have lying around in your garage or workshop. Let us do it.

Safety: Can I drive without doing an intake camshaft position sensor replacement?

It's not a pull-over-to-the-side-of-the-road and flag down help kind of emergency. You will want to get it fixed as soon as practical after you see the engine light go on, otherwise, it may later turn into that kind of emergency. Also, you want to replace the sensor before you damage any other parts of your car.
