What does the p0340 Jeep camshaft position sensor do?
P0340 JEEP Description. The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection.
What should I do if my Jeep Grand Cherokee p0340 fails?
These include the PCM failing or the Crank Sensor failing. You’ll need to check the voltage at the camshaft sensor to see if it is within spec. P0340 is a serious concern and should be addressed as soon as possible. We recommend taking your Grand Cherokee into a mechanic as soon as possible.
What causes the p0340 CMP sensor to malfunction?

What is the camshaft sensor code on a Jeep Grand Cherokee?
My 2011 Grand Cherokee V6 has a check engine light with the Camshaft Position Sensor code (P0340). The car goes into limp mode now when the light comes on, but it has cleared on its own before.
What causes the p0340 code on a jeep?
Jeep Grand Cherokee P0340 Causes As stated above, the P0340 code is often caused by a failure in the Camshaft Position Sensor itself. Here are the most common causes: Wiring Issue – The Camshaft Position Sensor wiring is exposed to harsher conditions than a lot of the wiring in your Grand Cherokee.
What causes a camshaft position sensor error p0340?
Error P0340 is associated with a malfunctioning camshaft position sensor. The sensor plays a vital role in detecting the rotational speed of the camshaft and relaying this information to the PCM. The PCM then determines the opening and closing of the intake valves. It will also determine the right timing for ignition.

What does the p0340 code mean on a PCM?
Camshaft sensors: The most common problem related to the P0340 code is actually broken Camshaft sensors. Sensors on the camshaft collect information and relay this to the PCM. This then influences the timing of air and fuel into the combustion chamber.
