What does the p0340 code on a camshaft mean?
One common mistake many people make when they see the P0340 is panicking over a faulty timing chain or belt. The P0340 clearly states that there is an electrical problem in the circuit to the camshaft position sensor. Therefore the P0340 trouble code is not caused by a faulty camshaft timing.
Why is my camshaft position sensor not working?
My car has an automatic transmission. The problem with changing out the camshaft position sensor is that sometimes the issue is actually due to the sensor wiring harness; which might be the reason this OBD-II error code was triggered initially.
What does the p-0340 trouble code mean?
The P-0340 trouble code indicates that the signal to and from the camshaft position sensor and the PCM is broken. When this occurs, the ignition spark and fuel injector timing will fail and the PCM will store the P0340. This will trigger the illumination of the Check Engine Light.
How does the camshaft sensor connect to the PCM?
Check wires: The camshaft sensor connects to the PCM through a set of wires. If these are loose or damaged then there will be problems in information transmission. First, check the wiring on your battery and ensure that all the terminals are tightly in place. Also, check the ground cable between the engine and body.
What to do if your camshaft position sensor says p0340?
Visually inspect the camshaft position sensor connector in search of corroded or broken connectors. Make any other repairs (if other codes are present) to make sure that other codes are not sources of the trouble code P0340. Check your camshaft position sensor’s voltage, ground, and signal readings with a multimeter.
How to test crankshaft and camshaft position sensors?
Here is how you can easily test both your crankshaft position sensor and camshaft position sensor. It’s very important to be able to test these sensor since because they control your ignition and fuel injector pulse and if they fail they could cause a Crank No start condition.
What causes a car to have a p0345 code?
Car is running fine (somewhat) but have P0345 code (cam shaft position sensor). The most common cause of this code is going to be the timing chain and timing gear phasers along with cam solenoids can all cause the problem of cam misalignment. The problem can cause low power, rattles and check engine…
What are the symptoms of an OBD-II scanner error code p0340?
Symptoms of an OBD-II scanner error code P0340 problem also include misfiring, stalling, and other engine and ignition problems. Another common issue is a complete ignition failure. As the computer signal weakens, your vehicle’s camshaft position sensor may prevent your ignition from sparking at all.
