Why does my cam sensor keep going bad?
The issue is likely a bad wire in the wiring harness. Open the hood and shake the wires for the cam position sensor while the engine is running, in fact, shake the whole harness between the sensor and engine control module. You want to see if it hiccups when you move, shake, bend a certain section.
Can I drive with a P0340 code?
A P0340 code spells bad news for any vehicle. Drivers may find it difficult or impossible to start the engine because of the resulting engine performance problems. If they persist in operating the vehicle, they may lose power while on the road.
Will crankshaft sensor throw a code?
Answer: Yes. Either a circuit or sensor signal problem can throw a P0340 – P0344 trouble code.
What happens when a camshaft sensor goes bad?
Once your car’s computer detects a CMP sensor failure, it will trigger the engine light and store a diagnostic trouble code (DTC) in its memory (see the table below for common camshaft position sensor trouble diagnostic codes).
How does the camshaft position sensor work in a car?
The engine control unit of the vehicle monitors the camshaft’s rotating position with a component called the “camshaft position sensor.” Based on the information which the sensor transmits, the engine control unit will determine how much fuel should get injected into the combustion chamber and the timing of the spark.
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.
Why does a camshaft sensor have a higher resolution than a timing chain?
It is because the timing chain or timing belt always has a little give and this can obscure the movement of the crankshaft from the camshaft position sensor. Further because the crank shaft is spinning at twice the speed of the camshaft the signal is of a higher resolution.
