P0340 Camshaft Position Sensor A Circuit

Definition the cps is an electronic device that is usually utilized in an engine to easily and quickly record the rate at which the camshaft is spinning.

P0340 camshaft position sensor a circuit.

This sensor requires a series of electrical connectors and wiring to function properly so there could be many trouble points throughout the system. 3 1 the electronic circuit camshaft position sensor circuit the camshaft position sensor used in kia rio 2010 is the hall effect type. The changing gap causes the magnetic field near the sensor to change. Camshaft position sensor circuit malfunction.

The sensor system consists of a rotating part typically a disc as well as a static part the actual sensor. P0340 meaning the camshaft position sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. The camshaft sensor sends a signal to the power control module pcm to communicate this information. The camshaft position sensor calculates the rotational speed of the camshaft and where the camshaft is positioned in that rotation.

If the ecu cannot detect a cmp signal it will set dtc p0340 or dtc p0345 camshaft position sensor circuit malfunction. It is mounted at the end of the intake camshaft see fig. The camshaft position sensor senses the piston position. This p0340 code indicates that a problem was detected in the camshaft position sensor circuit.

What the p0340 code means. Make any other repairs if other codes are present to make sure that other codes are not sources of the trouble code p0340. P0340 description the camshaft position sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. Camshaft position sensor circuit malfunction.

Don t just replace the cps camshaft position sensor and think that will definitely fix it. This information is used by the engine control module to control ignition and fuel injection the camshaft position sensor senses the retraction of camshaft intake to identify a particular cylinder. If your engine has only one cmp such as an inline four cylinder the only cmp code available is for bank 1 p0340. Since it says circuit that means the problem could lie in any part of the circuit the sensor itself the wiring or the pcm.

Visually inspect the camshaft position sensor connector in search of corroded or broken connectors. Since the circuit is a concern the problem could be in any component of the circuit such as pcm wiring and sensor itself. This information is used by the engine control module to control ignition and fuel injection the camshaft position sensor senses the retraction of camshaft intake to identify a particular cylinder. When the engine is running the high and low parts of the teeth cause the gap with the sensor to change.

When the camshaft timing pin comes close to the sensor head the voltage at the signal wire drops to zero.
