Camshaft Position Sensor A Circuit

In this way the magnetic field can cause the voltage from the sensor to change.

Camshaft position sensor a circuit.

If the ecu cannot detect a cmp signal it will set dtc p0340 or dtc p0345 camshaft position sensor circuit malfunction. The camshaft position sensor reacts to a toothed wheel on the camshaft which gives the ecu constant information on its speed and position. The camshaft position sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. On this page you can find out how a fault on the camshaft sensor can manifest itself and which steps should be taken during troubleshooting.

Sensor a indicates that the malfunction is occurring with the camshaft position sensor circuit that pertains to the intake camshaft. This information is used by the engine control module ecm to control ignition and fuel injection. Once the engine is running the low and high parts of the teeth cause the gap with the sensor to change. If your engine has only one cmp such as an inline four cylinder the only cmp code available is.

It is triggered when the powertrain control module pcm detects a problem with the signal being sent by the camshaft position sensor. Sensor b codes pertain to the exhaust camshaft. These codes differ in terms of how long the problem persists and the type of problem that the sensor circuit or engine controller experiences. This is one of the reasons why the changing gap causes the magnetic field near the sensor to change.

Apart from this the sensor system consists of actual sensor static part and rotating part. On the other hand v6 or v8 engines have two banks bank 1 and bank 2 and would therefore have two cmps so dtc p0346 would refer to bank 2. Specifications on the definition troubleshooting and repairs of course vary from one make and or model to another. This information is required to calculate the ignition point and injection point among other things.

When the crankshaft. Of course the cmp is located on the engine usually somewhere on the cylinder head so it transmits cmp data to the ecu using wires. This means the cmp camshaft position sensor circuit on engine bank 1 sends an irregular reading. In addition to this the camshaft position has the ability to sense the piston position.

It s a generic trouble code meaning it applies to all vehicles equipped with obd ii particularly vehicles made since 1996 up to present. The camshaft sensor is located in the cylinder head and reads the camshaft sprocket to determine the position of the camshaft. However specific troubleshooting steps will vary depending on the vehicle. Camshaft position sensor a circuit low bank 1 what does that mean.

Other trouble codes such as p0340 camshaft position sensor a circuit and p0341 camshaft position sensor a circuit range performance may get logged at the same time as the code p0344. The cmp works by sending. The automotive trouble code p0342 is one of several generic malfunction codes relating to the camshaft position sensor cps. The camshaft position sensor senses the retraction of camshaft intake to identify a particular cylinder.
