Camshaft Position Sensor A Circuit Low Input B1

This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

Camshaft position sensor a circuit low input b1.

If the ecu detects a low resistance short circuit it will set dtc p0342 or dtc p0347 camshaft position sensor low input. Bank 1 represents the bank of the engine that contains the number one cylinder. Camshaft position sensor a circuit high input bank 1 what does that mean. The p0343 code is a bit tricky yes the high input can in rare cases be caused by a faulty timing.

It s a generic trouble code meaning it applies to all vehicles equipped with obd ii particularly vehicles made since 1996 up to present. 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 position sensor senses the piston position. The signal is low enough to be vague and difficult to interpret.

Description and correlation of the crankshaft and camshaft position sensors. The pcm uses input signals from the camshaft sensor s and the crankshaft sensor to monitor the position and revolutions per minute. The sensor system consists of a rotating part typically a disc as well as a static part the actual sensor. The code seems more common on vw kia hyundai chevrolet toyota and ford vehicles but any make vehicle can be affected.

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. P0342 is a diagnostic trouble code dtc for camshaft position sensor circuit low input. The changing gap causes the magnetic field near the sensor to change. If your engine has only one cmp such as an inline four cylinder the only cmp code available is for bank 1 p0342.

This means the cmp camshaft position sensor circuit on engine bank 1 sends an irregular reading. 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. But for most of the times it s a faulty circuit either caused by a faulty camshaft sensor a wiring issue or the engine control unit. In this instance code p0342 infers the sensor s signal is to low or not strong enough.

P0342 refers to the bank 1 a sensor. On the other hand v6 or v8 engines have two banks bank 1 and bank 2 and would therefore have two. When the engine is running the high and low parts of the teeth cause the gap with the sensor to change. Bank 1 is the side of the engine that contains cylinder 1.
