What causes an OBD code for a camshaft sensor?
Typically the causes for this code are: Intermittent open in the power supply circuit to the camshaft position sensor Intermittent short to ground in the power supply circuit to the camshaft position sensor Intermittent open in the ground circuit to the camshaft position sensor Intermittent open in the signal circuit to the camshaft position sensor
Why do I need to change the camshaft position sensor?
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. The P-0340 trouble code indicates that the signal to and from the camshaft position sensor and the PCM is broken.
How much does a bad camshaft sensor cost?
In this case, because of an inaccurate reading from a bad camshaft position sensor, more fuel than necessary is injected into the engine which causes your fuel economy to drop. To replace a camshaft position sensor, you can expect to pay anywhere from $120 to $300. Parts alone will run about $50 to $200.
What do sensor A and B codes mean?
Sensor A indicates that the malfunction is occurring with the camshaft position sensor circuit that pertains to the intake camshaft. Sensor B codes pertain to the exhaust camshaft. What are the common causes of code P0340?

When do I need to replace the Ol measure sensor?
Of course, a meter reading of OL measure there is an open in the sensor and it should be replaced. Next, crank the engine and watch the ohmmeter – the reading should fluctuate. You can also do this with your meter set to read AC voltage. If there is no change in the reading, the sensor is bad and should be replaced.
Where is the CMP sensor on the engine?
The camshaft position sensor reacts to a toothed wheel on the camshaft, which gives the ECU constant information on its speed and position. 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.
What does Bank 2 on a camshaft position sensor mean?
Camshaft Position Sensor A Circuit Intermittent (Bank 2) What does that mean? This is a generic powertrain diagnostic trouble code (DTC), which means it covers all makes/models starting around 2003. The code seems more common on Dodge, Chrysler, Ford, Honda, Jeep, BMW, and Acura vehicles, but any make vehicle can be affected.
What does a bad camshaft position sensor code mean?
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). IV. CMP Codes and What They Mean
What should I use to test my camshaft sensor?
When you are disconnecting the battery’s terminals, the half-inch wrench will help unscrew the nuts. Get yourself a digital volt ohmmeter or a digital multimeter from any hardware shop, which will help you measure the resistance or voltage in your camshaft sensor. So that you know if something seems wrong.
What does no spark on camshaft sensor mean?
No spark means that the engine will not start at all, indicating that the camshaft sensor has failed. Newer cars will detect that the camshaft position sensor is not functioning properly, then they will use the crankshaft position sensor instead.
Can a faulty camshaft sensor cause a knocking sound?
Question: Can a faulty camshaft sensor cause a knocking sound? Answer: No, a faulty camshaft sensor can’t cause a knocking sound unless it affects ignition timing. Question: Can a faulty camshaft sensor cause a P0300 code? Answer: A number of faulty components may trigger a P0300 code, including: a bad camshaft position sensor
