What causes a camshaft position sensor code?
The most common cause of the P0343 code is a faulty camshaft position sensor or faulty wires to the camshaft position sensor. A common misdiagnosing of this trouble code is that it could be a faulty timing belt timing that will cause the p0343 code.
What does a cam position sensor do?
The CAM sensor or camshaft position sensor’s role is to signal the ECM the camshaft position. The crank and cam sensor operates in sync with eachother. The CAM sensor is frequently used in determining which injector to fire in a sequential system and for the COP or coil on-plug ignition systems coil firing event.
What is a cam position sensor?
A cam position sensor is a component used to monitor the position of the camshaft. This information is used by the ECM (ECU) to control ignition system timing and other engine parameters.
Where is the camshaft position sensor Bank 1?
SOURCE: P0344 Camshaft Position Sensor A Circuit Intermittent (Bank 1 or. The camshaft sensor is located right above the crankshaft pulley on the passengers side of the front cover of the engine.
What is the trouble code for camshaft sensor Bank 2?
P0390 is a diagnostic trouble code (DTC) for “Camshaft Position Sensor “B” Circuit (Bank 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
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 does the PCM determine the camshaft position?
The PCM determines the position of the two shafts using information from a crankshaft position sensor and camshaft position sensor (s). If from the sensor data, the PCM determines the crankshaft and camshaft (s) are not in sync, it will set code P0016 and turn on the Check Engine Light.
What is the p0344 code for a camshaft sensor?
P0344 Code: Camshaft Position Sensor “A” Circuit Intermittent (Bank 1 or Single Sensor) P0345 Code: Camshaft Position Sensor “A” Circuit (Bank 2) P0122 Code: Throttle Position Sensor/Switch A Circuit Low Input
How is the camshaft position sensor connected to the PCM?
It covers the entire circuit attached to the aforementioned sensor, such as the electric wiring and the powertrain control module (PCM). Thus, replacing the sensor will not always resolve the issue. The camshaft position sensor calculates the speed at which the engine’s camshaft rotates.
What causes the p0340 CMP sensor to malfunction?
P0340 – Camshaft position (CMP) sensor A, bank 1 circuit malfunction Trouble Code Fault Location Probable Cause P0340 Camshaft position (CMP) sensor A, bank 1 Wiring, CMP sensor, ECM
How to fix a bad camshaft position sensor?
Apply a bit of engine oil to the o-ring of the new senor. Install the new camshaft position sensor and secure with the mounting bolt. Reconnect the wire connector to the sensor. Reconnect the negative battery terminal.
Where does the p0340 code get stored in an engine?
P0340 Code: Camshaft Position Sensor – Circuit Malfunction A P0340 Code gets stored in the engine control module when it got a faulty signal from the Camshaft position sensor. There are some possible causes of this, and in this article, you will learn how to diagnose it properly.
What does the p-0340 trouble code mean?
The P-0340 trouble code indicates that the signal to and from the camshaft position sensor and the PCM is broken. When this occurs, the ignition spark and fuel injector timing will fail and the PCM will store the P0340. This will trigger the illumination of the Check Engine Light.
Where is the p0340 sensor located on a Ford Edge?
See the section on Common Causes for more details on other possible causes of code P0340 on Ford vehicles. Where is the P0340 sensor located? This image shows the location (circled) of the camshaft position sensor on a 2015 to 2019 Ford Edge.
What is the OBD code p0340?
OBD-II Code P0340 is defined as a Camshaft Position Sensor “A” Circuit Malfunction The Camshaft Position Sensor measures the exact rotational position of the camshaft. Aug 12 2019
What does the code p0340 mean?
P0340 is a diagnostic trouble code (DTC) for “Camshaft Position Sensor Circuit Malfunction”.
What is causing error code p0340?
A faulty power-train control module can cause a P0340 error code as well as several other issues. Alternatively, you might be seeing the P0340 error code due to a variety of shorted, corroded, or otherwise defective sensors. A faulty crankshaft position sensor or camshaft position sensor are the most common culprits.
What does error code p0340 mean?
The error code P0340 simply means that the computer has completely sent a signal to the camshaft position sensor however it does not see the right signal that is being returned from the sensor. Since the circuit is a concern, the problem could be in any component of the circuit such as PCM, wiring and sensor itself.
What does the OBD II fault code p0340 mean?
What Does Code P0340 Mean? OBD II fault code P0340 is a generic code that is defined as “Camshaft position (CMP) sensor “A”, bank 1 – circuit malfunction”, and is set when the PCM (Powertrain Control Module) detects an electrical problem in the control circuit of the camshaft position sensor labelled “A”.
