P0349 2010 Ford Fusion Code - Camshaft Position Sensor 'A' Circuit Intermittent Bank 2
Quick Answer
The test fails when the Powertrain Control Module (PCM) detects an intermittent signal from the camshaft position (CMP) sensor. Common causes include Faulty Camshaft Position Sensor, Camshaft Position Sensor harness is open or shorted, Camshaft Position Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0349 2010 Ford Fusion Description
The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.
When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.
When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.
What are the Possible Causes of the DTC P0349 2010 Ford Fusion?
- Faulty Camshaft Position Sensor
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Variable Cam Timing (VTC) Solenoid
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery

Frequently Asked Questions about P0349 2010 Ford Fusion Code
What does the OBDII code P0349 mean for a 2010 Ford Fusion?
P0349 indicates an intermittent issue with the camshaft position sensor 'A' circuit on bank 2, which is responsible for monitoring the camshaft's position to ensure proper engine timing.
What are the symptoms of code P0349 in a 2010 Ford Fusion?
Common symptoms include engine misfires, rough idling, poor acceleration, reduced fuel efficiency, difficulty starting, and the check engine light turning on.
What causes code P0349 in a 2010 Ford Fusion?
Causes may include a faulty camshaft position sensor, damaged wiring or connectors, a failing timing chain or belt, or issues with the engine control module (ECM).
Can driving with code P0349 damage my 2010 Ford Fusion?
It’s possible. Prolonged driving with this issue may lead to engine misfires or improper timing, which can cause further damage to the engine components.
How do I fix code P0349 in a 2010 Ford Fusion?
Repairs typically involve inspecting and replacing the camshaft position sensor, checking wiring and connectors for damage, and ensuring the timing chain or belt is functioning properly.
Where is the camshaft position sensor 'A' located on a 2010 Ford Fusion?
On the 2010 Ford Fusion, the camshaft position sensor is typically located near the camshaft on the engine. Bank 2 refers to the side of the engine opposite to cylinder 1.
How can I test the camshaft position sensor for P0349?
You can use a multimeter or an oscilloscope to check the sensor’s voltage and signal output. If the readings are inconsistent or absent, the sensor may be faulty.
Can a dirty or clogged oil passage cause code P0349?
Yes, insufficient oil pressure or dirty oil passages can affect the camshaft’s operation and cause intermittent issues with the sensor’s readings.
How much does it cost to fix code P0349 on a 2010 Ford Fusion?
The repair cost varies depending on the issue but typically ranges between $100-$300 for sensor replacement. More extensive repairs, such as timing chain issues, can be more expensive.
Does code P0349 require reprogramming of the ECM?
In most cases, reprogramming the ECM is not required, but if the ECM has failed or is not processing signals correctly, it may need to be repaired or replaced.
