P0349 2009 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 2009 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 2009 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
How to Fix the DTC P0349 2009 Ford Fusion?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0349 2009 Ford Fusion Code
1. What does the OBDII code P0349 mean on a 2009 Ford Fusion?
P0349 indicates an intermittent issue with the Camshaft Position Sensor 'A' Circuit on Bank 2, which could affect the timing and performance of the engine.
2. What are the symptoms of code P0349 in a 2009 Ford Fusion?
Common symptoms include rough idling, decreased fuel efficiency, stalling, difficulty starting the engine, or the Check Engine Light illuminating.
3. What causes the P0349 code in a 2009 Ford Fusion?
Possible causes include a faulty camshaft position sensor, damaged or corroded wiring in the sensor circuit, a malfunctioning timing chain or belt, or a bad PCM (Powertrain Control Module).
4. Can I drive my 2009 Ford Fusion with a P0349 code?
It is not recommended to drive with this code for an extended period, as it can lead to engine performance issues and potentially cause further damage.
5. How do you diagnose the P0349 code?
Diagnosis typically involves using an OBDII scanner to confirm the code, visually inspecting the camshaft position sensor and its wiring, and checking the timing components for wear or damage.
6. How do you fix the P0349 code on a 2009 Ford Fusion?
Repairs might include replacing the camshaft position sensor, repairing or replacing damaged wiring, inspecting and adjusting the timing chain or belt, or, in rare cases, reprogramming or replacing the PCM.
7. Where is the Bank 2 Camshaft Position Sensor located on a 2009 Ford Fusion?
Bank 2 refers to the side of the engine opposite Bank 1. For a V6 engine, this would typically be the side without cylinder 1. The sensor is usually located near the camshaft on that side.
8. How much does it cost to fix code P0349 on a 2009 Ford Fusion?
Repair costs can range from $100 to $300 for a camshaft position sensor replacement. Additional repairs, such as fixing wiring or timing components, may increase costs.
9. Can a bad timing chain cause the P0349 code in a 2009 Ford Fusion?
Yes, a stretched or worn timing chain can cause improper camshaft timing, leading to intermittent signals from the camshaft position sensor and triggering the P0349 code.
10. What tools are needed to fix the P0349 code on a 2009 Ford Fusion?
Common tools include an OBDII scanner, a multimeter for testing wiring, basic hand tools for sensor replacement, and possibly timing tools if the timing chain or belt requires adjustment.
