P0349 2012 Ford Fusion Code - Camshaft Position Sensor 'A' Circuit Intermittent Bank 2

P0349 indicates an intermittent issue with the Camshaft Position Sensor 'A' circuit on Bank 2, which can affect engine timing and performance.

Symptoms may include rough idling, engine stalling, reduced power, difficulty starting, and the check engine light illuminating.

Common causes include a faulty camshaft position sensor, damaged wiring or connectors in the sensor circuit, a failing timing chain or belt, or issues with the engine control module (ECM).

Driving with this code is not recommended, as it can lead to poor engine performance, potential stalling, and further damage to engine components.

Repairs may involve replacing the camshaft position sensor, repairing damaged wiring or connectors, inspecting the timing chain or belt, or reprogramming the ECM if necessary.

A faulty sensor can be identified through diagnostic testing, which may show irregular or no signal from the sensor when monitored with a scan tool.

In the 2012 Ford Fusion, Bank 2 is typically the side of the engine opposite the number 1 cylinder, and the sensor is mounted near the camshaft of that bank.

Yes, a stretched or misaligned timing chain can cause intermittent camshaft position signal issues, triggering the P0349 code.

You’ll need an OBDII scanner, a multimeter to check wiring and sensor signals, and possibly specialized tools to inspect the timing chain.

The cost varies depending on the issue, but replacing the camshaft position sensor typically costs $100–$300, while timing chain repairs can exceed $1,000.
