P0347 2010 Toyota Camry Code - Camshaft Position Sensor 'A' Circuit Low Input Bank 2

The P0347 code indicates a "Camshaft Position Sensor 'A' Circuit Low Input" on Bank 2, meaning the ECM is detecting a weak or no signal from the camshaft position sensor.

Symptoms include engine misfires, rough idling, reduced power, difficulty starting, poor fuel economy, and potentially the engine stalling.

Common causes include a faulty camshaft position sensor, damaged or corroded wiring, a poor electrical connection, a failed ECM, or a timing issue such as a stretched timing chain.

P0347 refers to the camshaft position sensor 'A' on Bank 2, which monitors the camshaft's position and timing on the side of the engine opposite Bank 1.

Start by checking the sensor wiring for damage or corrosion, test the camshaft position sensor with a multimeter, and inspect the timing components for misalignment.

Driving with P0347 is not recommended as it can cause poor engine performance, increased emissions, and potential damage to internal engine components.

Repairs may involve replacing the camshaft position sensor, repairing or replacing damaged wiring, cleaning electrical connections, or addressing timing chain issues if necessary.

The difficulty depends on its location, but it is generally accessible with basic tools. Consult the vehicle's repair manual for step-by-step guidance.

You'll need a diagnostic scanner, multimeter, basic hand tools (like sockets and ratchets), and possibly a repair manual for your vehicle.

Costs vary depending on the repair; replacing the camshaft position sensor can cost $100-$300, while fixing wiring or timing issues may be more expensive.
