P0347 2009 Toyota Camry Code - Camshaft Position Sensor 'A' Circuit Low Input Bank 2

P0347 indicates a "Camshaft Position Sensor 'A' Circuit Low Input" on Bank 2, meaning the engine control module (ECM) has detected a low voltage signal from the camshaft position sensor.

Symptoms may include difficulty starting the engine, rough idling, reduced fuel efficiency, engine misfires, stalling, or the Check Engine Light being illuminated.

Potential causes include a faulty camshaft position sensor, damaged wiring or connectors, a short circuit in the sensor circuit, issues with the timing chain or belt, or a malfunctioning ECM.

Use an OBDII scanner to confirm the code, inspect the camshaft position sensor and its wiring for damage, check the timing chain or belt for alignment issues, and test the voltage and signal output of the sensor.

The camshaft position sensor 'A' for Bank 2 is typically located near the front of the engine, on the cylinder head corresponding to Bank 2 (the side opposite the #1 cylinder).

While the car may still run, driving with this code can lead to poor performance, potential engine damage, or unsafe driving conditions. It's best to address the issue promptly.

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

Costs vary but typically range from $100 to $300 for parts and labor to replace the camshaft position sensor, depending on location and labor rates.

While uncommon, a weak or failing battery can cause electrical issues that might affect the camshaft position sensor signal, so it's worth checking the battery voltage.

Ignoring the code can result in worsening performance, increased fuel consumption, potential damage to the engine or catalytic converter, and failure to pass emissions testing.
