Code P0347 Scion Description

The P0347 code for a Scion indicates that there is a low input signal detected from the camshaft position sensor 'A' in bank 2. The camshaft position sensor plays a crucial role in the engine's operation by monitoring the position of the camshaft and sending this information to the engine control module (ECM). The ECM uses this data to control fuel injection timing and ignition timing. A low input signal from the camshaft position sensor can lead to issues with engine performance, fuel efficiency, and emissions.
