Fix P0368: STEP-BY-STEP diagnostic GUIDE!

The P0368: Camshaft Position Sensor ‘B’ Circuit High (Bank 1) code indicates that the engine control module (ECM) is receiving a higher-than-expected signal from camshaft position sensor B on bank 1. This sensor is responsible for monitoring the camshaft’s position, helping the ECM manage engine timing and fuel injection. A high input signal from the sensor could result from a faulty sensor, wiring issues, or circuit problems.
