Diagnostic and Repair Procedure for Toyota P0348 Camshaft Position Sensor “A” Circuit High Input
Step 1: Start by inspecting the wiring and connectors connected to the camshaft position sensor. Look for any signs of damage, corrosion, or loose connections. If any issues are found, repair or replace the wiring or connectors.
Step 2: Next, check the voltage output of the camshaft position sensor. Using a multimeter, measure the voltage between the signal wire (typically the middle wire) and the ground wire (usually the black wire). It should be within the specified range provided by Toyota. If the voltage is too high, it indicates a high input issue and the sensor needs to be replaced.
Step 3: If the wiring and sensor are in good condition, carefully inspect the toothed wheel on the camshaft. It could be damaged or have missing teeth, causing a high input error. Replace the camshaft if necessary.
Step 4: After completing the above steps, clear any fault codes from the vehicle’s ECM (Engine Control Module) using a diagnostic tool. Then, test drive the vehicle under various conditions to ensure that the high input error is resolved.
Remember to follow Toyota’s repair procedures and guidelines to ensure accurate diagnosis and proper repair of the P0348 Camshaft Position Sensor “A” Circuit High Input.
