What does Error Code P0345 mean?
Moderate Issue
DTC Code P0345 indicates a malfunction in the Camshaft Position Sensor 'A' Circuit on Bank 2. This code is triggered when the Engine Control Module (ECM) fails to detect the camshaft position sensor signal during initial engine cranking.
What are the symptoms of Error Code P0345?
- Engine Light ON: The check engine light or service engine soon warning light illuminates, indicating a malfunction in the camshaft position sensor 'A' circuit on bank 2.
- Lack/Loss of Power: The vehicle may experience a noticeable reduction in power, which can be linked to the camshaft position sensor's inability to provide accurate data to the engine control module.
- Engine Stall: The engine may stall unexpectedly, which can be attributed to the camshaft position sensor failing to send the correct signals, disrupting the engine's timing and operation.
What causes Error Code P0345?
- The camshaft position sensor may be faulty, leading to incorrect readings and triggering the error code.
- An open or shorted harness in the camshaft position sensor can disrupt the signal, causing a malfunction.
- Poor electrical connections in the camshaft position sensor circuit can result in intermittent or failed communication.
- A faulty starter motor can affect the engine's ability to start, indirectly impacting the camshaft position sensor's operation.
- Issues within the starting system circuit can lead to insufficient power reaching the camshaft position sensor.
- A dead or weak battery can cause inadequate voltage supply, affecting the sensor's performance.

How to fix Error Code P0345?
- Verify Battery Voltage: Check the battery voltage to ensure it is within the manufacturer's specifications. Low voltage can affect sensor readings.
- Inspect Camshaft Position Sensor: Visually inspect the Camshaft Position Sensor 'A' on Bank 2 for any signs of damage, corrosion, or loose connections.
- Check Wiring and Connectors: Examine the wiring and connectors leading to the Camshaft Position Sensor for any signs of wear, damage, or disconnection.
- Test Sensor Signal: Use an oscilloscope to test the signal from the Camshaft Position Sensor to ensure it is producing the correct waveform.
- Inspect Starter and Charging System: Evaluate the starter and charging system for any issues that could lead to low voltage, which might trigger the code.
- Check Engine Timing: Verify that the engine timing is correct, as incorrect timing can affect the camshaft position sensor readings.
- Perform ECM/PCM Scan: Scan the Engine Control Module/Powertrain Control Module for any additional codes that might provide further insight into the issue.
