Navigating car troubles can be overwhelming, especially when faced with the OBD, ‘s P0345 code. This code, often accompanied by the check engine light, indicates a problem with your car’s camshaft position sensor circuit A, bank 2.
The camshaft position sensor plays a crucial role in synchronizing the engine’s operation by providing data on the position of the camshaft to the engine control module (ECM). A malfunction in this sensor or its circuitry can lead to various symptoms, including rough idling, engine misfires, decreased performance, and stalling.
Diagnosing and fixing the underlying issue causing the P0345 code may involve inspecting and testing the camshaft position sensor, checking related wiring and connectors for damage or corrosion, and verifying the proper alignment and installation of the sensor.
In this guide, we’ll cover all the details of the DTC P0345 code to help you better understand and address the issue.
DTC CODE: P0345 CODE DESCRIPTION: Camshaft Position Sensor “A” Circuit (Bank 2)
What does the P0345 code mean?
The P0345 code is a diagnostic trouble code (DTC) of OBD-II that is commonly encountered in vehicles equipped with onboard diagnostics. It specifically indicates a problem with the camshaft position sensor circuit A, bank 2. This sensor is responsible for monitoring the position of the camshaft(s) in relation to the crankshaft, providing crucial information for the engine control module (ECM) to ensure proper fuel delivery and ignition timing.
When the ECM detects an issue with the camshaft position sensor circuit A, bank 2, it triggers the P0345 code and illuminates the check engine light on the vehicle’s dashboard. Symptoms associated with this code may include rough idling, engine stalling, or decreased engine performance.
Common causes of the P0345 code include faulty camshaft position sensors, wiring issues in the sensor circuit, or problems with the ECM itself. Diagnosing and repairing the underlying cause of the code may require the use of specialized diagnostic tools and equipment.
If you encounter the P0345 code in your vehicle, it is important to address it promptly to prevent potential damage to the engine and ensure optimal vehicle performance. Consulting with a qualified mechanic or technician can help you accurately diagnose and resolve the issue, restoring your vehicle’s reliability and efficiency on the road.

What does the Camshaft Position Sensor “A” Circuit (Bank 2) mean?
The Camshaft Position Sensor “A” Circuit (Bank 2) refers to a specific component in a vehicle’s engine system responsible for monitoring the position of the camshaft in relation to the crankshaft. In modern engines, there are often multiple camshaft position sensors, designated as “A” and “B,” and they are divided into different banks, usually bank 1 and bank 2.
Bank 2 typically refers to the side of the engine where cylinder number 2 is located. So, when the code specifies Camshaft Position Sensor “A” Circuit (Bank 2), it means there is an issue with the camshaft position sensor located on the Bank 2 side of the engine.
The camshaft position sensor plays a crucial role in ensuring proper engine performance by providing data to the engine control module (ECM) about the camshaft’s position. This information is essential for the ECM to determine the precise timing of fuel injection and ignition spark.
When there’s a problem with the Camshaft Position Sensor “A” Circuit (Bank 2), it can lead to various engine performance issues, such as rough idling, poor acceleration, or even engine stalling. Diagnosing and repairing the issue typically involves inspecting the sensor, its wiring, and related components to identify and address the underlying cause.

What are the Possible Causes of the P0345 Code?
The P0345 code, which indicates a malfunction in the camshaft position sensor circuit A, bank 2, can be triggered by several potential issues within the vehicle’s engine system. Common causes of the P0345 code include:
- Faulty Camshaft Position Sensor: The sensor itself may be malfunctioning or failing to accurately detect the position of the camshaft.
- Wiring Issues: Damage, corrosion, or poor connections in the wiring harness connected to the camshaft position sensor can disrupt the signal transmission, leading to the P0345 code.
- Sensor Alignment: If the camshaft position sensor is misaligned or improperly installed, it may not accurately detect the camshaft’s position, triggering the code.
- Engine Timing Problems: Issues with the engine’s timing chain or timing belt can affect the synchronization between the camshaft and crankshaft, leading to erroneous readings from the camshaft position sensor.
- ECM Malfunction: A malfunctioning engine control module (ECM) may not properly interpret signals from the camshaft position sensor, resulting in the P0345 code being triggered.
- Mechanical Engine Issues: Damage or wear to components such as the camshaft, camshaft gear, or camshaft phaser can also affect the performance of the camshaft position sensor and trigger the P0345 code.

What are the Common Symptoms of the P0345 Code?
The P0345 code, signaling a malfunction in the camshaft position sensor circuit A, bank 2, can manifest through various noticeable symptoms in a vehicle. Common indicators of the P0345 code include:
- Rough Idle: One of the most common symptoms associated with the P0345 code is a rough or erratic idle when the vehicle is stationary or idling.
- Engine Misfires: A malfunctioning camshaft position sensor can cause intermittent or consistent engine misfires, resulting in uneven engine performance and potentially reduced power.
- Decreased Engine Performance: Vehicles experiencing the P0345 code may exhibit decreased engine performance, including sluggish acceleration and reduced overall power output.
- Engine Stalling: In some cases, the engine may stall or shut off unexpectedly, particularly during idle or low-speed driving, due to inaccurate camshaft position readings.
- Difficulty Starting: A malfunctioning camshaft position sensor can affect the engine’s ability to start smoothly, leading to extended cranking times or difficulty starting the engine altogether.
- Reduced Fuel Efficiency: Engine performance issues associated with the P0345 code can also lead to decreased fuel efficiency, as the engine may not operate optimally.
