Camshaft Position Sensor A Circuit (Bank 2)

What is P0345?

P0345 is a high-severity powertrain code indicating a circuit problem with the camshaft position sensor on engine bank 2, which can disrupt engine timing and fuel delivery. Based on 141 reports, this issue is most common in Ford vehicles, particularly the Mustang and F-150. The average repair cost is $2043, but it can range from $0 for a DIY fix to over $4000 for major repairs.

Common Causes

• ●A faulty camshaft position sensor or its circuit, which is the primary electrical issue triggering the code.
• ●Oil leaks or contamination affecting the sensor, as seen in Ford F-150 reports where the valve cover or PCV system was involved.
• ●Wiring harness damage or connector issues leading to poor electrical signals from the sensor.

Symptoms You May Notice

• ●The check engine light is illuminated, which is the primary indicator that triggered the diagnostic scan.
• ●Engine performance issues like rough idling, hesitation, or reduced power, though specific driving symptoms are less frequently detailed in owner reports.
• ●Difficulty starting the vehicle or intermittent stalling, as the incorrect camshaft signal disrupts ignition timing.

How to Fix It

• ●Replacing the camshaft position sensor itself, which is a common repair but cost varies widely by vehicle ($25-$7500, moderate difficulty).
• ●Repairing or replacing the valve cover or PCV system if an oil leak is contaminating the sensor, as successfully fixed in multiple Ford F-150 cases for around $180 (moderate difficulty).
• ●Diagnosing and repairing wiring or connector issues in the sensor circuit, which may involve checking for breaks or corrosion (cost varies, high difficulty for electrical work).
