P0369
UniversalCamshaft Position Sensor B Circuit Intermittent (Bank 2)
Medium SeverityThe P0369 code indicates that the vehicle's engine control module (ECM) detects an intermittent signal from the Camshaft Position Sensor B on engine bank 2. This intermittent signal can lead to various engine performance problems, including rough idling, stalling, and reduced power.
⚠️ Before You Begin (Safety First)
Always ensure the vehicle is on a level surface and supported by jack stands if working underneath. Disconnect the battery before performing any electrical repairs to prevent accidental short circuits or injury. Allow the engine to cool down before handling any components.
Common Symptoms
- Check Engine Light illuminated
- Engine cranks but won't start
- Rough idling or stumbling engine
- Engine stalling unexpectedly
- Reduced engine power or poor acceleration
- Poor fuel economy
- Engine misfires
Common Causes
- Faulty or failing Camshaft Position Sensor B (Bank 2)
- Damaged or corroded wiring or connectors to the sensor
- Intermittent open or short in the sensor circuit
- Loose or contaminated sensor connection
- Issues with the reluctor ring (tone wheel) on the camshaft
- Rarely, a faulty Engine Control Module (ECM)

Diagnostic Steps
- Visually inspect the wiring and connector for the Camshaft Position Sensor B (Bank 2) for any signs of damage, corrosion, or loose connections.
- Ensure the sensor is properly seated and secured in its mounting location.
- If accessible, perform a resistance test on the Camshaft Position Sensor B according to your vehicle's service manual specifications.
- Check for any technical service bulletins (TSBs) related to P0369 for your specific make and model.
- Clear the code and test drive the vehicle to see if the code returns.
👨🔧 When to Call a Professional
If you have performed basic checks and the symptoms persist or the engine performance worsens significantly, it is best to consult a certified mechanic for a thorough diagnosis and repair.
Commonly Asked Questions
What does an intermittent camshaft position sensor signal mean?
An intermittent signal means the sensor is sending inconsistent or sporadic readings to the engine's computer, rather than a continuous, stable signal. This can disrupt engine timing and fuel delivery.
Can I drive my car with a P0369 code?
While you might be able to drive, it's not recommended for long periods. The intermittent signal can cause unpredictable engine stalling or loss of power, which can be dangerous. It's best to diagnose and repair it promptly.
How can I pinpoint if the sensor or wiring is at fault for P0369?
Start by checking the wiring and connector for visible damage. If they look good, a multimeter can be used to test the sensor's output signal while wiggling the wiring. A sudden change in readings indicates a wiring issue, while consistently bad readings point to the sensor.
What is 'Bank 2' and 'Sensor B' in the context of P0369?
'Bank 2' refers to the side of the engine that does not contain cylinder #1. 'Sensor B' typically refers to the exhaust camshaft position sensor on that bank. Consult your vehicle's service manual to confirm.
Is replacing the camshaft position sensor a difficult DIY task?
The difficulty varies significantly by vehicle model. On some vehicles, it's easily accessible and requires basic tools. On others, it may be located in a hard-to-reach area, requiring more extensive disassembly. It's generally considered a medium difficulty repair for most DIYers.
