UniversalCamshaft Position Sensor B Circuit Intermittent (Bank 2)
The engine computer has detected an intermittent signal or circuit condition in the Bank 2 Camshaft Position Sensor B circuit. The camshaft position signal helps the computer track camshaft position and coordinate engine operation. A signal that cuts in and out may affect starting or running, but this code alone does not prove the sensor needs replacement.
⚠️ Before You Begin (Safety First)
If the engine stalls, runs very poorly, or becomes difficult to control, pull over somewhere safe and arrange assistance. If the warning light is on but the vehicle runs normally, get the fault diagnosed promptly and watch for worsening symptoms.
Common Symptoms
- The check-engine light may be on, even if the vehicle seems to run normally.
- Intermittent or inaccurate camshaft position information may cause rough running or hesitation.
- Starting may become difficult if the engine computer cannot reliably use the camshaft position signal.
- The engine may stall if the signal drops out while running.
- There may be no noticeable symptoms when the intermittent condition is brief or does not affect engine operation.
Common Causes
- A loose, damaged, or corroded connection in the Bank 2 Sensor B circuit may interrupt the signal.
- Wiring damage or an intermittent electrical connection may cause the circuit condition.
- The camshaft position sensor may intermittently fail, but the code alone does not confirm this.
- A damaged or obstructed signal target, or a mechanical camshaft timing problem, may contribute to an irregular signal.
Diagnostic Steps
- Record the stored codes and any available freeze-frame information before clearing anything; this can help show when the intermittent condition occurred.
- With the engine off and cool, visually inspect accessible wiring and the Bank 2 Sensor B connector for looseness, visible damage, corrosion, or contact with hot or moving parts.
- Check whether the code returns after noting the conditions, but do not continue driving if the engine stalls or runs severely poorly.
- Use service information for the exact vehicle before attempting electrical tests or sensor removal; avoid probing terminals or replacing parts based only on the code.
When to Call a Professional
Check stored and pending codes and freeze-frame information, then inspect the Bank 2 Sensor B connector and wiring for damage, looseness, corrosion, or routing problems. Use vehicle-specific service information to evaluate the circuit and sensor signal; if those checks do not explain the intermittent fault, investigate the signal target and mechanical camshaft timing as appropriate.

Commonly Asked Questions
Does P0369 mean the camshaft position sensor must be replaced?
No. It identifies an intermittent condition in the Bank 2 Camshaft Position Sensor B circuit. Wiring, connections, the signal target, or mechanical timing may also need investigation.
What does “intermittent” mean in this code?
The monitored circuit or signal was not consistently present or usable. The condition may come and go, so symptoms and code status can vary.
Can I drive with P0369?
If the vehicle runs normally, arrange diagnosis promptly and monitor it. If it stalls, runs very poorly, or becomes difficult to control, stop in a safe place and seek assistance.
Why might there be no noticeable symptoms?
A brief signal interruption may not noticeably affect engine operation, even though the computer detected the circuit condition.
Is Bank 2 Sensor B location the same on every vehicle?
No. Exact sensor identification and location depend on the vehicle's model, year, and engine. Check vehicle-specific service information before inspecting or replacing parts.
