UniversalCamshaft Position Sensor B Circuit (Bank 2)
The engine computer has detected a problem in the circuit for camshaft position sensor B on Bank 2. This sensor provides information used to track camshaft position and coordinate engine operation. The code identifies a detected circuit condition, but does not by itself prove the sensor is faulty.
⚠️ Before You Begin (Safety First)
If the engine stalls, runs very poorly, or is difficult to keep running, stop in a safe place and arrange diagnosis rather than continuing to drive. If the warning light is on but the engine runs normally, drive cautiously and have the fault checked soon.
Common Symptoms
- The check-engine light may be on, with no noticeable change in how the vehicle runs.
- The engine may start difficultly or crank without starting if the computer cannot use the camshaft position signal reliably.
- The engine may run roughly, hesitate, or lose power if the signal problem disrupts engine control.
- The engine may stall if the signal becomes unreliable while driving.
Common Causes
- Camshaft position sensor B on Bank 2 may have an internal fault.
- The sensor connector may be loose, damaged, or contaminated.
- Wiring in the sensor circuit may be damaged, corroded, or making an intermittent connection.
- A circuit power or ground problem may prevent the sensor signal from being read correctly.
- A problem affecting the camshaft signal or its mechanical reference may require further investigation.
Diagnostic Steps
- Note whether the engine is running normally and whether the check-engine light is steady or flashing; stop driving if the engine stalls or runs severely poorly.
- With the engine off and cool, visually inspect accessible wiring and the sensor connector for looseness, damage, corrosion, or contamination. Do not pull on wires or disconnect components while the engine is running.
- Check for other stored diagnostic codes with a scan tool and record them before clearing anything, since related codes can help guide diagnosis.
- If the code returns or the cause is not obvious, use vehicle-specific service information or have a technician test the circuit; avoid replacing the sensor based on the code alone.
When to Call a Professional
Confirm the code and check for related codes. Inspect the sensor connector and harness, then use vehicle-specific wiring information and scan data to assess the sensor signal and its circuit. Further testing may be needed to distinguish a sensor problem from wiring, connector, power or ground issues, or a mechanical camshaft signal problem.

Commonly Asked Questions
Does P0365 prove that the camshaft position sensor needs replacement?
No. It identifies a detected problem in the camshaft position sensor B circuit on Bank 2. The sensor, connector, wiring, power or ground, and signal source may need to be checked.
Can I drive with P0365?
If the engine runs normally, cautious driving to arrange diagnosis may be possible. If it stalls, runs very poorly, or is difficult to keep running, stop safely and seek assistance.
What does sensor B, Bank 2 mean?
It distinguishes the monitored camshaft position sensor circuit from other sensor circuits and identifies the engine bank involved. The exact component location depends on the vehicle's engine.
Why might the vehicle have no symptoms?
The fault may be intermittent or the engine computer may still receive enough information for normal operation. The warning light can appear even when the change in engine behavior is not noticeable.
