Camshaft Position Sensor B Circuit Intermittent (Bank 2)
What it means
The engine computer has seen the signal from camshaft position sensor B on bank 2 drop out briefly and then return. This is usually caused by an unstable connection affected by vibration or heat from the nearby exhaust manifold, or a sensor that fails when hot.
Symptoms4
- Check engine light that comes and goes.
- Momentary jerk or stumble while driving.
- Intermittent loss of power.
- Rare stalling in some cases.
Possible causes6
- Loose connector or a terminal with poor grip.
- Cracked wire that opens with vibration or is affected by exhaust manifold heat.
- Sensor that fails when hot and then recovers.
- Oil or moisture inside the connector.
- Metal debris on the sensor tip.
- Weak ground.
How to diagnose5
- Review the freeze frame data to see engine temperature and speed at the time of the fault.
- Watch the signal while gently moving the wiring and connector with the engine running.
- Test connector terminal grip and look for oil, corrosion or heat marks on the harness.
- Drive to full operating temperature to see whether the fault is heat-related.
- Swap the sensor with bank 1 sensor B if identical; if the fault moves to P0369, the sensor is faulty.
How to fix5
- Clean the connector and repair loose terminals or replace the connector.
- Repair cracked wiring and secure it away from heat and vibration.
- Clean the sensor tip and fix any oil leak reaching it.
- Replace the sensor if it is proven to fail when hot.
- Clear the codes and road test under the same conditions that set the code.
Repair cost
In Saudi riyals; the highlighted part is the expected range for this fault.
The fix is often in the connector or wiring at low cost, but intermittent faults can take longer to diagnose, and the cost rises when the sensor is replaced.
Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions
Why does the fault appear only after long drives?
Heat expands terminals and wires and affects the sensor, so contact is lost once the engine is hot. This points to a heat-sensitive sensor or a wire near the exhaust manifold.
Can I drive with this code?
Usually yes with care, but momentary jerks or stalling can happen, so repair it before any long trip.

What was wrong? (optional)
This guide is for information only and does not replace an inspection by a qualified technician. If the fault involves brakes, steering, engine temperature, electrics or refrigerant, do not attempt the repair yourself.
