Camshaft Position Sensor A Circuit High (Bank 2)
What it means
The engine computer has seen the signal voltage from camshaft position sensor A on bank 2 stay above its normal limit. This usually comes from an open signal or ground wire, or a signal wire shorted to a voltage source.

Symptoms4
- Check engine light on.
- Reduced power because variable valve timing (VVT) on bank 2 is disabled.
- Long cranking on some vehicles.
- Occasional slight roughness.
Possible causes5
- Open in the sensor signal or ground wire.
- Loose or corroded connector terminal.
- Signal wire shorted to a supply wire in the harness.
- Internal sensor failure.
- Faulty engine computer (rare).
How to diagnose5
- Watch the sensor signal voltage on a scan tool and compare it with the bank 1 sensor.
- Inspect the connector for loose or corroded terminals.
- Check continuity of the signal and ground wires between the sensor and the engine computer.
- Unplug the sensor and confirm there is no unexpected voltage on the signal wire.
- If the circuit is sound, replace the sensor, or swap it with the bank 1 sensor if identical to confirm.
How to fix5
- Repair loose connector terminals and clean the connector.
- Repair the broken wire or the short to voltage.
- Repair a corroded ground point.
- Replace the bank 2 cam sensor if it is proven faulty.
- Clear the codes and confirm a steady signal with no return of the code.
Repair cost
In Saudi riyals; the highlighted part is the expected range for this fault.
In the Saudi market: SAR 100–600 (≈ USD 27–160)
Our prices come from the Saudi market, converted at a fixed rate (SAR 3.75 per USD). Prices in your country may differ a lot, so we show the cost level.
The cost is low for a terminal or wire repair, and rises when the sensor is replaced or is hard to reach on bank 2.
Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions
How is this different from P0343?
It is the same type of electrical fault, but P0343 is for sensor A on bank 1 and this code is for sensor A on bank 2, so a different sensor and wiring are tested.
Can this code damage the engine?
Usually not directly, but it reduces performance and can cause long cranking, so repair it soon.
