P0368
Camshaft Position Sensor B Circuit High Bank 1
Ignition / engine timing
Generic OBD-II
High
What it means
P0368 means the bank 1 "B" camshaft position sensor is sending a higher-than-expected signal to the ECM. The computer uses cam position to time fuel and spark, so an unreliable signal here can cause rough running, stalling, hard starting, or an intermittent no-start. The fault is normally the sensor, its wiring, or the connector.
High
Can I keep driving? Risky — a cam-position fault can cause stalling, hard starting, or a no-start; keep driving to a minimum until it is fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Hard starting or intermittent no-start
- Stalling or rough running
- Reduced power and higher fuel consumption
Common causes
Most likely first
- Failed camshaft position sensor B (bank 1)Likely
- Signal wire shorted to voltage or open in the circuitCommon
- Loose or corroded connector at the sensorCommon
- Damaged reluctor/tone ring on the camshaftLess often
- ECM fault (rare — verify sensor and wiring first)Less often
How to diagnose & fix
Work through it in order
- Scan and read freeze-frame data to confirm the fault is the bank 1 cam sensor B circuit.
- Inspect the connector and harness for a short to voltage, oil contamination, or corrosion.
- Back-probe the sensor for supply, ground, and a clean signal while cranking.
- Check the sensor air gap and the reluctor ring for damage or debris.
- Replace cam position sensor B if it fails testing with good wiring. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0368?+
Not for long — the engine may stall or refuse to restart. Have it diagnosed before depending on the vehicle.
Can I just clear P0368?+
It comes back once the ECM re-tests the circuit, and it won't cure hard-starting. The wiring or sensor must be repaired.
