Camshaft Position Sensor B Circuit High Bank 1
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.
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.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

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.
