Symptoms of P0367
- Rough idle, shaking, or a stumble under acceleration.
- A flashing check-engine light during an active misfire.
- Power loss and higher fuel consumption.
Common causes of P0367
- Worn spark plugs, ignition coils, or plug wires.
- Fuel-delivery problems — injectors, pressure, or a lean/rich mixture.
- Vacuum leaks, low compression, or a mechanical fault in that cylinder.
Useful checks before replacing parts
- Check sensor supply voltage, ground integrity, signal voltage, cam sensor waveform, connector condition, and freeze-frame data.
- Inspect for short-to-ground faults, open supply circuits, oil-contaminated connectors, damaged wiring, poor terminal fit, and target wheel damage.
- Compare voltage at the sensor and PCM connector to identify whether the low input is caused by the sensor, harness, or controller input.
