Code details

Generic OBD-II · P0

System: Ignition / Misfire
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace the sensor until a high signal has been checked against ground integrity and short-to-voltage faults.

Symptoms of P0368

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 P0368

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

Review cam sensor B Bank 1 signal voltage, reference voltage, ground path, freeze-frame RPM, and other high-input sensor codes.
Inspect for open grounds, short-to-voltage faults, connector corrosion, harness insulation damage, sensor contamination, and target wheel problems.
Scope the cam signal during cranking and running to verify whether the signal toggles normally or remains biased high.
