P2360Cylinder 11 Pressure Sensor Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2360 records a cylinder 11 combustion pressure signal that is unsteady – brief dropouts or spikes that do not last long enough for a low or high code. Since only twelve-cylinder engines have cylinder 11, and none is documented with pressure sensors, the code has no public manufacturer description. Saab's 9-5 diesel shows how quickly such a monitor acts: the erratic code for cylinder 1, P0399, is a Type B code that needs only a 0.2 s excursion beyond the permitted band with the engine turning. Contact problems dominate – a connector not fully latched, fretting corrosion on the terminals, a harness touching hot parts. Electronics in the plug head that only drop out once the engine is warm are another candidate. The fault often vanishes and returns days later.
