P2361Cylinder 11 Pressure Too Low
- 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
- P2361 says the combustion pressure of cylinder 11 is too low although the sensor works electrically. No manufacturer documents this code, since no twelve-cylinder engine with combustion pressure sensing is publicly described. What the code judges is the cylinder itself: if its peak stays clearly below that of comparable cylinders or below the expected value, combustion or compression is lacking. Candidates are an injector with reduced flow or a clogged nozzle, worn rings or a burnt valve that lowers compression, a leak at the glow plug seat, or a sensor drifting low. A compression or leak-down test separates mechanical faults from injection faults. The engine runs unevenly, particularly at idle, and the cylinder 11 misfire code P0311 may be stored as well.

- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
