What P2361 means
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.

- Typical labor1 to 9 hours
- Clears after repairAfter a drive cycle
Symptoms of P2361
- Check engine light on
- Uneven running, especially at idle
- Possibly misfire code for cylinder 11 as well
Common causes of P2361
- PossibleInjector of cylinder 11 with reduced flow or clogged nozzle
- PossibleWorn piston rings or burnt valve lowering compression
- PossibleLeak at the glow plug seat
- Less likelyPressure sensor drifting low
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2361 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 3 | Area: ignition system or misfire. |
| 61 | The exact fault in that area. |
What to do next
- Note P2361 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2361
What does P2361 mean?
P2361 means "Cylinder 11 Pressure Too Low". P2361 says the combustion pressure of cylinder 11 is too low although the sensor works electrically. It is a generic code, so it means the same on every make.
Is it safe to drive with P2361?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2361 fail an emissions test?
Yes, it can. P2361 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2361 to fix?
Difficulty: hard. A typical repair takes 1 to 9 hours of work. This is a job for a workshop.
Will P2361 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
