What P2364 means
P2364 is stored when the pressure signal of cylinder 11 varies too strongly, from cycle to cycle or within one cycle. No maker publishes this code. Saab's 9-5 diesel has the analogous P039D for cylinder 1, a Type B signal fault reacting to 0.2 s outside its window. Excessive variation can stem from interference on the signal line, a ground connection whose resistance keeps changing, or moisture in the connector, but also from a cylinder whose combustion really scatters – an injector with an unstable spray pattern, or poor fuel. A variation limit is one way to meet CARB's demand for plausibility tests of input sensors. The MIL is usually the only symptom; P2363 covers the opposite, flat signal, and P2360 the short dropouts.
P2364 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor1 to 3.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2364
- Check engine light on
- No noticeable effect on driving
Common causes of P2364
- PossibleInterference coupling into the signal line
- PossibleGround connection with changing contact resistance
- Less likelyMoisture in the glow plug connector
- Less likelyInjector with unstable spray pattern
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2364 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. |
| 64 | The exact fault in that area. |
What to do next
- Note P2364 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 P2364
What does P2364 mean?
P2364 means "Cylinder 11 Pressure Variation High". P2364 is stored when the pressure signal of cylinder 11 varies too strongly, from cycle to cycle or within one cycle. It is a generic code, so it means the same on every make.
Is it safe to drive with P2364?
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 P2364 fail an emissions test?
Yes, it can. P2364 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 P2364 to fix?
Difficulty: medium. A typical repair takes 1 to 3.5 hours of work. This is a job for a workshop.
Will P2364 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.
