P2364Cylinder 11 Pressure Variation High
- 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
- 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.
