P2367Cylinder 12 Pressure Sensor Circuit Range/Performance
- 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
- With P2367 the cylinder 12 pressure signal is electrically within its limits but makes no sense for the operating point. A natural yardstick is the motored cycle: on overrun nothing burns, so the curve has to peak at top dead centre. Saab's 9-5 diesel uses exactly this peak position to locate true TDC and keeps in EEPROM how far the crank trigger wheel sits off its nominal angle – which shows how closely the ECM follows each sensor. A sensor whose peak shifts, whose zero has drifted or whose seat lets gas escape would fail such a check. No manufacturer documents P2367, because no twelve-cylinder engine with this sensor is public; the cylinder-1 equivalent is P0396. In most cases only the warning lamp is noticed.
- What you may notice
- Check engine light on
- Implausible peak pressure value for cylinder 12 compared with the others
- Likely causes
- LikelySensor zero point or gain drifted
- PossibleCombustion gas escaping at the glow plug seat
- RareGlow plug of a different calibration fitted
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
