P2353Cylinder 10 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
- P2353 means the cylinder 10 pressure sensor delivers a signal that is electrically within limits but not believable for the current operating point – the reading is skewed, not cut off. CARB expects input sensors to be checked for such rationality faults, not just for open or shorted circuits. How an ECM can do this is visible in Saab's 9-5 diesel: it locates top dead centre from the pressure peak on overrun, corrects the offset of the crank trigger wheel and keeps the result in EEPROM. A drifted sensor, a heater rod that no longer passes pressure on to the measuring diaphragm, or a replacement plug whose calibration does not suit the engine would all fail such a test. No manufacturer documents P2353 for cylinder 10. The engine runs normally; only pressure-based control of this cylinder is lost.
- What you may notice
- Check engine light on
- No noticeable change in engine behaviour
- Likely causes
- LikelySensor offset drifted with age and heat
- PossibleCarbon on the heater rod hampers pressure transfer to the diaphragm
- RareReplacement glow plug with calibration for another engine
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
