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.
Medium severity. Can I keep driving?If the car is running normally, drive in moderation to a repair shop. If it loses power or another warning appears, do not continue.
Cylinder 10 is numbered according to the manufacturer: check your engine's manual before working on it.
Symptoms
- Check engine light on
- No noticeable change in engine behaviour
Most likely causes
- Sensor offset drifted with age and heat
- Carbon on the heater rod hampers pressure transfer to the diaphragm
- Replacement glow plug with calibration for another engine
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
- It affects emissions.
What each character of P2353 means
- P: Powertrain: engine and transmission
- 2: Generic code: same on every make
- 3: Ignition and misfires
- 53: Specific fault in that system
Frequently asked questions
