What P2353 means
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 deceleration, 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.
P2353 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 3.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2353
- Check engine light on
- No noticeable change in engine behaviour
Common causes of P2353
- Most likelySensor offset drifted with age and heat
- PossibleCarbon on the heater rod hampers pressure transfer to the diaphragm
- Less likelyReplacement glow plug with calibration for another engine
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2353 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. |
| 53 | The exact fault in that area. |
What to do next
- Note P2353 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 P2353
What does P2353 mean?
P2353 means "Cylinder 10 Pressure Sensor Circuit Range/Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2353?
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 P2353 fail an emissions test?
Yes, it can. P2353 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 P2353 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3.5 hours of work. This is a job for a workshop.
Will P2353 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.
