What P2352 means
P2352 is the catch-all code for the electrical circuit of the cylinder 10 combustion pressure sensor, meant for engine computers that make no distinction between low and high. A tenth cylinder exists only on V10 and V12 engines. Under the bank-by-bank numbering of Ford and Audi it is the rearmost cylinder of the second bank; Chrysler counts along the crankshaft, which makes it the last one, at the back, on the even-numbered bank. Publicly, no maker lists this code: the known pressure-sensing glow plug systems sit on four-cylinder diesels, such as VW's US 2.0 TDI with its own codes P13CE to P13E3. CARB wants circuit faults of input sensors watched continuously, sampled at least twice per second. Suspects are the connector, the harness and the sensor itself; meanwhile the ECM lacks combustion feedback for this cylinder.
P2352 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 P2352
- Check engine light on
- Engine usually runs as before
- Combustion noise may become slightly harder
Common causes of P2352
- Most likelyGlow plug/sensor connector of cylinder 10 not fully latched or corroded
- PossibleHarness branch to the rear cylinder of the bank chafed or heat-damaged
- PossibleElectronics in the pressure-sensing glow plug failed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2352 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. |
| 52 | The exact fault in that area. |
What to do next
- Note P2352 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 P2352
What does P2352 mean?
P2352 means "Cylinder 10 Pressure Sensor Circuit". P2352 is the catch-all code for the electrical circuit of the cylinder 10 combustion pressure sensor, meant for engine computers that make no distinction between low and high. It is a generic code, so it means the same on every make.
Is it safe to drive with P2352?
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 P2352 fail an emissions test?
Yes, it can. P2352 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 P2352 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3.5 hours of work. This is a job for a workshop.
Will P2352 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.
