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.

Likely causes

Glow plug/sensor connector of cylinder 10 not fully latched or corroded

Harness branch to the rear cylinder of the bank chafed or heat-damaged

Electronics in the pressure-sensing glow plug failed

Symptoms

Check engine light on
Engine usually runs as before
Combustion noise may become slightly harder
