P2352 indicates the powertrain control module has detected an electrical circuit malfunction in the pressure sensor specifically monitoring cylinder 10. This sensor measures in-cylinder combustion pressure to optimize timing and detect knock conditions. The code sets when voltage or resistance readings fall outside expected parameters for that circuit.
The piezoelectric or strain-gauge sensor mounted in cylinder 10 may develop internal resistance faults, signal drift, or complete failure due to thermal cycling and combustion exposure.
The circuit between the sensor and PCM may have opens, shorts-to-ground, shorts-to-voltage, or high resistance from chafing, heat damage, or rodent activity in the engine harness.
The sensor electrical connector may exhibit terminal spread, corrosion from moisture intrusion, or poor contact causing intermittent or static circuit failures.
Loss of the 5-volt reference supply or sensor ground to the cylinder 10 pressure sensor circuit will trigger this code and disable accurate pressure readings.
Rare internal driver or analog-to-digital converter failure within the control module affecting only the cylinder 10 pressure input channel; only plausible after all wiring and sensor tests pass.
It measures real-time combustion pressure inside the specific cylinder, allowing the PCM to detect knock, calculate optimal ignition timing, and monitor for mechanical faults like pre-ignition or valve issues.
No. Without valid pressure feedback, the PCM cannot detect destructive knock or misfires on cylinder 10, risking piston, ring, or connecting rod damage; limit driving to the minimum necessary to reach service.
Almost certainly not. Genuine PCM failure causing only a single-cylinder pressure circuit code is statistically rare; insist on verifying the sensor and every inch of wiring first, as unnecessary PCM replacement usually does not resolve P2352.
You can clear it to verify the fault is current, but if the underlying circuit or sensor issue remains, the code will reset immediately or after the next drive cycle, and continued operation risks engine damage.
