P1215 — Pedal Position Sensor C Circuit Low Input

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Generic

About P1215

P1215 is a manufacturer-specific powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P1215 is stored, the module has detected a signal or supply voltage lower than the expected operating range; and a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1215 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

This code relates to the accelerator pedal position sensor, specifically the C signal circuit, within the electronic throttle control system. The accelerator pedal module contains multiple redundant position sensors, and sensor C is one of the signals the module uses to confirm pedal demand and cross check the other sensors for safety. DTC P1215 is set when the module detects that the pedal position sensor C signal voltage is below the normal operating range, a circuit low input condition. This is commonly caused by a short to ground on the signal wire, an open reference feeding the sensor, or...
