About P2133

P2133 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P2133 is stored, the module has detected a signal or supply voltage higher 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.

Because P2133 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Engine Control Module (ECM) monitors multiple throttle and accelerator pedal position sensor circuits to ensure accurate and redundant driver input detection. DTC P2133 is set when the ECM detects that the throttle or pedal position sensor F signal voltage is higher than the specified maximum for a calibrated period, or remains high when a lower or changing voltage is expected. This indicates a high voltage fault in the sensor signal circuit, and the ECM responds by entering a fail safe operating mode that limits engine power. The driver may notice reduced throttle response, hesitation, or...
