P1135 — Pedal Position Sensor A Circuit Intermittent

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

About P1135

P1135 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 P1135 is stored, the module has detected 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.

P1135 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 sets when the powertrain control module (PCM) detects an intermittent or erratic signal from the accelerator pedal position sensor (APPS) circuit 'A'. The APPS provides input to the PCM for throttle control in electronic throttle control (ETC) systems. An unstable signal can lead to poor throttle response or reduced engine power.
