OBD-II DTC P1260 – Pedal Correlation PDS2 and LPDS Low

DTC P1260 meaning

DTC P1260 refers to a diagnostic trouble code that indicates a problem with the pedal correlation between the Powertrain Control Module (PCM) and the throttle position sensor. This code is often associated with issues in the Low Pedal Position Sensor (LPDS) and the Pedal Position Sensor 2 (PDS2). The PCM uses these sensors to determine the position of the accelerator pedal and adjust engine performance accordingly.

DTC P1260 symptoms

Common symptoms associated with DTC P1260 may include:

  • Illuminated check engine light
  • Reduced engine power or performance
  • Unresponsive throttle
  • Erratic engine behavior
  • Difficulty in accelerating

DTC P1260 causes

Several factors can lead to the triggering of DTC P1260, including:

  • Faulty Pedal Position Sensor 2 (PDS2)
  • Faulty Low Pedal Position Sensor (LPDS)
  • Wiring issues or poor connections in the sensor circuit
  • Faulty Powertrain Control Module (PCM)
  • Mechanical issues with the throttle body

DTC P1260 seriousness

DTC P1260 is considered a serious issue as it can lead to reduced engine performance and may affect vehicle drivability. If left unaddressed, it can result in further damage to the engine or related components. It is advisable to diagnose and repair the issue promptly to ensure safe vehicle operation.

How to fix DTC P1260 step-by-step instructions

To fix DTC P1260, follow these step-by-step instructions:

  1. Clear the DTC using an OBD-II scanner.
  2. Inspect and repair any damaged wiring or connectors related to the PDS2 and LPDS.
  3. If necessary, replace the faulty Pedal Position Sensor 2 (PDS2) or Low Pedal Position Sensor (LPDS).
  4. Ensure that the throttle body is functioning correctly and is free of obstructions.
  5. Reconnect all connectors and wiring securely.
  6. Start the vehicle and monitor for any reoccurrence of the DTC.

How to erase DTC P1260
