OBD2P0883
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

TCM Power Input Signal High.

Severity

highCan drive, but transmission may not shift properly.

Summary

P0883 indicates that there is high voltage in the power input signal to the transmission control module (TCM). This can affect how the TCM operates and may cause issues with the transmission.

Symptoms

  • Check Engine light illuminated
  • Transmission enters limp mode, preventing shifting

Common Causes

  • Wiring issue or corrosion on the transmission control circuit
  • Pushed-out or bent pins in connector at PCM or TIPM modules
  • Bad alternator producing excessive voltage
  • PCM fault

Diagnosis

  1. Check the wiring diagram for your specific vehicle model.
  2. Test resistance between PCM and TIPM to ensure it reads 5.0 ohms.
  3. Inspect connectors for corrosion, bent pins, or moisture.
  4. Replace alternator if excessive voltage is detected.
  5. Consider replacing the PCM if other issues persist.

Fixes

  • Repair wiring and connectors as needed.
  • Replace faulty components such as alternator or PCM.
