What does P0713 mean?

This code comes from the transmission control system. The fluid temperature sensor signal is open (reads very cold).

The signal is reading higher than the sensor can normally produce, which points at a wiring fault or a dead sensor.

Codes are a starting point. They tell you which test failed, not which part to replace. Check for other stored codes and fix those in a sensible order.

Symptoms

  • Check engine light
  • Harsh, late or erratic shifting
  • Transmission stuck in one gear (limp mode)
  • Flare between gears

Common causes

  • Open sensor ground wire
  • Signal wire shorted to the 5 V reference or to battery voltage
  • Water in the connector
  • Failed sensor

How to diagnose P0713

  1. Check the sensor ground first: an open ground drives the signal high.
  2. Unplug the sensor: if the signal still reads high, look for a short to voltage in the harness.
  3. If the wiring is good, replace the sensor.
  4. Check fluid level and condition using the correct procedure for your transmission.
  5. Read codes from the transmission module itself, not just the engine computer.

How to fix it

  • Correct the fluid level and service the fluid
  • Repair wiring
  • Replace the solenoid or valve body
  • Repair or replace the transmission if worn

Estimated repair cost

Likely repairs for P0713 run from about $150 to $5,500, depending on the cause.

RepairTypical range (parts + labor)
Diagnostic fee (scan + testing)$100 - $200
Transmission fluid and filter service$150 - $400
Transmission solenoid / solenoid pack$300 - $900
Transmission rebuild or reman unit$2,500 - $5,500

These are rough US estimates for an independent shop in 2026, based on typical parts prices and standard labor times. Dealers, big trucks, luxury brands and high-cost areas often run higher. They are not quotes. Use the repair cost estimator to adjust for your vehicle.

How serious is P0713?

High severity

Limp mode often locks the transmission in one gear. Drive gently and only as far as the shop.
