Transmission Fluid Temperature Sensor Circuit High
The P0713 code means the vehicle's onboard diagnostic system has detected: Transmission Fluid Temperature Sensor Circuit High. This is a moderate severity code.
- Keep driving?
- Short distances only
- DIY difficulty
- moderate
- Estimated cost
- $80 - $300 (parts and labor)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.
Basic scanners only read engine codes. This reads transmission, ABS, and airbag too.

Common Symptoms
- Check Engine Light illuminated
- TCM assumes fluid is very cold
- Delayed or no upshift to higher gears
- Increased fuel consumption
Probable Causes (Ranked by Likelihood)
- Open TFT sensor (internal open circuit) Very High
- Open signal or ground wire in TFT circuit High
- Disconnected or corroded TFT sensor connector Moderate
- TCM input circuit fault Low
Frequently Asked Questions
Can I drive with code P0713?
Drive short distances. The TCM thinks the fluid is cold and will delay upshifts, hold lower gears longer, and increase line pressure, causing harsh shifts and higher RPMs.
Why does high circuit mean cold temperature reading?
The TFT sensor resistance increases as temperature drops. An open circuit reads as infinite resistance, which the TCM interprets as extremely cold fluid.
Can a disconnected connector cause P0713?
Yes. A simply disconnected or loose connector creates an open circuit that triggers P0713. Always check the connector first before replacing the sensor.
Mechanics Guide Step-by-step diagnosis
Step-by-Step Diagnostic Procedure
-
Check TFT reading on a scan tool -- abnormally low temperature when warm indicates high circuit
-
Measure sensor resistance -- OL (infinite) reading confirms open sensor
-
Inspect the TFT sensor connector for disconnection or corrosion
-
Check signal and ground wires for continuity to the TCM
-
Replace the TFT sensor if open internally
