P0710: Transmission Fluid Temperature Sensor Circuit Malfunction

ModeratePowertrainDIY: Advanced

Can you still drive? Drive cautiously and avoid towing or heavy loads. Without proper temperature monitoring, the transmission could overheat without warning. Get it repaired promptly.

What Does P0710 Mean?

Code P0710 indicates a malfunction in the transmission fluid temperature sensor circuit. The TCM uses fluid temperature data to adjust shift timing, line pressure, and torque converter lockup strategies. Without accurate temperature data, the transmission may not perform optimally and could be at risk of overheating damage.

Need to read your codes?

An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

Common Causes

  • Faulty transmission fluid temperature sensor
  • Damaged wiring or connector to the sensor
  • Contaminated or degraded transmission fluid
  • Internal transmission harness failure
  • Corroded sensor connector pins

Symptoms

  • Check engine light on
  • Harsh or delayed transmission shifts
  • Transmission overheating
  • Transmission stuck in limp mode
  • Poor fuel economy due to torque converter not locking up

Diagnostic Steps

  1. 1Read transmission fluid temperature with a scan tool and compare to engine coolant temperature when cold
  2. 2Both temperatures should be similar when the vehicle has been sitting overnight
  3. 3Check sensor connector and wiring for damage
  4. 4Measure sensor resistance and compare to temperature-resistance chart
  5. 5Inspect transmission fluid condition for contamination
  6. 6Check internal transmission harness if sensor is internally mounted

Frequently Asked Questions

Why does transmission fluid temperature matter?

Transmission fluid temperature affects viscosity and lubricating ability. The TCM adjusts shift pressure and timing based on temperature to protect the transmission and provide smooth shifts.

Where is the transmission temperature sensor located?

It is typically located inside the transmission in the valve body area or in the transmission pan. Some vehicles have it externally on the transmission case or in a cooler line.
