Common Symptoms

  • Check Engine Light illuminated intermittently
  • Occasional harsh shifting
  • Temperature reading jumps erratically on scan tool
  • Intermittent limp mode

Probable Causes (Ranked by Likelihood)

  • Loose TFT sensor connector Very High
  • Intermittent break in TFT sensor wiring High
  • Failing TFT sensor with intermittent internal fault Moderate
  • Transmission fluid contamination on connector pins Moderate

Step-by-Step Diagnostic Procedure

  1. Wiggle the TFT sensor connector while monitoring temperature readings for dropouts

  2. Inspect connector for transmission fluid contamination or corrosion

  3. Check wiring at stress points near the transmission for broken strands

  4. Clean connector and apply dielectric grease, then monitor for recurrence

  5. Replace the TFT sensor if intermittent readings persist

Frequently Asked Questions

Can I drive with code P0714?

Drive short distances. Intermittent temperature reading faults can cause unpredictable shift behavior when the reading drops out.

Can transmission fluid leaking onto the connector cause P0714?

Yes. Transmission fluid leaking from the sensor or a gasket can contaminate the connector pins, creating an intermittent electrical connection.

How do I fix an intermittent TFT sensor?

Start by cleaning the connector with electrical cleaner and applying dielectric grease. If the problem returns, replace the sensor.
