P0714 — Transmission Fluid Temperature Sensor Circuit Intermittent

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P0714

P0714 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P0714 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0714 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

This fault code is triggered when the Transmission Control Module (TCM) detects intermittent signals from the transmission fluid temperature sensor circuit. The transmission fluid temperature sensor is critical for monitoring the temperature of the transmission fluid, ensuring the transmission operates within safe thermal limits. An intermittent fault in this sensor circuit suggests sporadic disruptions in the signal flow, which can be due to loose connections, intermittent sensor failure, or wiring issues. Such intermittent faults can lead to inconsistent temperature readings, potentially cau...
