P0710 Transmission Fluid Temperature Sensor Circuit Malfunction

Code: P0710

Description: Transmission Fluid Temperature Sensor Circuit Malfunction

Definition: This diagnostic trouble code (DTC) indicates a malfunction in the transmission fluid temperature sensor circuit. It means that the powertrain control module (PCM) has detected an abnormal signal from the transmission fluid temperature sensor, which could be due to wiring issues, a faulty sensor, or other related problems.

P0710 – Transmission Fluid Temperature Sensor Circuit Malfunction

Typical Severity: Moderate

Common Causes

P0710 – Transmission Fluid Temperature Sensor Circuit Malfunction

Common Causes:

• Faulty transmission fluid temperature sensor
• Open or short circuit in the wiring harness connected to the sensor
• Corroded or poor electrical connections related to the sensor
• Low transmission fluid level or contaminated fluid
• Faulty engine control module (ECM) or transmission control module (TCM)

 

Common Misdiagnosis

OBD2 Code: P0710

Description: Transmission Fluid Temperature Sensor Circuit Malfunction

Common Misdiagnosis: Replacing the transmission fluid temperature sensor without checking for wiring issues or poor electrical connections.

 

Common Diagnostic Steps

OBD2 Code: P0710

Description: Transmission Fluid Temperature Sensor Circuit Malfunction

• Check the transmission fluid level and condition. Ensure it is at the correct level and not contaminated.
• Inspect the wiring and connectors for any signs of damage, corrosion, or disconnection in the transmission fluid temperature sensor circuit.
• Test the transmission fluid temperature sensor using a multimeter to ensure it is functioning correctly. Compare readings with manufacturer specifications.
• Examine the Powertrain Control Module (PCM) for any software updates or faults that may affect sensor operation.
• If necessary, replace the faulty transmission fluid temperature sensor with a new one.
• Clear the OBD2 codes from the PCM and perform a test drive to verify if the issue has been resolved.
