Code P0710 Description
The P0710 diagnostic trouble code (DTC) indicates a malfunction within the Transmission Fluid Temperature Sensor 'A' circuit. This sensor is responsible for monitoring the temperature of the transmission fluid and sending the information to the vehicle's engine control module (ECM). The ECM uses this data to adjust various parameters such as shift points, torque converter lock-up, and engine performance to ensure optimal operation of the transmission system.
Common Causes of P0710
- Faulty Transmission Fluid Temperature Sensor: The sensor itself may be malfunctioning, leading to inaccurate temperature readings.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the sensor can cause circuit malfunction.
- Faulty Engine Control Module (ECM): A malfunctioning ECM may not be able to interpret the sensor data correctly, leading to the P0710 code.
- Low Transmission Fluid Levels: Inadequate fluid levels can affect the sensor's ability to accurately measure the temperature of the transmission fluid.
Symptoms of P0710
- Illuminated Check Engine Light: The most common symptom associated with the P0710 code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Harsh Shifting: The transmission may experience harsh or erratic shifting patterns due to incorrect temperature readings.
- Decreased Fuel Efficiency: Incorrect adjustments made by the ECM based on faulty temperature readings can lead to decreased fuel efficiency.
- Transmission Overheating: In severe cases, the transmission may overheat due to improper temperature management.
How to Fix P0710
- Diagnostic Scan: Begin by using a diagnostic scan tool to retrieve the specific DTC and verify the issue related to the Transmission Fluid Temperature Sensor 'A' circuit malfunction.
- Inspection: Inspect the sensor, wiring harness, and ECM for any visible damage or signs of wear that may be causing the malfunction.
- Sensor Replacement: If the sensor is faulty, replace it with a new one and ensure proper installation.
- Wiring Repair: Repair any damaged wiring or connections in the circuit to ensure a reliable connection between the sensor and the ECM.
- ECM Replacement: In rare cases where the ECM is faulty, it may need to be replaced or reprogrammed to resolve the issue.
Cost to Fix P0710
The cost of repairing a Transmission Fluid Temperature Sensor 'A' circuit malfunction can vary depending on the specific cause of the issue and the make and model of the vehicle. In general, the cost of parts for this repair can range from $50 to $200, while the labor cost can range from $100 to $300. This brings the total estimated cost to $150 to $500.

Discuss the causes and fixes for P0710 OBDII Code
-
What model and year is your vehicle? usually the problem is the sensor, but you could start by changing the transmission fluid.
-
There is a factory service bulletin with this information:
If you get a '00-03 3.2TL, '01-03 3.2CL, '01-02 MDX, or '02-03 RSX in for service with DTC P0710 (ATF temperature sensor) set, check for a faulty temperature sensor or a problem with the ATF temperature sensor circuit. This DTC is caused by an electrical problem and cannot be caused by a mechanical problem in the transmission.
The ATF temperature sensor is accessible without disassembling the transmission. To repair P0710 replace the faulty sensor. If the sensor is broken, carefully insert a self-tapping screw into the broken portion of the sensor. Be careful not to push on the broken portion of the sensor or it'll fall into the transmission, and that will require a transmission replacement.
