Mazda vehicles have advanced onboard computer systems that monitor engine performance and alert drivers to potential issues. One of the codes that may be displayed is P0710, which stands for Transmission Fluid Temperature Sensor Circuit Malfunction. This code is triggered when the Powertrain Control Module (PCM) detects that the transmission fluid temperature sensor signal is either less than 0.10v or more than 4.90v. If this condition is met for 100 seconds, the P0710 code is displayed. In order to fix this issue, it is important to understand the underlying causes, which can include an open or shorted TFT sensor signal circuit, an open TFT sensor ground circuit, a shorted TFT sensor signal circuit, a damaged or failed TFT sensor, or a failed PCM.

Causes and Solutions for Mazda Code P0710
| Cause | Solution |
|---|---|
| TFT sensor signal circuit is open or shorted to ground | Replace the TFT sensor signal circuit |
| TFT sensor ground circuit is available between the sensor and PCM | Check wiring and connections. Repair or replace the TFT sensor ground circuit as necessary. |
| TFT sensor signal circuit shorted to VREF or system power | Check wiring and connections. Repair or replace the TFT sensor signal circuit as necessary. |
| TFT sensor is damaged, or has it failed | Replace the TFT sensor |
| PCM has failed | Replace the PCM |
Open or Short Circuit in the TFT Sensor Signal Circuit
The first step to resolving a Mazda Code P0710 is to check the TFT sensor signal circuit for an open or shorted condition. This may be caused by a wiring fault or a failed component, such as a connector, fuse, or relay. If a wiring fault is found, it should be repaired or replaced as necessary.

Open TFT Sensor Ground Circuit
If the TFT sensor ground circuit is open between the sensor and the PCM, this will cause the P0710 code to be displayed. It is essential to check the wiring and connections to ensure they are in good condition. If any wiring faults are found, they should be repaired or replaced as necessary.

Shorted TFT Sensor Signal Circuit
If the TFT sensor signal circuit is shorted to VREF or system power, the P0710 code will be displayed. Again, checking the wiring and connections is essential to ensure they are in good condition. If any wiring faults are found, they should be repaired or replaced as necessary.
Damaged or Failed TFT Sensor
A damaged or failed TFT sensor can also cause the P0710 code to be displayed. In this case, the sensor should be replaced.
Failed PCM
Finally, a failed PCM can also cause the P0710 code to be displayed. If the PCM has failed, it should be replaced.
Conclusion
Mazda Code P0710 indicates that the transmission fluid temperature sensor signal is either too low or too high. This code has several potential causes, ranging from wiring faults to damaged or failed components. To fix this issue, it is essential to understand the underlying causes and take the necessary steps to repair or replace any damaged parts. To prevent the Mazda Code P0710 from occurring again, it is essential to ensure that all components are in good condition and that all wiring and connections are secure.
