What are the probable causes of DTC P0710?

The best solution you'll get from books at www.reliable-store.com

These are books containing info on repair, service, troubleshooting, parts info, assembling dissemble, removal, error/fault codes, wiring diagrams and everything on any vehicle- cars, atv, trucks. forklifts, boats, excavators etc.

You may need to add transmission fluid. Also, check the transmission fluid sensor to see if it's fully plugged in or if the wires are binding. It all else fails, replace the fluid sensor.

HERE IS THE ANSWER.
P0725 - Nissan Type Powertrain - Transmission - ISO/SAE Controlled Description Engine speed (RPM) - incorrect voltage signal ECM to TCM
Cause Wiring, RPM sensor, TCM, ECM
P0720 - Nissan Type Powertrain - Transmission - ISO/SAE Controlled Description AT - vehicle speed sensor (VSS)
Cause Wiring, VSS, TCM
P0710 - Nissan Type Powertrain - Transmission - ISO/SAE Controlled Description Transmission fluid temperature sensor - excessively high or low voltage
Cause Wiring, temperature sensor, TCM, ECM
P0826 - Generic Type Powertrain - Transmission - ISO/SAE Controlled Description Up and Down Shift Switch Circuit

the dtcs of your car are so many, my best suggest is go to garage for repair. or if you would like to repair by yourself, you need to buy a diagnostic tool such as multidiag j2534

Here's a link to a recall,dealer may give you a free transmission. http://www.hondaproblems.com/recalls/Odyssey/2002

DTC P2089 - A Camshaft Pos Actuator Ctrl Circ Hi Bank1
DTC P2133 - Throttle/Pedal Position Sensor/Switch 'F' Circuit High
DTC P2510 - ECM/PCM Power Relay Sense Circ Range/Perf

Sound like a problem with the Camshaft sensor.

Buy a Bentley's or join a VW forum, surely they will have forums for DTC code description.

clear the errors and run car, then scan agian, and see what code comes back up.
