2006 Kia Sportage Question: What is involved in dealing with a P0711 code and its repair?

 

Question

Check engine light came on, took to dealer, they said they had the P0711 code, A/T temperature sensor, and it needed replacing(there was a bulletin out for this part). They estimated the cost at around $700. They reset the check engine light, so it is off. If I take it to another shop, can they check for the code and confirm it after the dealer reset it? The light came on after the car was parked all day, and I do not see any change in how the vehicle is running. Any ideas or suggestions on how to proceed would be greatly appreciated. Thank you!

    P0711 A/T Fluid Temperature Sensor Performance - With Automatic TransmissionPossible Causes Setting Conditions
    •ATF sensor connector is damaged (check pins for damage, and for moisture)
    •ATF signal circuit has a high resistance condition
    •ATF return circuit has a high resistance condition
    •ATF has failed
    Engine running; throttle opening over 12.5%, vehicle speed more than 6.2 mph, and the PCM detected the ATF signal did not match the corresponding threshold voltage. The Automatic Transaxle Fluid (ATF) temperature sensor is located in the valve body. It contains a thermistor whose resistance changes according to the temperature changes. The TCM supplies a 5-volt reference voltage to the sensor. The sensor signal changes when the ATF temperature varies. The ATF temperature signal provides key data that the TCM uses to control of the TCC and other solenoids.

    This code sets in 2 Trip(s).
    This code will turn on the MIL (Malfunction Indicator Lamp)

    I appreciate your response, but in layman's terms, what do I need to do? Before I spend the money. How do I verify which issue it is? Dealer said it failed, was reading 0 degrees. I am not a car person, but I need to know that I am
    not being taken advantage of. Performance out of range, verified failure. That is what the paperwork stated, nothing specific asyou stated aboveThank you.

    I hate it when people re set a code without repairing it. it does nothing but erase critical information for the person who repairs it.

    I think you need a trans shop and give them as much info as you can along with the code number. let them do a proper diag with a solution for you that is more reasonable.

    it does need to be attended to as it wont get any better with a proper repair.
