P0712 2017 Toyota RAV4 Code - Transmission Fluid Temperature Sensor 'A' Low Input
Quick Answer
The Automatic Transmission Fluid (ATF) Temperature Sensor converts the fluid temperature into a resistance value for use by the Engine Control Module (ECM). Common causes include Faulty Automatic Transmission Fluid (ATF) Temperature Sensor, Automatic Transmission Fluid Temperature Sensor harness is open or shorted, Automatic Transmission Fluid Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0712 2017 Toyota RAV4 Description
This Diagnostic Trouble Code (DTC) indicates an open or short in the ATF temperature sensor circuit. The ATF temperature sensor converts ATF temperature into an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an open or short in the ATF temperature circuit. If the resistance value of the ATF temperature is below 79 Ω*1 or higher than 156 kΩ*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will turn on the MIL and store the DTC.
What are the Possible Causes of the DTC P0712 2017 Toyota RAV4?
- Faulty Automatic Transmission Fluid (ATF) Temperature Sensor
- Automatic Transmission Fluid Temperature Sensor harness is open or shorted
- Automatic Transmission Fluid Temperature Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0712 2017 Toyota RAV4?

2. What are the common symptoms of code P0712 on a 2017 Toyota RAV4?
Symptoms may include erratic shifting, transmission overheating, poor fuel efficiency, or the vehicle entering limp mode.
3. What causes the P0712 code to appear on a 2017 Toyota RAV4?
Common causes include a faulty transmission fluid temperature sensor, damaged wiring or connectors, low transmission fluid, or a malfunctioning ECU.
4. Can I drive my 2017 Toyota RAV4 with code P0712?
Driving with this code is not recommended, as it may lead to transmission overheating or failure if not addressed promptly.
5. How do I fix the P0712 code on a 2017 Toyota RAV4?
Repairs may involve replacing the transmission fluid temperature sensor, repairing or replacing damaged wiring, or ensuring the transmission fluid is at the correct level and in good condition.
6. How much does it cost to repair the P0712 code on a 2017 Toyota RAV4?
Repairs typically cost between $150 and $400, depending on whether the issue is with the sensor, wiring, or fluid, and labor rates in your area.
7. Can a low transmission fluid level trigger the P0712 code?
Yes, low or degraded transmission fluid can cause the sensor to read inaccurately, potentially triggering the P0712 code.
8. How can I check the transmission fluid temperature sensor on my 2017 Toyota RAV4?
You can use a multimeter to test the sensor's resistance and compare it to the manufacturer’s specifications, or use a scan tool to monitor the sensor’s live data.
9. Will clearing the P0712 code fix the issue on a 2017 Toyota RAV4?
Clearing the code will temporarily remove it, but the underlying issue must be resolved, or the code will likely return.
10. Is it necessary to replace the transmission fluid when fixing code P0712 on a 2017 Toyota RAV4?
It may be necessary if the fluid is dirty or degraded, as contaminated fluid can affect sensor readings and transmission performance.
