P0714 Subaru Code - Transmission Fluid Temperature Sensor Intermittent

Quick Answer

The ATF (Automatic Transmission Fluid) Temperature Sensor converts the fluid temperature into a resistance value. Common causes include Faulty Transmission Fluid Temperature Sensor, Transmission Fluid Temperature Sensor harness is open or shorted, 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 P0714 Subaru Description

The ATF (Automatic Transmission Fluid) Temperature Sensor converts the fluid temperature into a resistance value. The sensor resistance changes with the transmission fluid temperature. As the temperature becomes higher, the sensor resistance decreases. The Transmission Control Module (TCM) monitors the ATF (Automatic Transmission Fluid) Temperature Sensor signal. The TCM sets the OBDII code when the ATF (Automatic Transmission Fluid) Temperature Sensor signal is out of factory specifications.

Frequently Asked Questions about P0714 Subaru Code

1. What does the OBDII code P0714 mean for a Subaru?

P0714 indicates an intermittent issue with the transmission fluid temperature sensor, which monitors the fluid temperature for proper transmission operation.

2. What are the common symptoms of code P0714 in a Subaru?

Symptoms may include erratic or delayed shifting, transmission overheating, poor fuel efficiency, or the activation of the check engine light.

3. What causes the P0714 code to appear in a Subaru?

Causes can include a faulty transmission fluid temperature sensor, damaged wiring or connectors, low or dirty transmission fluid, or a failing transmission control module (TCM).

4. Can I drive my Subaru with a P0714 code?

Driving with this code is not recommended, as it may lead to further transmission damage or reduced vehicle performance.

5. How can I diagnose the P0714 code in a Subaru?

Diagnosis involves checking the transmission fluid level and condition, inspecting the sensor and its wiring for damage, and using a scan tool to monitor temperature sensor readings.

6. How do I fix the P0714 code on my Subaru?

Repairs may include replacing the faulty temperature sensor, repairing or replacing damaged wiring, cleaning or replacing the transmission fluid, or reprogramming the TCM if needed.

7. How much does it cost to fix a P0714 code on a Subaru?

Repair costs vary but typically range from $100 to $300 for sensor replacement. Additional costs may apply if wiring or transmission fluid issues are involved.

8. Can low transmission fluid cause a P0714 code in my Subaru?

Yes, low or contaminated transmission fluid can trigger this code by causing the sensor to provide inaccurate readings.

9. Where is the transmission fluid temperature sensor located on a Subaru?

The sensor is usually located inside the transmission or on the transmission valve body, depending on the model.

10. Will clearing the P0714 code fix the issue permanently?

Clearing the code will temporarily turn off the check engine light, but it wonâ€™t resolve the underlying problem causing the code. Proper diagnosis and repair are necessary.
