P0714 Honda Code - Transmission Fluid Temperature Sensor Intermittent Failure
Quick Answer
The Transmission Fluid Temperature Sensor is a thermistor-type sensor that changes resistance according to the change in transmission fluid temperature. 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.

Frequently Asked Questions about P0714 Honda Code
What does the OBDII code P0714 mean on a Honda?
P0714 indicates an intermittent failure in the transmission fluid temperature (TFT) sensor, which monitors the temperature of the transmission fluid.
What are the symptoms of a P0714 code on a Honda?
Symptoms may include erratic shifting, transmission overheating, poor fuel economy, or the Check Engine Light being illuminated.
What causes the P0714 code to appear on a Honda?
Common causes include a faulty TFT sensor, damaged wiring or connectors, low transmission fluid levels, or a malfunctioning powertrain control module (PCM).
Can I drive my Honda with a P0714 code?
Driving with a P0714 code is not recommended as it can lead to transmission damage, especially if the fluid temperature is not properly monitored.
How do I fix the P0714 code on my Honda?
Repairs may include replacing the TFT sensor, repairing damaged wiring, ensuring proper transmission fluid levels, or reprogramming the PCM if necessary.
How do I diagnose a P0714 code on a Honda?
Diagnosis involves using an OBDII scanner to verify the code, inspecting the TFT sensor and its wiring for damage, and checking the transmission fluid level and condition.
What tools are needed to repair a P0714 code on a Honda?
Common tools include an OBDII scanner, multimeter for electrical testing, basic hand tools, and potentially a transmission fluid drain and fill kit.
How much does it cost to repair a P0714 code on a Honda?
The cost varies but typically ranges from $100 to $300, depending on whether the sensor or wiring needs replacement and labor rates.
Can low transmission fluid cause a P0714 code on a Honda?
Yes, low or degraded transmission fluid can cause issues with the TFT sensor and trigger the P0714 code.
Does the P0714 code always mean the TFT sensor is bad?
No, the code can also be caused by wiring issues, PCM problems, or fluid-related issues, so proper diagnosis is essential.

I have a 2019 Civic w/ a CVT transmission. I have a OBD11 P0714 code but was told this car does not have a Transmission Temp sensor. Can you confirm and if I am incorrect can you direct me to the sensor. Also, if this is correct how do I correct the code as it will not reset.
Thanks

The P0714 code on your 2019 Honda Civic is related to the Transmission Fluid Temperature Sensor Circuit, specifically indicating that it has an intermittent issue. Despite being told that your vehicle does not have a Transmission Fluid Temperature Sensor, the presence of this code suggests otherwise. The solenoid wire harness and the transmission fluid temperature sensor are not available separately. Replace them as a set.
Here are potential solutions to resolve the P0714 code:
-
Check and replace the transmission fluid temperature sensor (40% probability)
- If the sensor is faulty or damaged, it could be causing intermittent readings. In some Honda models, this sensor is integrated into the transmission assembly, which may be why it's not easily identifiable.
-
Inspect and repair wiring and connectors (30% probability)
- Damaged or corroded wiring connected to the sensor could result in intermittent signals, triggering the code. Look for loose connections or frayed wiring near the transmission area.
-
Check and replace the Transmission Control Module (TCM) (15% probability)
- The TCM could be sending incorrect signals due to malfunction, leading to intermittent sensor readings.
-
Update or reflash the TCM software (10% probability)
- Software issues can cause erratic readings from the sensor, and a TCM reflash might resolve the issue.
-
Inspect and replace the transmission fluid (5% probability)
- If the transmission fluid is contaminated or degraded, it might affect sensor readings. This is a low-probability fix but worth checking.
Next Steps:
- Start by inspecting the wiring and connections around the transmission.
- If no wiring issues are found, proceed to locate and test the sensor or have a technician check the TCM for faults or software updates.
This should help you narrow down the issue and clear the P0714 code. If the code persists, it might require more in-depth diagnostics on the TCM.
