P0714 Acura Code - Transmission Fluid Temperature Sensor Intermittent Failure
Quick Answer
The P0714 code for Acura vehicles indicates a Transmission Fluid Temperature Sensor Intermittent Failure. Common causes include Faulty transmission fluid temperature sensor: The sensor itself may be malfunctioning, providing incorrect readings to the transmission control module, Wiring or connector issues: Loose or damaged wiring or connectors can cause intermittent signal loss from the sensor to the transmission control module, Corroded connections: Corrosion on the sensor connections or wiring can lead to poor electrical conductivity, resulting in intermittent sensor readings. 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 Acura Description
The P0714 code for Acura vehicles indicates a Transmission Fluid Temperature Sensor Intermittent Failure. This code is triggered when the transmission control module detects that the signal from the transmission fluid temperature sensor is not within the expected range or is intermittent. The transmission fluid temperature sensor plays a crucial role in monitoring the temperature of the transmission fluid to ensure proper operation of the transmission system.
Common Causes of P0714 Acura
- Faulty transmission fluid temperature sensor: The sensor itself may be malfunctioning, providing incorrect readings to the transmission control module.
- Wiring or connector issues: Loose or damaged wiring or connectors can cause intermittent signal loss from the sensor to the transmission control module.
- Corroded connections: Corrosion on the sensor connections or wiring can lead to poor electrical conductivity, resulting in intermittent sensor readings.
- Transmission fluid level: Incorrect transmission fluid level can affect the sensor's ability to accurately monitor the temperature of the fluid.
- Internal transmission issues: Problems within the transmission system, such as a failing torque converter or solenoids, can also trigger this code.
Symptoms of P0714 Acura
- Check Engine Light: The most common symptom associated with a P0714 code is the illumination of the Check Engine Light on the dashboard.
- Erratic shifting: The transmission may exhibit erratic shifting behavior, such as harsh shifts, delayed engagement, or slipping.
- Decreased fuel efficiency: A malfunctioning transmission fluid temperature sensor can lead to inefficient transmission operation, resulting in decreased fuel efficiency.
- Transmission overheating: If the sensor provides inaccurate readings, it can lead to transmission fluid overheating, which may cause additional symptoms such as a burning smell or transmission slipping.
- Transmission in limp mode: In some cases, the vehicle's transmission may go into a limp mode to prevent further damage, limiting the vehicle's performance.
How to Fix P0714 Acura
- Diagnose the issue: Use a diagnostic scanner to retrieve the P0714 code and perform a thorough inspection of the transmission fluid temperature sensor, wiring, and connectors.
- Replace the transmission fluid temperature sensor: If the sensor is found to be faulty, replace it with a new sensor following the manufacturer's guidelines.
- Check wiring and connectors: Inspect the wiring and connectors for any damage or corrosion, repair or replace as needed.
- Clear the code: After replacing the sensor and addressing any wiring issues, clear the code from the vehicle's computer using a diagnostic scanner.
- Test drive: Take the vehicle for a test drive to ensure that the transmission operates correctly and that the Check Engine Light does not reappear.
Cost to Fix P0714 Acura
The cost of repairing a P0714 code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. On average, the cost of replacing a transmission fluid temperature sensor ranges from $100 to $200, including parts and labor. Additional costs may be incurred if wiring or connectors need to be repaired or replaced. It's essential to consult with a trusted mechanic or auto repair shop to get an accurate estimate based on your vehicle's make and model, as well as the extent of the repairs required.
