While you may be able to drive short distances, it's important to avoid prolonged driving as it can exacerbate transmission problems. Immediate attention is advised to prevent further damage.
How can I diagnose P2714 myself using GeekOBD APP?
You can use the GeekOBD APP to scan for codes, view freeze frame data, and monitor the performance of the transmission fluid temperature sensor. Look for abnormal readings that could indicate a fault.
What vehicles are most commonly affected by P2714?
This code is frequently reported in 2015-2018 Honda Accord and Acura TLX models, among others. Checking for any recalls or technical service bulletins (TSBs) related to your vehicle can also be beneficial.
How can I prevent P2714 from happening again?
Regular maintenance, including checking and replacing transmission fluid as needed, can help prevent issues. Ensure all electrical connections are secure and inspect for corrosion periodically.
What is P2714?
The Diagnostic Trouble Code (DTC) P2714 refers to a problem with the transmission fluid temperature sensor range/performance issue, particularly within the context of automatic transmissions. This code is most frequently encountered in Honda and Acura vehicles, especially models produced between 2015 and 2018, such as the Honda Accord and Acura TLX. When this code is triggered, it indicates that the vehicle's engine control module (ECM) has detected that the transmission fluid temperature sensor is not operating within the expected range. In practical terms, this could lead to overheating of the transmission fluid, which can severely impact the performance and longevity of your vehicle's transmission system. If left unaddressed, you may experience slipping gears, erratic shifting, or complete transmission failure, translating to expensive repairs. It is essential for vehicle owners to recognize this code's implications not only for immediate driving performance but also for the overall health of their vehicle. Understanding P2714 can help you take proactive steps to address potential issues before they escalate, ensuring your vehicle remains reliable and efficient.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P2714 is present:
- The check engine light illuminates and remains on, signaling an issue that requires attention.
- You may notice engine hesitations or jerking during acceleration, indicating potential transmission problems.
- Fuel economy may decrease significantly, by about 10-15%, as the transmission struggles to operate efficiently.
- The vehicle may experience harsh or erratic shifting, particularly when changing gears.
- In severe cases, you may notice slipping gears or a complete inability to shift into certain gears.
Possible Causes
Most common causes of P2714 (ordered by frequency):
- The most common cause of P2714 is a faulty transmission fluid temperature sensor, with a likelihood of about 60%. This sensor may fail due to wear and tear or electrical issues.
- Another potential cause is low transmission fluid levels, which can lead to overheating and sensor malfunctions. Maintaining proper fluid levels is crucial for smooth operation.
- Wiring issues or damaged connectors can also trigger this code, leading to intermittent sensor readings. Regular inspections can help prevent this.
- Less commonly, a failing transmission control module (TCM) may be the source of the problem, affecting how the vehicle responds to temperature readings.
- In rare cases, severe transmission damage may cause erroneous sensor readings, necessitating extensive repairs or replacements.

- Address the issue promptly to prevent more expensive secondary damage
Diagnostic Steps
Professional P2714 Diagnosis Process
Follow these systematic steps to accurately diagnose P2714. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Conduct an initial visual inspection of the transmission wiring harness and connectors for any signs of damage or corrosion (5-10 minutes)
Step 2: Use the GeekOBD APP to scan for all diagnostic trouble codes and retrieve freeze frame data for context on the fault (10-15 minutes)
Step 3: Perform component testing on the transmission fluid temperature sensor using a multimeter to check voltage and resistance (20-30 minutes)
Step 4: Conduct a system function test to ensure proper operation after repairs and clear any existing codes (10-15 minutes)
Step 5: Road test the vehicle under various conditions to confirm that the P2714 code does not return and that shifting is smooth (15-20 minutes)
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
