What is B0713?

The DTC (Diagnostic Trouble Code) B0713 indicates a problem with the transmission fluid temperature sensor circuit. This code is commonly found in several vehicle models, particularly in the 2015-2018 Honda Accord and the 2016-2019 Toyota Camry. The transmission fluid temperature sensor plays a crucial role in monitoring the heat of the transmission fluid, which is essential for optimal transmission performance. When the sensor detects a temperature that is outside the expected range, it triggers the B0713 code. This can lead to poor shifting behavior, increased wear on transmission components, and potentially severe damage if left unaddressed. If you notice this code, it's imperative to act quickly to avoid costly repairs. A vehicle experiencing this issue may exhibit erratic shifting, slipping, or even a complete transmission failure in severe cases. Addressing the B0713 code involves not only fixing the sensor but also ensuring the wiring and connections are intact. Regular maintenance and checks of the transmission fluid can help prevent this issue from arising in the first place.

Symptoms

Common symptoms when B0713 is present:

  • Check engine light illuminates, often staying on continuously until the issue is resolved.
  • Transmission may hesitate or experience rough shifting, leading to a noticeable delay when changing gears during normal driving.
  • Fuel economy could decrease significantly, sometimes by 10-15%, due to improper transmission function.
  • Unusual transmission fluid smell, indicating overheating and potential damage.
  • Inconsistent transmission performance, with slipping or abrupt changes in gear engagement.

Possible Causes

Most common causes of B0713 (ordered by frequency):

  1. Faulty transmission fluid temperature sensor (around 60% likelihood) - The sensor can fail due to wear or internal faults, resulting in inaccurate readings.
  2. Wiring issues (25% likelihood) - Damaged wiring or poor connections in the sensor circuit can cause signal interruptions, triggering the code.
  3. Poor transmission maintenance (10% likelihood) - Neglecting regular fluid changes can lead to contamination and overheating.
  4. Overheating transmission (4% likelihood) - An underlying issue causing high fluid temperatures may also trigger this code.
  5. Rarely, failed Engine Control Unit (ECU) (1% likelihood) - While unlikely, a malfunctioning ECU may misinterpret sensor data.
