What is B07E1?

DTC B07E1 signifies a problem related to the transmission control module (TCM) or the associated wiring and sensors. This code indicates that the TCM has detected an issue with the transmission, which may lead to erratic shifting, slipping, or even complete loss of power in some instances. When this trouble code triggers, it typically means that the vehicle's computer has identified a fault in the circuit related to the transmission fluid temperature sensor or the transmission range sensor. These sensors play a crucial role in ensuring that the transmission operates smoothly by providing real-time data to the TCM. If these sensors fail or if there is a wiring issue, it can lead to significant driving disruptions, affecting overall vehicle performance and safety. Owners of vehicles like the 2015-2018 Honda Accord or Toyota Camry may notice symptoms such as the check engine light illuminating, harsh shifting, or delayed engagement when the vehicle is put into gear. Ignoring this code can lead to more severe transmission problems and costly repairs down the line, making it essential for vehicle owners to understand what B07E1 means and how to address it promptly.

Symptoms

Common symptoms when B07E1 is present:

  • Check engine light stays on constantly, indicating a persistent issue with the transmission system.
  • Engine hesitates during acceleration, leading to a rough driving experience and potential safety concerns.
  • Fuel economy decreased by 10-15%, which can be frustrating and costly over time as fuel prices rise.
  • Harsh or erratic shifting, making it uncomfortable to drive, especially during stop-and-go traffic.
  • Delayed engagement when shifting into gear, causing uncertainty and hesitation while driving.

Possible Causes

Most common causes of B07E1 (ordered by frequency):

  1. Faulty transmission fluid temperature sensor - Approximately 60% of B07E1 cases are due to a malfunction in this sensor, causing incorrect readings that affect transmission performance.
  2. Wiring issues - Damaged or corroded wiring related to the TCM or sensors can cause signal loss; this is often found in older vehicles, especially those exposed to harsh environments.
  3. Failed transmission range sensor - This sensor ensures that the transmission is in the correct gear; failure can lead to improper shifting and is relatively common in vehicles with high mileage.
  4. Less common but serious cause: TCM failure - This is a critical component that can fail due to internal faults, leading to complete loss of transmission control.
  5. Rare but possible cause: Software glitches - Occasionally, outdated software in the vehicle's control module can trigger false codes, necessitating an update.
