It's advisable to get an accurate diagnosis to understand the specific issue affecting your vehicle.

Can I drive my car with B0705 or should I stop immediately?

Driving with a B0705 code is risky. If your vehicle exhibits symptoms like harsh shifting or failing to start, it’s best to stop driving and have it checked immediately to prevent potential transmission damage or safety hazards.

How can I diagnose B0705 myself using GeekOBD APP?

Using the GeekOBD APP, you can perform an OBD2 scan to retrieve the B0705 code and any related codes. The app can also provide freeze frame data to help you understand the conditions under which the code appeared. This information is crucial for pinpointing the fault.

What vehicles are most commonly affected by B0705?

The B0705 code is frequently reported in 2008-2012 Honda Accord models and 2010-2015 Toyota Camry. Other makes and models may also be affected, so it’s essential to consult your vehicle's service manual or a professional mechanic.

How can I prevent B0705 from happening again?

To prevent the B0705 code from recurring, ensure regular transmission fluid changes, inspect wiring and connectors for damage, and have your transmission system checked during routine maintenance. Keeping an eye on any unusual symptoms can also help catch issues early.

What is B0705?

The diagnostic trouble code (DTC) B0705 indicates a malfunction in the transmission range sensor circuit, which plays a crucial role in determining the position of the transmission gear. This code typically surfaces when the Transmission Control Module (TCM) detects an inconsistency between the current gear position and what the sensor reports. When this happens, the engine may struggle to shift gears, leading to potential drivability issues such as slipping or harsh shifting. The transmission range sensor, also known as the neutral safety switch, is vital for ensuring that the vehicle can only be started in 'Park' or 'Neutral' positions. A malfunctioning sensor can lead to unexpected vehicle behavior, such as starting in gear or failing to go into certain gears, which poses safety risks. It's essential for car owners to address this issue promptly, as ignoring it may result in more severe transmission problems down the line. This code is frequently found in models such as the 2008-2012 Honda Accord and the 2010-2015 Toyota Camry, among others. Owners experiencing issues related to this code should seek diagnostics and repairs quickly to avoid further complications.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B0705 is present:

  • Check engine light stays on constantly, indicating a need for immediate diagnostics.
  • Transmission may not shift smoothly, leading to noticeable hesitations during acceleration.
  • Vehicle may fail to start in 'Park' or 'Neutral', causing frustration and safety concerns.
  • Unexpected gear selection, with the car shifting into gears without driver input.
  • Decreased fuel economy due to improper shifting patterns, leading to potential over-revving of the engine.

Possible Causes

Most common causes of B0705 (ordered by frequency):

  1. Faulty transmission range sensor - 60% likelihood. This is the most common issue, often due to wear and tear over time.
  2. Wiring or connector issues - 20% likelihood. Damaged wires or loose connections can interrupt the sensor's signals to the TCM.
  3. Faulty TCM - 10% likelihood. If the TCM itself is malfunctioning, it may misinterpret signals from the transmission range sensor.
  4. Low transmission fluid - 5% likelihood. Insufficient fluid can affect transmission performance, leading to erroneous readings.
  5. Severe mechanical issues within the transmission - 5% likelihood. Rare but can cause significant problems if not addressed.
