Using the GeekOBD APP, you can connect to your vehicle's OBD2 system, read the P080B code, and check for any accompanying trouble codes. This will help you understand the context and severity of the problem.

What vehicles are most commonly affected by P080B?

The P080B code is commonly found in vehicles like the 2016 Honda Accord and the 2017 Toyota Camry, among others. It's advisable to check for any recalls or technical service bulletins related to your specific model.

How can I prevent P080B from happening again?

Regular maintenance, including checking and replacing the transmission fluid as per the manufacturer's recommendations, can help prevent P080B from recurring. Keeping wiring and connectors clean and free of corrosion is also essential.

What is P080B?

The P080B diagnostic trouble code indicates a performance issue with the transmission range sensor circuit. This sensor, located within the transmission system, is responsible for communicating the position of the gear lever to the vehicle's Engine Control Module (ECM). When the ECM receives an unexpected signal from the range sensor, it triggers the P080B code. This may lead to a range of performance issues, including difficulty in shifting gears or the transmission staying in a single gear. Commonly seen in popular models like the 2016 Honda Accord and the 2017 Toyota Camry, this code can severely impact driving safety and efficiency. If left unaddressed, it could result in further transmission damage, leading to costly repairs. Vehicle owners may notice symptoms such as the 'Check Engine' light illuminating, erratic shifting behavior, or even the inability to shift gears at all. It's crucial for drivers experiencing these symptoms to seek diagnostic assistance promptly to avoid more severe issues down the road.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P080B is present:

  • The 'Check Engine' light remains illuminated, indicating a fault in the transmission range sensor.
  • Drivers may experience erratic shifting, where the transmission unexpectedly shifts up or down, creating a jerky driving experience.
  • Fuel economy may decrease significantly, with reports of up to a 15% reduction in efficiency due to improper gear engagement.
  • In some cases, the vehicle may refuse to shift into certain gears, limiting driving speeds and potentially causing safety hazards.
  • There may be noticeable delays in acceleration when pressing the gas pedal, as the transmission struggles to respond appropriately.

Possible Causes

Most common causes of P080B (ordered by frequency):

  1. The most common cause of the P080B code is a faulty transmission range sensor, accounting for about 60% of cases. This sensor can wear out over time or become damaged from exposure to heat and contaminants.
  2. Another frequent cause is damaged wiring or poor connections in the transmission range sensor circuit. Corrosion or fraying of the wires can disrupt the signal being sent to the ECM.
  3. Less commonly, software issues in the vehicle's ECM can lead to misinterpretation of the sensor's readings. Regular software updates can prevent this.
  4. A malfunctioning transmission control module (TCM) can also cause this code, although this is rarer and usually results from other underlying issues.
  5. In rare instances, a complete transmission failure might trigger the P080B code, indicating severe internal damage that needs immediate attention.
