What is OBD-II Code P08B1 – Neutral Position Sensor B Circuit Intermittent/Erratic



What is OBD-II Code P08B1 – Neutral Position Sensor B Circuit Intermittent/Erratic?

If you’re seeing the OBD-II code P08B1 on your car’s dashboard, it means that there’s a problem with the neutral position sensor B circuit. To understand this code, you first need to know what the neutral position sensor is and what it does.

The neutral position sensor is a part of your car’s transmission system. It’s responsible for monitoring the position of the shift lever in relation to the transmission. It ensures that the transmission is in the correct gear, and it also provides input for other systems in the car, such as the engine control module (ECM).

When the neutral position sensor B circuit is intermittent or erratic, it means that there’s a problem with the electrical circuit that connects the sensor to the ECM. This can happen for a number of reasons, such as a loose or damaged wire, a faulty connection, or a damaged sensor itself.

Symptoms of OBD-II Code P08B1 – Neutral Position Sensor B Circuit Intermittent/Erratic

A car with an intermittent or erratic neutral position sensor B circuit might exhibit a number of symptoms. Some of the most common symptoms include:

– Difficulty shifting gears
