Car Fix Episode: Manual Transmission Neutral Switch

Introduction

In this episode of Car Fix, we’re going to be taking a look at the manual transmission neutral switch. The neutral switch is a small but important component that tells the car’s computer when the transmission is in neutral. This information is used to control a number of different functions, including the starter, the cruise control, and the reverse lights.

When the neutral switch fails, it can cause a number of different problems. The most common symptom is that the car will not start. Other symptoms can include the cruise control not working, the reverse lights not coming on, or the car stalling when it is put into gear.

Symptoms of a Bad Neutral Switch

• The car will not start.
• The cruise control does not work.
• The reverse lights do not come on.
• The car stalls when it is put into gear.

Causes of a Bad Neutral Switch

• Wear and tear.

Diagnosing a Bad Neutral Switch

To diagnose a bad neutral switch, you will need to use a multimeter to test the continuity of the switch. To do this, follow these steps:

1. Disconnect the negative battery terminal.
2. Locate the neutral switch. It is usually located on the side of the transmission.
3. Set your multimeter to the ohms setting.
4. Touch one probe of the multimeter to one of the terminals on the neutral switch.
5. Touch the other probe of the multimeter to the other terminal on the neutral switch.
6. If the multimeter reads continuity, then the neutral switch is good.
7. If the multimeter does not read continuity, then the neutral switch is bad.
