WHAT IS THE INDUCTIVE THROTTLE SENSOR?

The inductive throttle sensor is a part installed into your cart’s electrical system and is designed to control your speed. It works along with the speed controller and other similar parts to ensure that you get enough power for your cart whenever you run it. Typically, the throttle sensor is connected to your cart via a wiring harness and is attached directly to the direction sensor. These two parts work together to produce not only the proper speed for your cart but the direction as well. For example, when you press your gas pedal down, an electrical signal gets sent to the inductive throttle sensor to get an idea of how much speed that you want. Once this part receives that signal, it sends an electrical signal to the throttle in the cart to produce the proper speed. Likewise, when you turn your cart’s wheel as you drive, signals get sent to the direction selector that tell your cart into which direction you should turn. These steps occur almost simultaneously when you move your cart and should keep it in good operating order. Like all parts, though, there is a chance that the inductive throttle sensor may wear down and need to be tested and replaced. There are a handful of different ways that you can test this part in your cart.

TESTING METHODS YOU MAY USE

When checking your inductive throttle sensor, you’ll be testing using various items such as Alltrax controllers, a connection with the four-wire Molex plug, or with a proximity detector. There are a few reasons that you want to use each of these testing methods – you usually choose them based on what may be wrong with your cart and what areas of the cart’s electrical system are affected. For example, you use Alltrax controllers to check for problems with the throttle voltage. In some instances, the throttle may not send a proper amount of electricity to your cart or to the sensor, causing it to malfunction. By using these controllers, you get an idea of how much charge is coming through your system and whether or not you need to replace or adjust these parts to keep your cart smooth. And when you use a four-wire Molex plug test, you are checking the wire harness and the throttle box for various types of corrosion and other types of problems. Typically, this test requires you to open up your cart and take a look at your engine’s interior. However, we’ll go over this process in more depth below to give you a better feel for how to properly handle it in your cart. Lastly, the proximity detector is a device you hook up directly to the sensor to see if it is malfunctioning in any way that may require replacement. This process is usually the last one that you try because there are often less severe issues that plague this part. However, when you use the proximity detector, you are looking for problems that may be more persistent and which may require replacing that part.

ALLTRAX CONTROLLER TESTS

The steps below should give you a good idea of what problem is affecting your sensor:

1. Start by jacking up your golf cart to get easier access to this part of the cart’s bottom
2. Identify the six- or 10-pin connector and carefully pull it out so that you can measure the pins
3. Put the key in the “On” position in your Run/Tow switch on the cart
4. Switch the F/R switch into a forward position to test your cart
5. Place your voltimeter testing pins on the throttle pins to see how much voltage you get
6. When the cart is running with no throttle, you should get about 10 volts here
7. Have somebody push the pedal down to the floor and then take the voltage reading again
8. At this point, you should have a reading of six volts or so from your voltimeter
9. Pay attention to the voltage amount if you get higher than 10 at any point here
10. If you have a reading of 12 volts, your sensor is faulty and must be replaced ASAP
11. By contrast, a voltage reading of 14 indicates a broken wire on your throttle

REPLACING THE INDUCTIVE THROTTLE SENSOR

Thankfully, it is fairly easy to replace your inductive throttle sensor following these steps:

1. Take off the rocker panel on the driver’s side of your cart
2. Lift up the floor mat and look for a cutout on the floorboard
3. Remove the cutout and take off the screws from the pedal box
4. Find the inductive throttle sensor and remove its connecting screws
5. Place a new sensor in its place and replace everything you removed
