Why is the speedometer on my VW Golf not working?
If your Volkswagen Golf’s speedometer is not working, it’s usually going to be caused by an issue with the VSS (vehicle speed sensor), or a bad ECU. The VSS is usually not very expensive, and they are not that difficult to replace.

How do I test the VSS on my engine?
Start by disconnecting and removing the VSS from your engine so you can test it. You can then connect it to a multimeter and set the multimeter to the AC setting.
How do I know if my speed sensor is bad?
If your speed sensor is good, you should hear a beep and experience resistance to the pushing action by slowing down. If the sensor is bad, your cart will start rolling. Remember that if the switch is in Tow position, the cart will definitely roll.
How do I know if my speed sensor is working?
One of the most common signs of a bad speed sensor is abnormal automatic transmission operation. If the VSS is faulty, the transmission may exhibit symptoms such as delayed shifts, hard shifts, and limited gear operation.

Which sensor is used to detect engine speed?
The speed sensor measures gear or target wheel speed and position. The Engine Control Module can use this information to modify various engine functions such as Air/Fuel Ratio, ignition timing and perform diagnostic tests.
What sensor indicates engine speed in RPM?
A tachometer is an instrument that measures the working speed of an engine, typically in revolutions per minute (RPM). It is commonly used in cars, boats, planes, and other vehicles. Most tachometer gauges have either an analog (dial) or digital (LCD or LED screen) display.

How do you test a speed sensor on a car?
Connect the VSS to a power drill so you can simulate the rotation of the vehicle's transmission and read the multimeter to see if the voltage increases as the speed increases to check if the sensor is working properly.
What is engine speed sensor circuit malfunction?
If the input speed sensor fails, it means your car does not know how fast it is moving, which can cause many systems to fail. The symptoms can include: Failure to shift gears. Malfunctioning speedometer. Malfunctioning tachometer.
Can a speed sensor stop a car from starting?
In fact, most sensors are responsible for actually making the changes to critical systems such as ignition and fuel systems. Since any engine requires the correct air to fuel ratio and ignition timing to start, having a faulty sensor that can't adjust these symptoms on the fly can cause the engine to not start.
What is the difference between vehicle speed sensor and transmission speed sensor?
A vehicle speed sensor (VSS) is a small component mounted on your car's transmission that lets the car's onboard computer know how fast you're moving. It's also known as a wheel speed sensor, transmission speed sensor, or output shaft speed sensor.
What happens if I disconnect the speed sensor?
If it's the wheel speed sensors (like for the ABS) the car will run but the ABS system won't be able to do its job. If we're talking about any engine sensors, the engine MIGHT still run, but it will likely run poorly or throw a check engine light.
How do I reset my speed sensor?

How to test a speed sensor on a golf cart?
Two methods of testing your speed sensor are the following: Activate the Run/Tow switch of the golf cart by keeping it in Run position and try to push the cart.
Why does my golf cart stutter?
Your golf cart may move very slowly as if it’s creeping along or it may move at an erratic speed. You may experience stuttering in your golf cart like when you have a bad battery or there is a low voltage problem. A broken or damaged magnet on the motor can result in a bad speed sensor.
Why does my golf cart roll off?
Roll-away protection is essential for the safety of the golf cart. If the parking brake is not activated, the golf cart tends to roll off when it is in a neutral position and stopped in an incline. Please note that rolling will occur in neutral only at a predetermined speed.
Can a golf cart go fast?
Your golf cart may go fast initially and slow down drastically on its own after some time. This will happen repeatedly in a cyclic pattern. In such a situation, the car is said to be in limp-mode. You can do a roll-away test to check your golf cart speed sensor.
Can you fix a golf cart on your own?

How to test a vehicle sensor?
1. Find a drill bit that fits securely into the VSS. In order to simulate the movement of your vehicle to properly test the sensor, you need to rotate the gear inside of the VSS. Insert drill bits into the gear slot on the VSS until you find one that fits securely into it .
How to locate VSS sensor?
Locate the VSS sensor near the transmission of your vehicle. Find the transmission dipstick and follow it to locate your transmission. The VSS will be a small sensor attached to your transmission by 2 wires and held in place by a bracket. It will also have a sliding pull tab on it.
How to tell if a VSS is working correctly?
If the VSS is functioning correctly, the voltage on the multimeter will increase as the speed of the VSS rotation increases.
How to test VSS?
Set the multimeter to AC to test your VSS. Look for a dial on your multimeter that has numbers and letters on it. The AC, or alternating current, setting may be labeled as AC, V with a squiggly line, or ACV. Turn the dial until the arrow or indicating line is pointing to the AC setting.
What is a VSS sensor?
A vehicle speed sensor, or VSS, is a sensor that is used to determine how fast your vehicle is traveling. If your vehicle’s speedometer stops working or isn’t telling you the correct speed that you’re traveling, you likely have a faulty VSS.
How to get a VSS out of a car?
1. Make sure the vehicle is turned off to avoid being shocked. Put the vehicle in park on level ground and turn off any lights or accessories that may draw power from the battery. Remove the key from the engine to make sure it’s completely turned off. Parking on level ground makes it easier for you to access the VSS.
Where is the wiring harness located on a VSS?
Unplug the harness so you can take out the sensor. The wiring harness may be located on the underside of the VSS.
What is a speedometer on a golf?
A modern vehicle’s speedometer takes the input from the Vehicle Speed Sensor and sends that data to the ECU. The ECU is programmed with your Golf’s gear ratios and stock tire height. It combines this data to send the speed reading to the instrument cluster. The causes of a bad speedometer will typically be found in these four things:
What is the connection between the drivetrain and the speedometer?
Vehicles used to use a cable that would usually run from the tail shaft of the transmission to the speedometer. There was a physical/mechanical connection between the drivetrain and the speedometer. Instead of this direct connection, a modern vehicle uses the vehicle speed sensor and relays that information to the speedometer.
What is an ECU golf?
ECU – Your Golf’s Engine Control Unit (ECU for short) is the computer that takes all of the information that the vehicle sensors compile and uses it to control the vehicle systems, and sends important vehicular telemetry data to the driver via the instrument cluster.
What does a speed sensor do?
The speed sensor does more than just control the speedometer, it also helps to control the cruise control system and may even affect the way that the engine runs. If the service engine soon light is on, then check the trouble code with an OBDII scanner.
What does it mean when a speedometer goes out?
Most of the time if the speedometer is out, it means that there is a bigger problem with the entire instrument cluster.
