6 Pin Throttle Position Sensor Wiring Diagram

The throttle position sensor (TPS) is an integral part of an engine. When the throttle is open, it senses the position of the plate and relays a signal to the computer, which controls the fuel injection. When the throttle is closed, the sensor senses the position of the plate and relays a signal to the engine’s electronic control unit, which can adjust the timing and fuel delivery.

In this article, we will talk about the wiring diagram of the throttle position sensor and the electronic throttle body. This diagram will teach you how to install and operate the sensor.

The sensor’s wiring can change depending on the model, make, and year of the vehicle. The manufacturer of the vehicle will usually design the wiring of the sensor based on your specific requirements. This guide will give you a general idea about how the sensor is built.

Your vehicle’s owner’s manual will also give you the necessary details about the type of wires that are connected to the sensor. The colors of the wires will vary depending on the brand of the sensor.

6 Pin Throttle Position Sensor Wiring Diagram (drive by wire throttle)

There are two types of throttle bodies that have 6-pin wiring. The first is an electronic throttle body, while the second is a cable-operated throttle body.

  • Motor Negative
  • Motor Positive
  • Signal Wire (Sensor 1)
  • Signal Wire (Sensor 2)
  • Ground Wire
  • Hot Power Wire (5 Volt Reference voltage comes from the ECU)

A six-pin electronic throttle body has two potentiometers and one motor. It has six wires, and two of these are earth and hot wires. The other wires are used for signals and the motor. The common ground and hot wires on these six-pin sensors are shared.

The power supply for the sensor is provided by the car’s computer, which is referred to as the engine control unit. The 5-volt reference voltage coming from the hot wire is used to power the sensor.

The ground wire of the two sensors is taken from the engine control unit. The third wire is used to provide the signal to the sensor. The throttle position sensor receives input from this wire.

A throttle position sensor with six pins and cable operation has two potentiometers. Separate ground, signal, and hot wires are used to connect these components to the computer. The remaining wires serve as signals and motor connections.

One of the six-pin throttle position sensors has redundant components. This means that if one of the sensors fails, the other will still function. This feature helps ensure that the position sensor will still function properly even if it is not working properly. It’s like having two eyes that can still see if one is damaged.
