Dodge Ram Throttle Position Sensor Reset (Step-by-Step Guide)

The Dodge Ram is a popular automobile known for its rugged performance and reliability. However, like all vehicles, the Dodge Ram can experience issues with its engine components, including the throttle position sensor (TPS).

Having a faulty TPS can cause a variety of issues, such as poor acceleration and engine stalling.

Fortunately, resetting the TPS can help resolve these problems and restore your vehicle’s performance. With the right tools and knowledge, you can easily reset the TPS on your Dodge Ram in a few simple steps. But don’t know how to do it? No need to worry.

We’ve brought simple steps to help your Dodge RAM throttle position sensor reset.

What Is A Throttle Position Sensor Reset In Dodge Trucks?

Resetting Dodge Ram Throttle Position Sensor, or TPS Reset, involves resetting the throttle position sensor in a Dodge Ram vehicle. Performing this procedure ensures that the throttle is calibrated correctly and operates correctly for the best performance of the RAM truck.

An electronic control module (ECM) controls throttle position and other factors and can be reset by a TPS Reset procedure. Whenever the throttle system has been adjusted or repaired, adjusting the throttle position for alignment with ECM  must be done.

Why And When do You Need to Resetting The Throttle Position Sensor?

A throttle position sensor (TPS) helps the engine control system to monitor the throttle plate’s position within an internal combustion engine. The throttle sensor typically regulates airflow into the engine. After replacing the sensor or repairing an engine, it is usually necessary to reset the TPS position to let the vehicle work like before.

By resetting the throttle position sensor, the engine control unit can relearn the throttle position sensor’s range, thus restoring proper engine operation. But before resetting, you must know whether the throttle in your Dodge RAM needs to reset.

Some clear indications can help the driver easily understand the disturbance in the throttle position. So here are some indications.

Unusual engine idle

A faulty throttle position sensor can cause an unexpected change in engine idle speed, ranging from an unusually high idle to a stalling engine.

Unintended acceleration

When the throttle position sensor is malfunctioning, the engine can accelerate unexpectedly when the vehicle is stationary or while the driver is maintaining a steady speed.

Check engine light

A defective throttle position sensor can cause the “check engine” light to come on.

Poor fuel economy

More use of fuel results in poor fuel economy. Needing to fill the tank more frequently is the common issue indicating that it’s time to reset throttle position.

Reduced power

A malfunctioning throttle position sensor can decrease power and acceleration, making driving difficult. So drivers often get to know about a faulty throttle position with unusual driving issues.

Erratic shifts

When the throttle position sensor fails, the transmission can shift erratically, causing irregular shifts or shifting delays.


The engine will hesitate or stumble when accelerating, causing a loss of power.

Poor start

Fuel injectors may need to receive the correct information to start the engine, resulting in a poor start.

Unusual noises

Unusual noises from the engine, such as whistling or humming.

Increased emissions

Poor throttle position sensors can cause the vehicle’s engine to run less efficiently, causing increased emissions.

How to Resetting Dodge RAM Throttle Position

Procedure for resetting the throttle position in different models of Dodge RAM trucks is almost the same, so you can follow the simple below-mentioned steps to reset the throttle position successfully.

Here are the detailed steps for resetting the throttle position sensor on Dodge trucks

Step #1. Disconnect the negative battery terminal

A qualified mechanic should do this. Before disconnecting the battery terminal, turn the ignition off and disconnect all electrical components from the battery.

Step # 2. Locate the throttle position sensor and disconnect the electrical connector.

Open the hood and locate the throttle position sensor (TPS). It is typically located on the side of the throttle body near the air intake.

Step # 3. Remove the two screws holding the throttle position sensor and remove the sensor from the throttle body.

Locate the two screws that hold the throttle position sensor to the throttle body. Using a head screwdriver, remove the two screws. Carefully pull the throttle position sensor away from the throttle body.

Step # 4. Mount the new throttle position sensor with the two screws.

To install the new sensor, you must locate the two mounting holes on the throttle body and secure the sensor with two screws. Be sure to use the correct size and type of screw, as this is a critical step in ensuring a secure connection.

Step # 5. Start the engine and allow it to idle for a few minutes.

Reconnect the negative battery terminal, turn the ignition switch to the “ON” position, and allow the vehicle to idle for a few minutes.

Step # 6. Test the throttle position sensor to ensure it’s working properly.

The voltage output should be measured at various throttle positions to test the TPS. A multimeter should be used to measure the voltage output at the TPS connector. The voltage should increase or decrease as the throttle position is changed. The TPS is now settled if the voltage output is consistent with throttle position changes.

Why is it important to reset the throttle position sensor?

Incorrectly completing the TPS Reset procedure can result in stalling, poor acceleration, and poor fuel economy with the throttle system.

In addition, the TPS Reset procedure can help to reset the idle speed of the vehicle and should be completed whenever any adjustments have been made to the idle speed.

What is the simplest method to reset the throttle position sensor?

The TPS Reset procedure is relatively simple and can be completed in a few steps.

  • First, the vehicle should be placed in Park, and the engine should be turned off.
  • Next, the negative battery cable should be disconnected, and the positive battery cable should also be disconnected.
  • After this is done, the negative cable should be reconnected, and then the positive cable should be reconnected.
  • Finally, the TPS Reset procedure should be performed.

What are the symptoms of a faulty throttle position sensor in a Dodge Ram?

Common symptoms of a faulty throttle position sensor in a Dodge Ram include engine stalling or running rough at idle, engine hesitation or misfire when accelerating, poor fuel economy, and the Check Engine light coming on.

Final Words

Resetting the Dodge Ram Throttle Position Sensor is important to ensure your vehicle runs optimally. Following a relatively straightforward procedure, you can reset the throttle position in a few minutes.

To ensure proper sensor resetting, follow the instructions in the owner’s manual. Failure to follow the reset procedure may result in the engine not running properly or at all. Therefore, ensuring the reset procedure is done correctly before attempting to drive the vehicle is important.
