The Dodge Ram is one of the standout models in the Dodge lineup. With its massive towing capacity, spacious interior passenger volume, and fantastic speed, this monster will optimize your riding experience all day.
But after a few years or due to some unhealthy maintenance culture, your Ram may start to slow down.
This article provides you with detailed answers to all that you need to know about the Dodge Ram throttle position sensor reset. Shall we get started?
What is the Throttle Position Sensor (TPS)?
With just a push of your accelerator pedal, you are relaxed as your Dodge Ram roars to life with full potential. Do you know what actually translates your foot’s commands into the perfect balance of air and fuel? It is a little but mighty sensor called the Throttle Position Sensor. In this guide, I’ll be giving it a fancy abbreviation TPS.
The TPS monitors the position of the throttle pedal and sends signals to the engine control unit (ECU) to adjust the air-fuel mixture and control the engine’s performance. The sensor mainly informs the ECU of the driver’s throttle input. The ECU then determines the amount of air and fuel that should go into the engine. This process is needed to help your vehicle idle and accelerate without stress.
In a Dodge Ram, you can find the TPS on the throttle body. It connects to the throttle shaft and it is linked to the vehicle’s wiring harness through electrical connectors.
Of course, like every other auto part, the TPS can become faulty. Then it becomes important for you to replace it to restore your vehicle to its full performance and power. But then, what are the possible causes of TPS failure?
Throttle Position Sensor Failure- Why?
You will probably come across a defective TPS later on if the TPS has been subjected to excessive amounts of engine fluids, dirt, or debris.
Throttle Position Sensors, like all other auto components, degrade with time and frequently need a replacement over time.
If your Dodge Ram hasn’t been serviced, a defective TPS will definitely show up sooner rather than later.
Additionally, corroded connections or faulty cabling might cause electrical issues that interfere with TPS operation.
Inadequate installation, manufacturer flaws, excessive engine bay heat, poor installation, and environmental variables including harsh weather are other contributing reasons.
7 Common Signs of a Bad Throttle Position Sensor
Automobile issues are as wide as the sands of the sea. Even for those who keep an eye out for any malfunction, it may still be challenging to figure out where the problem comes from. Here are some common signs your vehicle gives when your TPS is begging for help.
- Power Loss and Acceleration Problem
- Poor Fuel Economy
- Rough Or Bad Start
- Erratic Idle
- Surging While Driving
- Check the Engine Light On
How Can I Reset My Dodge Ram Throttle Position Sensor?
Now, here’s the step-by-step guide to get things done ASAP. You can engage in a DIY method. Otherwise, hiring a certified technician will be the best bet.
- Turn the ignition to the “on” position, but do not start the engine.
- Wait for all warning lights on the dash to turn off, except the check engine light – it may stay on.
- Slowly press down the accelerator pedal all the way to the floor, then slowly release it back up.
- Turn the ignition off.
- Repeat steps 1-4 two or three times. This allows the computer to re-learn the zero throttle position.
- Start the engine and let it idle for a few minutes.
- Take the vehicle for a test drive. Accelerate moderately to re-learn the wide open throttle position.
- The computer will now have re-calibrated the full range of motion of the throttle body and throttle response should be improved.
- If throttle response does not seem better, repeat the entire process.
TPS Removal and Installation: Some Helpful Tips
Here are some of the helpful tips you can use to remove and install the throttle position sensor.
- To prevent electrical shorts from happening, start by disconnecting the negative battery cable.
- Then, take off the air intake duct to improve access to the throttle body and its sensor. To detach the duct, gently loosen the clamps and slide it out.
- After gaining access to the throttle body, proceed to uninstall the Throttle Position Sensor. Simply unscrew the sensor and gently remove it.
- Finally, install the new Throttle Position Sensor. Carefully screw in the new sensor and reconnect the negative battery cable.
The TPS is an important part needed for your car’s performance. As soon as you detect any problem with the TPS, you shouldn’t drive for long. Although the problems may appear minor at first, ignoring them may lead to complicated issues. This may, in turn, cause severe damage to your car.
Therefore, do not wait until your mechanic hands you an expensive bill or your wallet begins to call you “Mr. Empty” before you tackle the problem. Whether you’re a DIY enthusiast or you’re entrusting the task to a technician, never forget that the compass to a smooth and efficient vehicle is a well-maintained TPS.
