6.7 cummins service electronic throttle control reset

Dodge Ram uses throttle position sensors to monitor the position of the throttle. The computer uses this information to adjust the fuel mixture and ignition timing.

If the sensor is not working properly, the engine will run poorly. You may notice a decrease in fuel economy and an increase in emissions.

To reset the Dodge Ram throttle position sensor, set the ignition key to the On position, then slowly press down the gas pedal until it reaches the floor. Hold the pedal in this position for about 30 seconds, turn the key to the Off position and wait a couple of minutes before starting the engine.

The throttle position sensor (TPS) is a crucial part of the electronic throttle control (ETC) system in modern vehicles. The sensor mainly regulates the air intake and fuel getting into the engine.

In order for the engine to operate smoothly and efficiently, the correct mixture of air and fuel must be delivered constantly. The TPS monitors the position of the throttle butterfly valve and sends a voltage signal to the engine control unit (ECU).

The ECU then uses this information to make necessary adjustments in order to maintain optimal engine performance. Not all vehicles use the TPS for engine management, but it’s a fairly common system.

How the TPS Works on the Dodge Ram

The Throttle Position Sensor is usually mounted on the throttle body and it consists of two parts: a potentiometer and a switch.

As the throttle is opened, the butterfly valve allows more air to enter into the engine. This movement is transferred to the TPS through a linkage.

The potentiometer part of the sensor measures the angle of the throttle and sends a corresponding signal to the ECU.

On the other hand, the switch is used as a backup in case the potentiometer fails. It’s usually only activated when the throttle is in the wide-open position (WOT).

Symptoms of a Bad Throttle Position Sensor

You can usually tell when the TPS is going bad because the engine will start to run erratically. Here are some common symptoms of a failing Throttle Position Sensor:

1. The Check Engine Light Is On

The check engine light on a Dodge Ram is meant to notify the driver that there’s a problem with the vehicle. One of the reasons why the check engine light may come on is because of a faulty Throttle Position Sensor.

When the check engine lights come on you can use an OBD2 sensor to read the codes. The Dodge Ram codes will read as P0123 or P0121.

2. Erratic Idling

Another common symptom of a bad TPS is erratic idling. This usually happens when the sensor is not sending the correct signal to the ECU. As a result, the engine will run lean or rich and will often stall.

3. Engine Stalls or Misfiring

Sometimes you might notice that the engine stalls or misfires when you’re coming to a stop. This is often caused by a faulty Throttle Position Sensor.

When the TPS fails it can cause the engine to run lean or rich. As a result, the engine will stall or misfire when you’re trying to decelerate.

4. Limp Mode

Limp mode is another safety feature on the Dodge Ram that is activated when there’s a problem with the vehicle.

When the limp mode engages, the engine will only be able to run at a limited amount of power. This is done in order to prevent further damage to the engine.

How to Replace Throttle Position Sensor

When the TPS in your Dodge Ram is malfunctioning, the best thing to do is to replace it. Fortunately, this is a fairly easy process and it can be done in about 30 minutes. Here are the steps you need to follow:

Step One: Disconnect the Negative Battery Cable

The first thing you need to do is disconnect the negative battery cable. This will prevent any electrical shorts from occurring when you’re working on the Throttle Position Sensor.

Step Two: Remove the Air Intake Duct

The next step is to remove the air intake duct. This will give you better access to the throttle body and sensor. To remove the duct, simply loosen the clamps and pull it off.

Step Three: Remove the Throttle Position Sensor

Once you have access to the throttle body, you can remove the Throttle Position Sensor. To do this, simply unscrew the sensor and pull it out.

Step Four: Install the New Throttle Position Sensor

The last step is to install the new Throttle Position Sensor. To do this, simply screw in the new sensor and reconnect the negative battery cable.

Frequently Asked Questions

Do You Have to Reset the Computer After Replacing the Throttle Position Sensor?

No, you don’t have to reset the computer after replacing the Throttle Position Sensor. Although, it’s always a good idea to drive the vehicle for a few miles to see if the check engine light comes back on.

Can You Clean a Throttle Position Sensor?

Yes, you can clean a Throttle Position Sensor. However, it’s usually not necessary because most sensors come with a built-in filter. The filter prevents debris and dirt from clogging the sensor.

How Much Does It Cost to Replace a Throttle Position Sensor on a Dodge Ram?

The cost of replacing a Throttle Position Sensor will vary depending on the make and model of your vehicle. However, for most Dodge Rams, the cost will be between $200 and $300.

How Often Should You Replace a Throttle Position Sensor?

Most Throttle Position Sensors will last for the lifetime of the vehicle. However, if your sensor is damaged or malfunctioning, it’s best to replace it as soon as possible.

Can I Calibrate My Electronic Throttle Body?

There’s no need to calibrate your electronic throttle body. The computer will automatically adjust the idle speed when you install a new Throttle Position Sensor. Calibrating the throttle body is only necessary if you’re having problems with idle speed.

What Causes a Throttle Position Sensor to Go Bad?

There are a few things that can cause a Throttle Position Sensor to go bad. The most common cause is contamination from dirt and debris. This can happen if the filter on the sensor becomes clogged.

Another common cause is electrical issues. This can happen if the sensor is exposed to water or if there’s a problem with the wiring.

Lastly, physical damage can also cause the Throttle Position Sensor to go bad. This can happen if the sensor is hit by something or if it becomes damaged during installation.

What Voltage Should a TPS Read at Idle?

The voltage should be between 0.45 volts and 0.55 volts at idle. If the voltage is outside of this range, it’s a good idea to replace the sensor.

What Does a Bad Throttle Position Sensor Sound Like?

A bad Throttle Position Sensor can cause your vehicle to run rough at idle. You might also notice that your vehicle stalls or hesitates when you’re accelerating.

Conclusion

Resetting the Dodge Ram throttle position sensor is a simple task. Start the engine without turning it on. This is accomplished by moving the key to the “On”. After that, depress the accelerator pedal until it touches the floor.

Continue to hold down the pedal for 30 seconds after this time has elapsed. Turn off the automobile and wait a few minutes before restarting it and your TPS will be reset.

You should watch out for the various symptoms of a bad sensor such as the vehicle running roughly at idle or it hesitating and stalling when you try to accelerate. If you notice any of these, then it’s time for a new sensor.

Replacing the TPS is easy and can be done in about an hour with just some basic tools. Be sure to follow the steps above and you’ll have your truck running like new in no time.
