The engine computer system uses the throttle place sensor to check out the position of the throttle plate while it"s being moved by your foot via a cable. An electrical glitch in the sensor can relay false readings to the computer and cause her air/fuel ratio to come to be inaccurate, which is accompanied with bad throttle response.

This article uses to the evade Ram third Generation (2002-2008).

The throttle place sensor is placed on the side of the engine accelerator body. It has actually a three-wire potentiometer, an interpretation it different its resistance based ~ above its position. The engine computer supplies the sensor through a steady referral voltage of five volts with one wire, and receives a signal indigenous 0.5 volts (closed throttle) to 4.5 volts (open throttle) from the potentiometer as the accelerator is moved. The electric contacts inside are susceptible to dirt, heat, and also vibration. Over time, carbon buildup ~ above the contacts will result in high resistance in the circuit, producing drivability problems. Damages to the sensor or the associated wiring deserve to be felt as engine hesitation, stumbling, and even misfires. Dodge occurred a calibration procedure for the throttle place sensor that may restore proper operation to her Ram.

After the 2003 design year, dodge Rams with the 5.7 hem engine began using "drive-by-wire" electronic throttle control. This write-up does not use to those trucks.

Option 1 – Re-calibrating the sensor

Step 1 – Re-calibrate sensor

Before replacing the sensor, try the calibration procedure:

Insert vital into the ignition and also turn the crucial to the "on" (not start) position.Wait for every one of the warning lights to go out. The inspect engine light may remain on.Slowly boring the accelerator pedal all the means to the floor.Slowly relax the accelerator pedal till it"s all the method back up.Turn the ignition an essential to "off".Start the engine.

You can additionally find this procedure in her Ram"s organization manual.

If the calibration walk not aid you, you can try cleaning or instead of the sensor.

Option 2 – cleaning or replacing

Step 1 – remove the throttle place sensor indigenous the throttle body

First, disconnect the electric connector native the sensor. Girlfriend will must squeeze the bottom side of the connector when pulling it far from the sensor to do it release.

There space two Torx head screws hold the sensor to the throttle body. Carefully pull the sensor out of the accelerator body once these screws space removed.

Figure 2. Once the connector is removed, the Torx screws are straightforward to reach.
Pro Tip

Many device manufacturers do mini ratchets that have the right to be purchased with Torx bits to do this process easier.


Step 2 – Drill a small hole right into the sensor

Using a 1/8" drill bit, make a tiny hole ~ above the inner next of the sensor. This is best made at the facility of the angled surface. Usage light push while drilling, or girlfriend will hazard damaging the sensor.

Using CRC (Electronic component Cleaner) or equivalent, clean the sensor by spraying the cleaner right into the drilled hole. Together you spray, rotate the sensor tower (pink circular component) come ensure the electrical contacts has actually been reached. Dry the sensor by using compressed air in a irradiate pressure, or let it air dry.

Once the sensor has dried, cover the hole through a tiny piece of electrical tape. Coat the external of the electrical tape face as well as edges v clear RTV silicone come ensure a water and also dirt chop seal.

Re-install the sensor onto the throttle body and tighten down the 2 Torx screws. These screws perform not require lot torque. Then re-connect the electrical connector. You may want to retry the calibration procedure once this is finish (Option 1).

If you space installing a brand-new sensor instead, your sensor may come v a brand-new gasket or O-ring certain to your model year.
