So as you can see there is some angular movement angular adjustment of that TPS unit and with the throttle at the idle.
Does a new throttle position sensor need to be calibrated?
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. First, be sure you have correctly wired, and assigned the throttle sensor signal input to "TPS Raw" in the Analog Settings.
What happens if TPS is not calibrated?
If your TPS is faulty or uncalibrated, the sensor will be unable to accurately determine the position of the sensor. This will lead to a variety of symptoms, all of which are caused by the fact that the ECM is delivering the wrong air/fuel ratio to the cylinders thanks to the bad sensor.
How do I relearn my throttle position sensor?

How do I reset my idle speed?
You can reset the idle air control (IAC) valve by turning the car on, putting the car into park, pressing the brake down, then pushing the gas pedal down, counting down about 5 seconds, turning the car off, waiting 10 seconds and start the car again, checking to see if the car is idling properly.
How do you fix high idle after cleaning throttle body?
Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel. The idle will relearn if you put the vehicle in drive and allow the idle to come down with all accessories off for about two to three minutes.
How do you program a throttle body?

Introduction
The throttle valve cable, or TV cable, connects between the throttle assembly on the engine and the transmission. The TV cable communicates the position of the throttle to the transmission hydraulics and governor assembly. This is used to scale shift points and control shift firmness.
Calibration Procedure
Put SAFETY FIRST. You should not attempt the throttle sensor calibration unless you are thoroughly familiar working around engines.
Diagnosing Problems with TPS Calibration
Here a few common calibration problems and recommendations on how to solve them.
Calibrating the Throttle Position Sensor
Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE.
Throttle Calibration Wizard
You can use the Throttle Calibration Wizard (under ECU Tools menu) to easily calibrate your throttle. It will also automatically correct the calibration for throttles wired "backwards". (Where the voltage decreases as throttle opening increases.)
Traditional HRT Calibration Method
You can also choose to calibrate the throttle sensor using the HRT Table for the TPS Sensor. You can access it from Entity Tree View>HRTs>TPS HRT.
How does a throttle position sensor work?
The engine computer uses the throttle position sensor to read 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 your air/fuel ratio to become inaccurate, which is accompanied with poor throttle response.
How to remove Torx throttle position sensor?
Step 1 – Remove the throttle position sensor from the throttle body. First, disconnect the electric connector from the sensor. You will need to squeeze the bottom side of the connector while pulling it away from the sensor to make it release. There are two Torx head screws holding the sensor to the throttle body.
What year did Dodge Rams use throttle control?
Dodge developed a calibration procedure for the throttle position sensor that may restore proper operation to your Ram. After the 2003 model year, Dodge Rams with the 5.7 Hemi engine began using "drive-by-wire" electronic throttle control. This article does not apply to those trucks.
How to clean a sensor?
Using CRC (Electronic Component Cleaner) or equivalent, clean the sensor by spraying the cleaner into the drilled hole. As you spray, rotate the sensor shaft (pink circular component) to ensure the electrical contacts has been reached. Dry the sensor by using compressed air in a light pressure, or let it air dry.
How many volts does a Honda Civic have?
The engine computer supplies the sensor with a steady reference voltage of five volts through one wire, and receives a signal from 0.5 volts (closed throttle) to 4.5 volts (open throttle) from the potentiometer as the throttle is moved.
