Do you have to relearn a throttle position sensor?
Resetting is sometimes all that is required to restore your sensor. Code errors can cause your throttle position sensor to work erratically or incorrectly. Otherwise, you'll need professional software to reprogram your sensor. This job is best done by a professional mechanic.

Do you have to reset computer after replacing throttle position sensor?
After replacing the throttle body to your engine, if the engine light was on and has a pending code, the code will go away. If the code was a hard permanent code, then the ECM (computer) would need a hard reset.
What happens if you don't relearn your throttle body?
What happens when you replace the throttle body? If you replace the throttle body, the PCM won't know and will continue to use the adaptive settings as if the carbon buildup is still in place. If you don't do a relearn procedure, the PCM will “hunt” for a new baseline idle.
Do you need to calibrate a new throttle position sensor?
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.
How do I reset my throttle body?
Leave the key off for a moment, turn the key to the "On" position again, wait 3 seconds, and press the accelerator 5 times in 5 seconds. Wait 7 seconds, and hold the accelerator down. The check engine light should start blinking, continue to hold pedal down until it stops blinking. You can then start the car.

How do I reset my electronic throttle control manually?
Resetting your electronic throttle control manually can be a tricky job. First, make sure the accelerator pedal is fully released. Next, turn the ignition on and then turn it off and wait for ten seconds. During these ten seconds, be sure the throttle valve is moving by listening for a sound of operation.
What does an idle relearn fix?
In the event you are experiencing an erratic idle after loading a tune or after performing any action that clears KAM (Keep Alive Memory), an Idle Relearn can help you get back on track. The KAM or “Keep Alive Memory” is the memory that is stored in the powertrain control module (PCM).
Accelerator Pedal Position Sensor
The accelerator pedal position (APP) sensor allows smooth acceleration while utilizing minimal energy. The APP sensor on the ‘electronic throttle control system with intelligence’ (ETCSi) detects the pedal position. The AAP sensor also converts pedal movement into an electronic signal that opens or closes the throttle body.
Throttle Position Sensor
The APP and TPS sensors have the same electrical circuitry. This sensor, like the APP sensor, is located on the throttle body and translates the throttle body butterfly valve angle into a voltage signal for the PCM. The TPS monitors whether the throttle valve or blade is open, which is indicated by how far the accelerator pedal is pressed.
Is there a difference between a throttle position sensor and a pedal position sensor?
Both the APP and TPS sensors have the same electrical architecture. The TPS sensor unit is located on the throttle body, same like the APP sensor, and translates the throttle body butterfly valve angle position into a voltage signal that is sent to the PCM unit.
Is it possible to drive without TPS?
The TPS, or Throttle Position Sensor, informs the ECU about how wide the throttle is opened and consequently how much gasoline is required. Without a TPS, you will be able to drive, but not very efficiently. When you open the throttle, the ECU detects a lean situation in the o2 and attempts to richen it up.
Symptoms of a faulty or failed throttle position sensor include
1. Car won’t accelerate, doesn’t have enough power to accelerate, or accelerates by itself It may appear that the vehicle is not accelerating as quickly as it should. It has a nice acceleration but lacks power. On the other hand, even if you haven’t hit the accelerator, your automobile may abruptly accelerate while you’re driving.
How do I go about relearning the throttle body?
Some vehicles may require a throttle/idle relearn after the throttle body has been cleaned. Throttle retraining can also be accomplished without the use of a scan tool, by just allowing the vehicle to idle in park for several minutes while the ECM learns.
Sensor for throttle position and Accelerator Position Sensor
TPS and APS are sensors that monitor an engine’s air intake. The sensor is commonly mounted on the butterfly spindle/shaft, allowing it to monitor the throttle position directly.
What happens if you replace throttle body?
If you replace the throttle body, the PCM won’t know and will continue to use the adaptive settings as if the carbon buildup is still in place. If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle.
What is a fly by wire throttle body?
Many car makers including GM started installing fly by wire electronic throttle bodies. In those vehicles, the “gas” pedal isn’t connected to the throttle body by a cable. The pedal simply provides an electronic signal, telling the throttle body how much acceleration you’re requesting.
How to Reset Throttle Position Sensor
If you’ve properly identified the throttle position sensor as the cause of problems in your Toyota, then follow these steps on how to reset it. However, if you’re uncertain, take a look at the sections explaining how the throttle position sensor works, and what the common signs of failure are.
How Does the Throttle Position Sensor Work?
Throttle position sensor, or TPS for short, is an important part of the fuel management system and directly links the gas pedal and the engine. As the driver applies pressure on the gas pedal, TPS converts that information into valve movement, dictating the amount of air flowing into the engine’s intake manifold.
Signs of Failure
The first warning sign comes before any symptoms, in the form of the check engine light. If you’re driving a Toyota with more than a few years of service, chances are that the check engine light is already lit up for some other, potentially insignificant reason.
Conclusion
Resetting the throttle position sensor is a very simple process, so it’s worth trying out these methods before going to a mechanic’s. Idling issues should disappear easily, but if you’re facing unresponsive throttle and inconsistent performance, your throttle position sensor might need a replacement.
