· The Electronic Throttle Control (ETC) system uses two Accelerator Pedal Position (APP) Sensors to monitor the accelerator pedal position. The APP Sensors 1 and 2 are integrated into one assembly located at the pedal assembly. Each sensor has a 5volt reference circuit, a low reference circuit, and a signal circuit.

A throttle position sensor is similar to the motor cortex in the human brain, it controls one of the most important components of the car that keeps your engine running like a throttle body. Picture a little module in the car that reads how far down you have pressed the gas pedal.
This feature is dependent on the throttle valve. When you press down on the gas pedal, your throttle body unit''s valve opens. This causes your throttle position sensor to adjust the engine intake manifold accordingly. This little sensor is essential to a correct mixture of air and fuel.
· This can often be a faulty sensor, faulty valve, low transmission fluid level, or a bad shift solenoid. 4. ... Showing codes P2100 and P0220. One code relates to the throttle position sensor and the other to the accelerator pedal. I have removed the pedal and tested. ... The cars keeps going into limp mode.
· O2 Sensors. Your SRX’s oxygen sensors measure the amount of oxygen in the exhaust to help insure that the proper air/fuel mixture is realized. If they totally go bad they usually don’t trigger the reduced engine power mode, but if you plug your code scanner and it comes up with an oxygen sensor related code such as P0160, it’s definitely ...
· Not only will a faulty throttle position sensor cause problems as you attempt to accelerate, but it can also give you trouble as the car idles. Even though you are not pressing the gas pedal at idle, the sensor may still be delivering inaccurate data. If the sensor is malfunctioning bad enough, your car may not even stay running at all.
· |P2138 CADILLAC code description The Accelerator Pedal Position (APP) sensor is made up of 2 sensors that are housed inside one assembly. The Engine Control Module (ECM) supplies a separate 5volt reference circuit and a low reference circuit for each of the sensors.
These operations are affected when a bad throttle position sensor feeds erroneous data to the car’s computer. Because of this, the following can occur: 1. Difficulty while changing gears. 2. The fuel economy of the car drops drastically. 3. Causes difficulty in setting base ignition timing of …
The gas pedal is electric , has sensors the PCM uses so it knows how much to open the throttle blade . Electric DC motor on the throttle body to open an close the throttle blade . Video''s on youtube that show how it works . Could have bad sensors at the gas pedal or throttle position sensors on the throttle body .
· P0121 – Throttle position (TP) sensor A/accelerator pedal position (APP) sensor / switch A range/performance problem. By Mia Last Updated 20160603 ASE Master Tech
The accelerator position sensor is made up of two individual sensors, with both sensors designed to have individual sensor return wiring. Each sensor has a varying voltage range. The PCM system receives and processes the electrical signals from the ACC sensors, along with signals from the direct current (DC) motor, which sets the throttle plate through a throttle cable.
· The accelerator pedal position sensor is defective. Lastly, there''s a fault in a circuit of the throttle position sensor circuit or the accelerator pedal position sensor circuit. This fault could be an open short, corroded wiring, or poor connection. Don''t throw parts at your car.
The throttle position sensor is one of the most crucial components of any fuel injection system, right after the computer and fuel injectors in terms of importance. GM Sensors have traditionally been outsourced to overseas manufacturers, the same ones who supply throttle position sensors to other makes like Ford and ...
· During adjustable pedal system operation the difference between brake and accelerator position sensor inputs to the memory seat module must not exceed 31 counts. Any time adjustable pedal system components are replaced, such as a memory seat module or pedal position sensors, the system must be calibrated.
· A failing accelerator pedal sensor’s impact is pretty much obvious as it directly affects how the car drives and responds to the pedal and gas …
· The throttle position sensor can fail in several ways, all of which result in poor fuel economy at best, and performance limitations that may create a safety hazard for you and other motorists at worst. It can also cause problems when changing gears, or setting base ignition timing. This sensor can fail gradually, or all at once.
