The driver may not react quickly enough, so the computer backs off the throttle to regain traction and reduce wheel spin or skidding. Throttle body units are quite expensive (OEM units typically cost $700 or more), so accurate diagnosis is essential to prevent unnecessary parts replacement and warranty returns. Electronic throttle control (ETC) is an automobile technology which electronically "connects" the accelerator pedal to the throttle, replacing a mechanical linkage.

Generic OBD II trouble codes for possible pedal position sensor faults include P0120 through P0124, P0220 through P0229, plus any OEM enhanced P1 or P2 series codes for that specific vehicle. It will operate Jenvey individual throttle body systems as well as other applications. 5.0 out of 5 stars 7. For the best experience on our site, be sure to turn on Javascript in your browser. When the fault has been identified, the faulty part can then be replaced. Electronic throttle control facilitates the integration of features such as cruise control, traction control, stability control, and precrash systems and others that require torque management, since the throttle can be moved irrespective of the position of the driver's accelerator pedal. * The accelerator pedal position (APP) sensor in a Ford Mustang has three sensors and a total of 7 circuits:

The Throttle-By-Wire system also monitors the throttle position sensors on the throttle body. All cars having a TPS have what is known as a 'limp-home-mode'. A series of investigations by the U.S. National Highway Traffic Safety Administration (NHTSA) were unable to get to the bottom of all of the reported incidents of unintended acceleration in 2002 and later model year Toyota and Lexus vehicles. All major components, except for the electric motor, have been designed, developed and manufactured by AT Power.

ACDelco 12679524 GM Original Equipment Fuel Injection Throttle Body with Throttle Actuator In 1997, Chevrolet opted for "Throttle Actuator Control" (TAC) on its C5 Corvette.

The Electronic Throttle Control system within most vehicles is constructed with three important parts: the accelerator pedal, the throttle valve, and a control module or PCM . Note: It is NOT possible to convert an electronic throttle back to an ordinary mechanical throttle linkage. It is these two signals that are used by the ECM to calculate the mean voltage used to establish ultimate throttle position. To provide better service to you on our websites, we and our service providers use cookies to collect your personal data when you browse. [1] A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM). But just opening or closing the throttle valve by sending a new signal to the electric motor is an open loop condition and leads to inaccurate control. Generic OBD II codes for this kind of problem include P0638 & P0639, plus any OEM enhanced P1 or P2 series codes for that specific vehicle. A study has been conducted on a mass production on-road sport motorcycle in order to prove feasibility of an ETC system.

Simplify installation and increase operator safety and productivity, combined with space-saving design and electromechanical interface, allows engine speed controls to be placed in ergonomic positions. Today, that mechanical linkage has gone the way of the dodo in favor of electronic throttle control. But on others it requires a scan tool or special manual procedure. It will operate Jenvey individual throttle systems as well as other applications requiring fast and accurate response within its operating range. Instead, the position of the throttle valve (i.e., the amount of air in the engine) is fully controlled by the ETC software via the electric motor. The engine control computer shuts down the signal to the throttle position motor and a set of springs in the throttle set it to a fast idle, fast enough to get the transmission in gear but not so fast that driving may be dangerous.

If you put the pedal to the metal on a car with Throttle-By-Wire, you won't impress anybody by smoking the tires. A code reader or scan tool is required for diagnostics.

* TP2 voltage with positive voltage slope (0-5 volts). The codes can then be cleared, and hopefully everything will work correctly again. In a 2005 Mustang, three sensors are used. They should mirror each other. * 2 reference voltage circuits (5 volts). * 2 signal return (ground) circuits.

On some vehicles this occurs automatically every time the key is turned on. The pedal position sensor may be part of the pedal assembly, or a separate component mounted at the top of the pedal. * On a Ford Mustang, the TPS sensor has 4 circuits: [4], Discussion of this nomination can be found on the. [2] The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerator pedal position sensors, engine speed sensor, vehicle speed sensor, and cruise control switches. The throttle position sensors, however, can usually be replaced separately. It will operate Jenvey individual throttle body systems as well as other applications. The Jenvey ETA2 Motorsport electronic throttle actuator has been created specifically for use with motorsport and high-performance engines. The software then converts these degrees to counts, which is then used to command throttle position. [citation needed] Nowadays, the vast majority of drivers have no idea how much intervention is happening. APDTY 16119-AE01C Electronic Throttle Body Assembly w/Actuator IAC Idle Air Control TPS Positio… * APP3 voltage with positive voltage slope (0-5 volts). Electronic throttle control also provides some warranty advantages for the vehicle manufacturer, too, by limiting "abusive driving" by lead-footed motorists. * 5-volt reference voltage. * The use of a DSO is very valuable when diagnosing electronic throttle control problems. 82.

On some systems, a special relearn procedure is required when parts have been replaced or the throttle control wiring harness has been disconnected. FREE Shipping by Amazon.

Skip to the beginning of the images gallery. Much of the engineering involved with drive-by-wire technologies including ETC deals with failure and fault management. The throttle control system will remain in the limp-in mode until the fault can be diagnosed and repaired.

It won't happen -- unless there is an over-ride switch to deactivate traction control. For the best experience on our site, be sure to turn on Javascript in your browser.

ETC provides some benefit in areas such as air-fuel ratio control, exhaust emissions and fuel consumption reduction, and also works in concert with other technologies such as gasoline direct injection. As soon as your throttle actuator reaches its recommended service life, replace it. This relationship will show if the system is working properly or if there are problems in the feedback or control circuits.
