[2] When a vehicle detects a problem, it generates a DTC code which is a unique code that corresponds to the specific problem ...
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).

All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
A range of rugged hand-held scan tools is available. Simple fault code readers/reset tools are mostly aimed at the consumer level. Professional hand-held scan tools may possess more advanced functions Access more advanced diagnostics; Set manufacturer- or vehicle-specific ECU parameters; Access and control other control units, such as air bag ...
Early cars had a hand lever to control the throttle, either directly, or by controlling an engine speed governor which in turn controlled both the throttle and timing. [6] In 1900 the Wilson-Pilcher car was introduced in Britain which had a hand controlled speed governor, and a foot throttle which could override the action of the governor.
A throttle position sensor (TPS) is a sensor used to monitor the throttle body valve position for the ECU of an engine. The sensor is usually located on the butterfly spindle/shaft, so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used.
1991 was the final year for the eleventh-generation Eldorado. New this year was Cadillac's 4.9 liter port fuel injection V-8 engine with GM's 4T60-E electronically-controlled four-speed transmission. The Cadillac-exclusive "viscous converter clutch" provided smoother shifting under hard acceleration.
