DKT Interface
The throttle angle and the engine temperature are transferred via the Throttle Valve (DKT) interface. This involves a pulse width-modulated signal (square wave voltage with fixed frequency and variable duty factor).
At terminal 15 "ON", the Digital Motor Electronic (DME) control unit transmits the engine temperature and the throttle angle half a second after detecting an engine speed greater than 500 rpm.
Faults on this line are detected by the Electronic Transmission Control (EGS) control unit.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
