My topic is the KE-Jetronic injection system which I try to demystify as much as I can. For all of you to understand the system in brief - Developed in 1973 and being mounted into cars up to 1993 as it went in history. But why these to letters!?(KE) K(from German "kontinuierlich" meaning continuos, without interruption) the MECHANICAL injection system on which the fuel starts flowing from the fuel tank sucked by the FUEL PUMP and delivered to the FUEL DISTRIBUTOR which sends fuel to the INJECTORS while the majority of it flows through the FUEL PRESSURE REGULATOR through its return line back to the fuel tank again. The letter E(electronic) has to mark the electronic sensors (the developement starting from early eighties) which had to inform the ECU about the current state of the engine so that the ECU(Electronic Control Unit) then could create current signal in mAmp(miliampers) and send it to four crucial components for the system - the EHA(the electro-hydraulic actuator,a unit consisting of a magnet, an electromagnet and a baffle plate) which had to fine tune the engine in each of its phases, the ICV(the idle control valve), the unit which was predicted for the engines perfect idle, the X11(the diagnostic socket) where the duty cycle(the ideal mixture) was adjusted and the X11/4(the code reader) - the socket which from any codes were read if present using an OBD1 scanner. An extraordinary injection system which could be fully repaired in your own garage using a multimeter and a pressure gauge only for its fine tuning, together with some common tools.

This tutorial video will help you save a lot of money and it's something everyone can do at home. This video explains the procedure how to replace and calibrate the A/F sensor potentiometer, it's the same procedure for every W124 engine type up to 1993 and where to buy a good and cheap one. For any further questions on how to know if you need to replace it or not, leave a comment below. The link to the potentiometer: https://www.ebay.com/itm/Drosselklappensensor-MB-Mercedes-Benz-03437224015-03437010039-03437224035/133173658800 The goal of my videos is to teach people how to diagnose and repair their issues without paying money for the work and for the part in the repair shops - the spare part they have to buy and it's up to them whether they are going to buy used or new one, a branded or unbranded one. That's why I provide people with reference numbers of all the parts so that people can use them to buy the parts themselves and not for someone to earn money on them.
