In this video I will be talking about some minor disagreements on the way a potentiometer is measured. The goal of this video is to teach you to check your potentiometer each 90k miles. If you get 4 impulses out of your ECU, then it's a clear sign that your potentiometer is bad and if you want to check it this is how it's done. Talking about the potentiometer from Germany.

What am I talking about?
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.
"Happy Mercedesing"

Hello, great video, just quick note for all of you (if you remove potentiometer from a car then test 1&3 pins IF ITS STILL IN CAR (NOT REMOVED) then test 1&2 pins - it's showing ohms as it written in service manual. Please read carefully in service manual there is not mentioned to remove it before testing, just unplug connector and check, hope it helps to get your nominal values ;)

Yes, that's what I mentioned in the video also. Always test the potentiometer with the potentiometer on the airflow meter.

Hi, Thank you for your videos, they are great help. I did bench test on my potentiometer, and I get 4.9 between 1 & 3 , and zero between 1 &2. Is this unit good? Also, which brand do you recommend that we have a better chance to adjust it.
@mercedeske
@mercedeske 2 жыл бұрын
Hi, and thanks for your kind words. The answer to your question - no, it's not good. If you don't get a linear increase in resistance when you deflect the sensor plate while measuring on the pins 1&2 and you get sudden jumps in resistance, then it's a clear sign that you have to replace the potentiometer. It has to be replaced anyway after 90k miles(150k km). You can buy any of those from Germany or Netherlands(you have them on ebay) if the original one is too expensive for you. I bought one from the guy from Germany and I am very happy with the results.

The idle of the vehicle does not change when I remove the Lmm. Do I absolutely have to buy this? I disassemble the idle valf and clean it and it works, but at idle it runs at idle relative to the adjusting wheel of the idle engine.
@mercedeske
@mercedeske 3 жыл бұрын
If your vehicle doesn't stall after cold start, if the engine doesn't have rough idle, when you downshift and your vehicle doesn't stall at low RPM then it's okay, that means that your LMM is okay. You can always check it on the diagnostics. Perform the impulse test, if you don't get 4 impulses, then your LMM is okay.

As for the potentiometer, yes it refers to the M104, too. The point of the video is to show that there must not be "bouncy" resistance. There... so, Happy Mercedesing 😊 😃

I know this is an older video, but maybe you can answer my question. There is a small adjusting screw, 2, maybe 3mm in diameter, set down in a depression, to the driver's side of the potentiometer. What is that adjustment screw used for?
@mercedeske
@mercedeske Жыл бұрын
The signal of the potentiometer is being adjusted there. That's something I don't want to mess with and something I still don't know how to "manipulate with". The seller just told me not to touch it and either to leave it there or to fill it up with something.

@@mercedeske Well, I used to work in control electronics at one time, so I just had to know. I had a new, aftermarket potentiometer on the bench and tested it. That little screw is there to "Trim" the pot. So back to the small screw on the car. After I tightened down my pot, with the ignition on, and engine off, I got 0.80 VDC. across the center and top pins. Turning the small screw CCW, I was able to get the voltage down to 0.72 VDC and figured that was good enough for now. Engine fluctuations due to Lamda are at a minimum after the cold cycle ends, The engine runs fantastically, it pulled 90 mph without a hiccup. I'm a happy camper. ;)
