Gsab Posted April 20, 2020 Report Share Posted April 20, 2020 Mercedes W202/w210 .DBW pedal sensor with cable Does any one have the details for the plug connection for this type of sensor please. I have seen it somewhere, have searched on the forum but have come up empty. Thanks, ] Edit to add: Found what I was looking for-posting here for Forums members .

Gsab Posted August 23, 2020 Author Report Share Posted August 23, 2020 Need some help here please. I just can`t get around the hall setup here. Firstly, does this type of sensor only have one 5v in, which in this case would be USP1 (pin 1)-silly question but I need direction here. Is pin 4 not connected or is it "part" of pin 1 and so also needing a 5v in ? The diagram shows a common 5V in-supply. Measuring the sensor I have a true TPS resistive half but the other part does not measure the same as the first. Second issue I`m having is the 2.5v output .Do I simply set up the An V in to a range of 0 to 2.5 V ? How would the ECU interpret this vs 2 varying 5 V values ? Do I simply leave the input as a - to 5v in ? Quote Link to comment Share on other sites More sharing options...

The drawing is incorrect or not clear since it shows 6 pin numbers but only 5 pins. Since all other pin numbers are to the left of the pin I would say the most likely interpretation would be Pin 4 is SP2S and pin 2 is the one with no connection. 8 hours ago, Gsab said: Second issue I`m having is the 2.5v output .Do I simply set up the An V in to a range of 0 to 2.5 V ?

You dont need to enter any voltages, just hit the AP calibration and follow the instructions on screen. Quote Link to comment Share on other sites More sharing options...
Gsab Posted August 24, 2020 Author Report Share Posted August 24, 2020 Ah, yes, I see what you are saying about the pin numbering. Thanks Adam, busy wiring and will feedback here. Thank you. Quote Link to comment Share on other sites More sharing options...
Gsab Posted September 29, 2020 Author Report Share Posted September 29, 2020 For those planning on using the Mercedes AP module, PIN2 also needs 5v in. Quote Link to comment Share on other sites More sharing options...
Gsab Posted September 29, 2020 Author Report Share Posted September 29, 2020 Started my install as you can see by the naming of it in April. Got the above Mercedes AP module working great, calibrated, I used Adams generic settings as per the new Layout files he so graciously supplied.(Thanks for those) Throttle wired in, calibrates, and then it sits and buzzes. Cannot get the AP to activate the t/b at all. Not in on mode nor in setup made. Switch dbw off and manually activate the throttle body blade and the Tps voltages work as expected. Relay wired in as required, working as intended. 2 days of checking why sure makes that cable t/b look attractive ! :-) I have attached the PCL file that I am using, please note the the relay has been moved from AUX 16 to AUX 8 and worked as intended. Any help as to why the t/b will not activate would be most welcome. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted September 29, 2020 Report Share Posted September 29, 2020 Could you attach a log of everything powered up with accelerator pedal being moved please Actually one quick note is that you have it set to Quiet throttle when stalled so if you are testing with the engine off the throttle won't move. You also have an ethrottle fault recorded so not a bad idea to clear your fault codes and see if that returns. Quote Link to comment Share on other sites More sharing options...
Gsab Posted September 30, 2020 Author Report Share Posted September 30, 2020 Hi Vaughn, thanks for the response. As requested, Logfile. Changes made as per your suggestion. Please note that I have changes e-throttle relay form a high to a low activation as well. Wired in changes. As mentioned, AP and T/B calibrate perfectly, 500hz buzzing heard from t/b. Switching e-throttle off and manually deflecting the plate, reads t/p high and low as required. Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 30, 2020 Report Share Posted September 30, 2020 In your log your E-throttle target shows 8.7% all the time. 3.2% is coming from the idle base position and 5.5% from the E-throttle target table. So it appears there is something wrong with your E-throttle target table, you have an axis set up wrong or something. Can you attach the map as it is now - as it seems it is different than the one you attached above. Quote Link to comment Share on other sites More sharing options...
Gsab Posted September 30, 2020 Author Report Share Posted September 30, 2020 Your deduction is spot on Adam, I have just changed the Target table to table # 3 and it all works perfectly. I have not yet looked at the contents of table # 3. Target table 1 and 2 do not work. I am attaching both my pcl and log file. Learning long and hard here..... Thank you.

Adamw Posted September 30, 2020 Report Share Posted September 30, 2020 I suspect there is not something initialised correctly in the background for table one. Sometimes this can happen when you first set something up and you choose "no" when you get the message "do you want to clear the * table and set the axis to default values". So try turning E-throttle mode to off, then back to set up mode, it should ask you again if you want to clear table 1, choose yes. Then I suggest if you dont want the X axis like your old set-up, then go into axis set-up and set it to none. Quote Link to comment Share on other sites More sharing options...
Gsab Posted October 1, 2020 Author Report Share Posted October 1, 2020 Aah, I shall do so. Thank you. Edit: Bingo !! All good. Thanks Adam/Vaughan. Vaughan 1 Quote Link to comment Share on other sites More sharing options...
