Hi I met exact the same issue - 2001 mercedes ML320, also replaced pedal accelerator sensor which did not work. Looking for guidance please!

i have the same problem with my ml320 2001. need help

it seems that it is related with sudden brakings.

My 2001 ml320. Sudden and high to low speed braking always cause the same problem. Solution??? Thanks dan

Hey Guys, Alright so after 2 years of dealing with this overwhelmingly frustrating intermittent acceleration issue, my mechanic finally pin pointed the problem. It was a faulty Throttle Body. I believe this has to do with fuel injection. Ultimately he told me oil got into the throttle body which was causing the problem. Before my mechanic switched out the throttle body, he had to change out my entire pedal assembly because he pulled a fault code. The reality with this problem is there may be more than one culprit causing the issue and in my case that is what happened. Changing only the sensors will not work. You have to completely switch out these parts. DO NOT BUY USED PARTS BUY THEM BRAND NEW OEM BOSCH! This is not a one day fix and I would recommend taking your car to a knowledgable mechanic to deal with this issue as this is not something you should try to fix yourself.Trust me we tried. Also note that when I was experiencing this problem my check engine light NEVER came on. It should have but it didn't and that's probably because of the faulty sensors. After the throttle body was switched out the check engine light still did not come on. HOWEVER after the fact, I drove about 2 drive cycles and my check engine light finally came on and pulled 3 codes. I am mentioning this because you too may experience this. The 3 codes I pulled were: P0410 PO170 PO173 You can find the Throttle body assembly on Partsgeek.com for about $305 AND you can qualify for $15 off since the cost is over $300. The code for the $15 off is: (SAVE15) Below is the direct link for everyone's convenience: http://www.partsgeek.com/ss/?i=1&ssq=0280750019&x=0&y=0 Hope this helps!! Happy Holidays everyone!

Hello Sofia! I would like to check to see if you are still having issues with acceleration or not? Just want to see if changing the throttle body did indeed repair your issue?

hi sir

i can,t andastand what is this problem start car no acceleratur i have check com CODE P0507 THIS CODE idle speed control impausible .THIS CODE C1022 FAULT in can communication with me N3/10 I have accerelarur padel sensor change throttle body change but no problem solve ,i can,t andastand,please help me

It's ur yaw sensor. I replaced mine $1300 no problem since. I have a Slk 320 2002. My nephew a master mechanic for mercedes. I kept losing power and engine was still on, it scared me happened 2o times. Called nephew in another state he diagnosed over phone. Mb dealer mechanic pulled codes and agreed. No problem since. Have it checked out.

When a Mercedes Benz throttle body has been changed it needs to be reset.Within the (ME) motor eletronics ( learning full open and closed throttle positions) If codes remain as in c1022 CAN fault / no comm with (ME) the process will not be completed until fault is resolved.The (CAN ) controller area network is were the data is transfered. If one of many componets on the network is having a CAN problems the data to relearn throttle may not be possiable. Mbtech.

any body check there transmission plug to see if its wet , then trans computer ??

Muhammed get your your a Code tester reader and erase the ecu cpu by plugiging in the Scan tool into your OBD2 connector .. once it has reset clearing out all data then oit should pick up the new sensor as the only sensor to running in it ..

BAS issue is check your tail lights and break switch .. and break light bulb connectors .. as they corrode and get weak signal .. due to this problem causes the BAS light to come on .. if not find there then check one of your whell speed sensor wires or the sensor can as well be bad ... but it is not a big cost to fix.. very cheap fix .

or yes correct next is YAW sensor located inside your sift console little small box about 1inch by 1 inch ... or 2 inch not very big at at ... plastic crap box sensor ... but that YAW sensor you can get cheap as well on ebay...

>>>>>YAW Sensor- is cheap around about $40.00 to less then a $100.00 <<<<<< /// not no $1600.00 anyone tell you take to a mechanic shop is crazy.. this sensor like i sayed is located inside the shifter console ... down inside the console you will see it in front of where the shifter cable connector is at .. two little 10mm bolts hold that little crap plastic box and a electrical plug in connector ... is to replace ...
