CEL bunch of codes help please
Hey guys
I have a 2001 c240. Its been a great car this far but my CEL light just came on ,and sadly theres 4 different codes to come with it. ,This is my first MB. Ive had VW's all my life. So cut me some slack. Im just starting my research on what this could be. Any help would be appreciated.
If the CEL didnt come on I probably wouldnt have really noticed anything other than the acceleration seems to have lost power upon launch from a stop.
These are the bloody codes that are plague my car.
Fuel trim malfuntion
P0173 Bank 1
P0170 Bank 2
P0120 TPS/ Pedal Position Sensor A Circuit malfunction
I was looking and saw that something with the pedal rod being not aligned. Im not really sure what that means. I looked real quick and it doesnt look like anythings messed up.
p0115 Engine Coolant Temp Circuit Malfuntion
What do you guys think? Im pretty sure the fuel trim malf. Is the MAF sensor problem. I think I might try to clean it tonight. Do one of these codes call other codes.

Do a throttle reset. Likely cause of all codes is a temp sensor. Fuel trim out because the car thinks it's cold. Are you blowing some unburnt fuel smoke out of the exhaust? Signs of running rich?
Could also be TPS & MAF. It's not the thermostat - that is a P0128
