Yes the engine management is improved by accurate inputs. I get a smoother idle (still not perfect hoping a map sensor will do it, but I have no cat's and kleemann's so I don't think I can expect a smooth idle. I haven't had as harsh supercharger clutch engagement since I replaced the sensor.
This was a big one for me esp because I have a bigger crank.
Good job brutha AMG M113 engine folks. I was the CL55 AMG OP for the "AIT sensor woke up Godzilla". To clean the injectors and anything else fuel related; yesterday, a 16 oz. can of SeaFoam was placed in 6 gallons of gas already in the fuel tank, then 8 gallons of gas added to tank. Today, the TB will be cleaned as per MACEDON's procedure, and the K&N air filters cleaned and oiled.
I think what he's saying is that sensitive electronics are especially susceptible to filter oil. If you look at this sensor right next to a typical Maf (without the plastic over it of course) they don't look much different. In fact I'm surprised they don't fail faster seeing how much oil film my intake is covered in, coupled with the high heat.
Just replaced mine today. Might as well replace the air filters while you are there.
Seems they updated the design a bit. My car only has 40,000km but still the sensor was somewhat oily. No oil at the throttle body at all though.
I found I could get the sensor out intact by using some needle nose pliers as below. You cannot grab it from directly above due to that metal pipe in the way but you can get at it from a slight angle from behind. I tried initially to break the clips but this was very easy once I worked it out.
Hey, does anyone know what is the name of the connector used here. My connector has one wire cut so I would need to replace the connector with a new one but do not know what to search for.
