Hi,
Has anybody ever taken the throttle housing (incl. stepper motor) of the 2.0i 16v engine apart for a clean??
My Xm is a bit jerky when low in rpm (around 2000 rpm) and touching the throttle slightly. It works absolutely beautiful when accelerating hard.
I think that by cleaning the sensors in the housing (air temp/volume and throttle?) and maybe the stepper motor it will improve. Then again I don't know if there is anything to clean...

there is not a lot to clean on temp sensor is just a reed sensor hanging in airflow. you can wipe the dome end of the stepper motor but DO NOT force it in and out or you will damage the gear. as far as throttle butterfly just open butterfly and clean with toothbrush also make sure air holes are clear.map sensor just check for clear intact pipes. I would also invest in a proper citroen diagnostic report.
Hi,
Sorry to keep digging this back up. I had a look at my throttle housing yesterday evening and found there were three connectors on them as well as a stepper motor.
Two connectors are on top of the housing, one of them stood out because it was yellow and had a sort of plastic bracket on it. The third connector is on the bottom of the housing.
Can anyone tell me what these do. (I'm talking about the RFV engine with the Motronic 5.1.1 ECU)
Also is there eny sealant between the housing and the inlet manifold it is bolted to? I haven't been able to find the MAP sensor yet.
