Intake Temperature Sensor Connectors

[MatrixRSi]

Ask: Can someone please unplug their air intake temperature sensor and tell me if their plug has two gold connectors (the plug, not the sensor itself).



I replaced the throttle body actuator last weekend but I got a new code from Carly: air intake temperature sensor. It wasn't a problem before. When I was putting everything back together I felt like I may have pulled the connector and maybe one of the wires pulled out of the connector. Why do I think this?

The actual sensor has 2 pins and my plug only has one gold connector in it.



- I have pulled away the plastic cover from the plug and there is one wire (greenish/red)

- I have tested the connection in the one side with a circuit tester and it is getting power

- I cleaned the sensor lightly with alcohol

Maybe I just need a new sensor but if I pulled out the wire from the plug that would be a real headache. Please let me know if yours only has one.

Yes the IAT sensor wire has two conductors. The oil pressure switch just below it in the oil filter housing has one conductor and a similar connector. Is it possible that you accidentally mixed up the two?

If you pulled out one of the wires from the IAT connector by accident, it should be a short process of relocating it from the area... If it damaged the housing or wires, BMW sells a replacement pigtail (PN 12517841385) since technicians commonly damage this when removing the plenum.

Many thanks for the detailed reply!

Hi Matrix, don't mind can you tell me how do you remove the sensor out? I can't seems to remove it despite being able to turn clockwise and anti clockwise, but I still can't plug it out.
Thanks.

I cannot find the connector for my intake temp sensor. Can someone show me where the connector comes from and where it is?
