I just cleaned my TB with car off and on, plugged everything back securly the way it should be, but for some reason i get a CEL. I took it on the highway for a few minutes, left idle too yet CEL still doesnt go off, yet the car seems to run fine. Quick help is much appreciated. Thanks in advance.

 

1. Did you pull the code that is being shown?
2. Did you make sure you plugged in the MAF and IATS sensor connectors?

 

Double check your connections, then reset your ecu.

 

All connections are in, and i get 0505 thus no failure. Any reason why CEL went on then?

 

Just reset the ECU and if no new code reposts then you have nothing to worry about.
