Hi all!


Some days ago my CEL lighted up. I did run the codes and got KOER 998 and 157.

157 - MAF sensor went below 0.4 volts during the last 80 warm-up cycles.
998 - Hard fault present


first i did not know what to do. I started with the cheking the MAF and there it was.. the MAF connector was little loose ... plugged it off and on and CEL was gone.
Hope this helps someone.

Have a nice holidays
