There is a 16 pin diagnostic connector box in front of the battery..
Open the lid and you will see a button and a Led ...push the button with key ON and hold it for 2-3 secs..when you release it, a code will flash back..keep doing that until there are no more codes. [ until the first one repeats]
After each code , wait 2 secs and hold button for 8-9 secs for each code..that will erase that code ..do them all and then turn key Off for 10 secs , On for 10 and then start,,that will put the CE out.
Write down each code and post them here, just for kicks.

After you do that . I will tell you how to get the Memory back to mean base line so your new MAF doses not have to readapt...
