CEL Codes

[TunnelFear]

I had a friend of mine pull these codes for me from my truck. What do they mean? And how do I fix it? 111(KOEO), 10, 157(CM), 181(CM), 189(CM), 332(CM) Any help would be greatly appreciated, thanx

OK.... 111 as a "hard" code means that there are no problems found at that moment. 10 is simply a separator code to tell you when you've gone from hard to continous memory codes - problems the ECM has seen in the past.

157 indicates a MAF problem.... sensor output is below minimum voltage. Cleaning the MAF may solve this problem - but only if it's plugged in....

181 and 189 are rich mixture indications. Fixing the MAF problem just might cure these as well.

332 indicates low EGR flow.... could be carbon plugging the passages or a faulty DPFE. Make sure of the passages first since this is the cheapest.

All of the codes indicate that maybe a Chiltons for Xmas might be a good idea......
