Hey guys... I've had this pesky Cel for about 2 months and finally got a friend to check out the codes.

17509 - Oxygen (Lambda) Sensor:B1 S1:Voltage too Low / Air Leak
________P1101 - 72-00 - Cylinder 5
16555 - Shareware Version. To Decode all DTCs
________P0171 - 93-00 - Please Register/Activate
16558 - Shareware Version. To Decode all DTCs
________P0174 - 92-00 - Please Register/Activate
17658 - Shareware Version. To Decode all DTCs
________P1250 - 72-00 - Please Register/Activate

Any Idea on how to fix this problem?

16555 & 16558 are system too lean.

17658 - Fuel Level too Low


Seems as though your MAF has taken a dive?

coolant temp sensor went **** up. I'm not saying that's your issue because it's not throwing a temp sensor error, but all my other system too lean errors went away when I replaced the temp sensor. Good luck.

Common denominator is O2 sensor...

Low fuel may be just that (your tank is nearly empty) I have had that one it doesn't set a CEL but shows if you have another present.If it were MAF it should affect both 02's. You could switch sensors to see it the fault moves to the drivers side but that seems like a lot of effort.

17658 is a low fuel fault
16555 is lean mixture bank 1
16558 is lean mixture bank 2
17509 low voltage/air leak (VERY lean)
I think it's a vac leak or it was run out of or very low on fuel. Both banks running lean means the prob is common to both banks.
