Default Help with codes

My truck started throwing several codes.

P0154 Bank 2 Sensor 1

P0102 MAF or VAF A circuit low input

P1153

I took all the plastics and sensors off while cleaning the air filter several weeks ago. Re-installed it all and drove it for a day or two with no problems. I left for three weeks and right after I left my wife got a CEL. Any thoughts on why the MAF would have a problem?

2 of those codes are related to the pass side front o2 for voltage and switching. Inspect wires/ground and/or replace the o2 (they don't last forever) Your Maf is probably fine. Try that first.

I assume you have a K&N type of filter then. Might want to carefully clean the MAF, the filter oil can cause it to read badly.

like said above, that is proabably the reason ODBII cars have parameters and if they go out of spec for too much of a time, it kicks the code.

I first thought that the oil was the problem, but the code is for a low circuit input and not a faulty MAF. I do however plan on cleaning it out. My first thoughts were to replace the o2's as well first.

I may have bad cats which caused the o2's to take a ****. I am getting a foul smell from the engine bay area. While ideling the truck wants to stumble and idel rough. Once I am driving at rated rpm's the truck is fine.
