Hi all-
Never really had any feedback on all of the other threads, but I did "fix" everything for about two months.
Now the truck is dead on the side of the road with codes 126 and 327. I've replaced the MAP sensor four times in a year now (under warranty and swapping brands).
126 is the MAP sensor code again.
327 is EGR low voltage.
I changed EGR solenoid, TAB/TAD solenoids, and everything out in 2015 and 2016. We also replaced the TPS last month along with the MAP warranty. I think there is a new EGR valve was replaced in 2016 also, if not 2015.
I've been going through YouTube and Online looking up symptoms, causes, etc. So far one very possible cause for the EGR and MAP "effect" is a bad 02 Sensor. I have smelled rotten eggs occasionally over the last two months.
My mechanic just put an new O2 Sensor on for me a few months ago. I think I purchased it off RockAuto, or from NAPA.
Does anyone have any advice here? Can an O2 Sensor fail so quickly? It appears that if the O2 Sensor has gone bad that it will fail to send voltage up to the components that were a problem (MAP, TPS, EGR). Is this correct?
Appreciate any advice. I'm trying to have this truck stop breaking on me so I can take picture of it, cleaned up. I just had a bath but needs another one. Under the hood is pretty but the motor mounts are worn and the engine moves 4-12 inches right now at times (we're changing those out soon when I change the oil pump and oil pan). Hopefully will take photos after that phase of "rebuild."
There is light rust on the wheel wells. This Summer, if it's alive, I'll buy replacements and start fixing the body since the rust is now becoming evident.
Thanks again.
