Been a lurker for years as we've owned a 1994 2.3 5spd, 7ft bed Ranger for 10+ years. Love that truck, just passed 285k miles, over 100k put on myself.
Recently purchased a 1996 Ranger Splash 3.0 Auto 4X4 with only 141k miles on it. The overall condition is very nice. I bought with the dreaded P0102 MAF low voltage code. Other than idling a little high (1100rpm), the code didn't scare me as I was almost certain it would be a vacuum leak between throttle body and MAF. Welp, after checking a number of lines and even some wires, not finding a smoking gun.
Did wind up swapping out the MAF (I know, don't start throwing parts at it), no change, CEL still triggers after a few miles.
New PCV valve and grommet, needed it anyway.
Last night while checking more for vacuum leaks I noticed a piece of electrical tape over the little hole on the butterfly valve in the throttle body. Oh crap, someone's been dealing with this for a long while.
I've read threads and know I need to start testing more of the harness to ensure wires aren't broken etc.
Looking for possible advise from any other 3.0 owners who've had to tackle the P0102 code. Ranger runs and drives out good. I do smell a little extra CAT out the tailpipe which would make sense if the MAF isn't sending a proper signal.
I do have an ODBII reader on the way. I have a scanner, but it only shows codes. The reader will allow me to see real time data.
Sorry for my first post being a question and thank anyone for any tips or places to look.
