hello;; 95 Tracker, 4WD, auto, vin 6, 1.6 ,16 valve, made in Canada and Cal emissions. no scan tool. (ouch)
sorry for you ordeal: it can be perplexing, but with a volt meter, we can find it. got one?
how do you know the old maf was bad?
You car has CEL lamp and a diagnostic jumper. when jumped does the CEL flash 33 or 34, bad maf? if not, then the ecu is not in MAF induced Failsafe.
and what is the voltage on the old ( all 3, keyon, idle and 3000 rpm) ? only that matters. (focused on MAF only)
its running very rich, that Maf you bought is a clone, and i have one here, its its stuck at 2.50 forever (running), until I corrected the wiring blunders inside.
it's form China ,see the china hanzi script on top.? and no 58B00 Suzuki marks on the side, like all real MAF have.
Sure no return, after all , 1/2 are no good out of the box...?
what is maf output at 3000 rpm , this clone was 2.5v , again, a dead maf. what are the 3 outputs. , keyon, idle , and 3000.
that is correct ,unplugging the maf , instantly drops the ECU to failsafe, with CEL flashing, 34s for ever.
in some cases it might run better. that dont mean anything, after all that is what failsafe is; a way to drive to the repair shop , with limited power.
have you discovered the paper clip.?
you can drive it with that in in place to see of other DTCs pop up.. 12s are normal. A great ploy to find intermittent failures (hard)
see jumper rules on this page.

Backprobe one of the DVM leads to ECM terminal B8 , and the other DVM lead to a good chassis
ground. Turn the ignition switch ON and read the voltage of terminal B8. The voltage observed should be 1.0
