Low 5v ref

[fixkick]

Hey there mr fixkick

    Thanks for all the info.
Couple more quick ones before I fire this pup up again. The mafs got 12v to it So it’s def bad. Ok.... NOT TRUE at all
the MAF is a fully electronic sensor, it has a AIR FLOW SENSOR AND AND AMPLIFIER CHIP INSIDE, THAT NEEDS POWER TO RUN AND THE PIN MARKED 12VDC (10 TO 15V)  MUST HAVE POWER ON THAT PIN OR ALL MAF FAIL HERE, ZERO POWER GETS YOU ZERO OUTPUT ON PIN 2, PIN 2 IS OUTPUT, ONLY. (CENTER PIN)



1-can I wire the sensor(un-named) ground straight to the battery? THIS TOO IS WRONG, SOME SENSORS have  a special ground wire to the ECU this special ground (sense) is MONITORed
and if ground is weak the ECU compensates for that error (tiny sure  but IMPORTANT) why do you hate factory wiring or paths..



2- can I run the car without the ect maf and o2sensors?... I Caint find anything wrong with any of them or the wiring.  ( the outputs matter, first we test outputs only to begin)
there is no need to do that unless limphome and 10mpg is fun? and black spark plugs and black smoke out tail pipe.

      Also if I can run without all the sensors in that 5v ref circuit thought I would wire the grey yellow ground separate- straight from ecu to tps to make sure it wasn’t picking any vol anywhere. That way would be eliminating anything but the tps wiring?? FOR SURE, running new wires, for sure cures a bad foctory wires but must be wired the same way.
ECU to sensor. (MAF is unique ok and is wired , power and ground different from all other sensors) The  TPS just needs 4 wires working. as Suzuki made it.

no SUZUKI nor any car with bad 5vdc will run correctly, ever, lacking 5v,  the ECU goes to limphome gross then.

        Thanks for your help!!

inline answers.

you do what ever you want to do. it is your car

seen these old pig CARS 4WD, used in a forest, tree cut, and log and bucking job , used to drag hug limbs.

that are in limphome for ever,  10MPG horror fuel usage like this, and fouled spark plugs every day.

some what it to run right
others are happy if it make noise and can move say 50ft. logging.

what matters top you ive no cue.
you are welcome, but we can fix all problems that is for sure and most  have big problems., old.
