those are good voltages, but the feeler gauges setting coordinates, timing of the TPS cut in and cut out and is critical setting on all G16A TBI engines.
your +5vrefr , voltage is ok, its from the ECU 5v reg, and yours is perfect.
leave it be, or risk damaging the ECU.
45 DTC errors,
means the ECU (did you reset and retry it?) the ECU saw the idle switch closed, when vacuum dropped greatly.
it thinks you stepped on the throttle pedal, and the wonders (sic) that the TPS switch is stuck low. the ECU is not brilliant, it only knows , the switch, plenum vacuum. and RPM and throttle angles, in many cases it can get confused. (would take a bad MAP to cause that, manybe)
so it sometimes can mess up. but that is not what i think is going on, what I DONT know, is if you are RESETTING the 45s.
DTCs are stored in memory, and old data is pretty much useless , after all it can be 6 months or a year old data.)
you have 2 symptoms, only, surge and 45s.
the sure are related.
Its very hard to get 45s , im also told that some ECU mix up these 2 codes. 44/45/?
i need to know if YOUR TB has an air bleed. screw
the bleed screw was added to ours in 1991,
but if missing means, the calibration is totally different.
when the idle pin (TPS Pin c)wire is cut, the voltage goes low , the ECU has a pulldown resistor . for safety, down means , control idle now. .
89-95 usa.
what that means is if the wire is cut, the 45 happens.
or if the TPS is bad. same (bad switch)
or if the TPS is set wrong, same. that is, calibrated wrong using the wrong feeler gauge or guessed it or done wrong.
tell me the bleed answer first, i should have asked first. A photo front of TB would help. and if the idle stop screw is slotted, and not Allen internal hex.
the top of your TB should look just like this, exactly
if yes, the feeler is 0.016? (Dash pot retracted, we turn the TPS body until it just hits, below 300 ohms) on the threshold, ( infinity, infinity, then bam below 500 or 300 ohms) lock it down. Do not allow over/under travel of the TPS, it must be on the threshold.
did you reset the ECU DTC errors. and drive to see if the 45 stay cleared.????
