problem with TPS sensor
#11
now what idle speed means. EFI, 1989 g16 up.
The ECU sets idle speed not you. (in a servo controlled closed LOOP) if ISC is dead the stop screw does change idle RPM, and is the clue #1 ISC IS DEAD. (a fix first issue for sure)
The ECU is hard coded (accessories off) to 800RPM -+50rpm and regulates there, via said loop.)
The ECU does this magic using only (hot engine) the ISC valve solenoid top right of TB. 2 wires. ISC = idle speed controls.
The ECU modulates this from 1 to 100% at 12vdc. this 200Hz modulation is called DUTY Cycle.
Duty cycle is set to 50% hot.(by shop calibration steps) engine using the TV stop screw (far bottom screw)
this adjustment means the ISC can lower or raise the RPM by 50% of its authority. (revolutions per minute, or R/min)
about 400rpm range of control but varies. by age of engine and say vacuum leaks. oops..
what this magic does is when the engine runs too slow the ECU sees that as spark RPM drop and the ECU opens the ISC to gain 800 rpm back.
this is also used with AC turned on and rpm goes to 900 to 1000 RPM by ECU command, (RPM varies by year car ECU)
that is how ISC works, in brief.

hello friend, I found a sensor tps for my suzuki vitara but my surprise was that it was also in bad condition like the one I already had, I found an entire inecitation module with the collector but it is the year 96.es possible to be able to attach it to my vitara of '89, a greeting

sorry not sure what you are saying there,
but there are like 5 generations if TPS. 89 to 99.  This car is 8valve so only 8v TPS fits.
for 2 engines. and outside USA lots more engines, even v6,  and 1.8L  and more.


if it can be mounted, most can function correctly wired correctly
it is just  variable resistor.
3000 to 5000 ohms , note the crude range making this part easy. it is NOT ANY KIND of accurate resistor at all.


what is this? inecitation?
good luck to you. !!!!

inyecion forgives, not incitement.ok do I understand that it is possible to place the module with the collector of the year 96 in my vitara of the year 89, is it possible that you have problems when adapting the AIR hose of the ISC? in my vitara is electric, where I have to place it ? thank you for your help friend, a greeting

my guess is this questions is all about , using the wrong throttle body, and worse yet 3 generations removed.
89
91
96 is gen 3 and 16valve only in USA but in for example they made 8valves too, now illegal in USA, (EPA regulations)
the answer is no,
the injector it itself is not the same and as you see the radically different ISC , even the coil inside the ISC is 2 times different in ohms (6 now 12 ohms)
https://fixkick.com/sensors/tests/IAC-E-tests.html
yours is 6ohms not 12.

all ISC are electric and the IAC is water thermally controlled, both are idle speeds, the IAC WORKS ONLY ON COLD engine below 150F degrees. in fact
the ISC has many jobs but the #1 is idle speed controls (ISC) this works full time at idle. HOT.
it also is used for other odd things, for one thing it prevents drivers head snap at radical deceleration, it opens a bit to avoid this act.

you need to stick to 89/90 parts, if called Suzuki on the phone that is what they tell you.
nor use Jimny parts, (samurai here) they are not the same parts ok?
the 89 has many different parts, like vacuum lines wiring to injector ISC and different PCV valve hoses and map hoses and more. lots of things very different.
even the intake manifold is different to match up those above differences.

good luck to yoiu.

and CHEERS ! and good luck to you!

Hola amigo, ya he montado el módulo de inyección del año 89, la vitara para arrancar muy bien, pero tengo un problema, no consigo que baje de 1400 revoluciones, ¿cuál sería el problema? un saludo muchas gracias

you said
Hello friend, I have already assembled the injection module of the year 89, the vitara to start very well, but I have a problem, I cannot get it to drop below 1400 revolutions, what would be the problem? Regards thank you very much

google translator.
is the engine hot 180f "? if not and is cold 1400 is normal on cold engine, 800 RPM is only HOT engine, (means normal temp)


this car is no longer stock. so photo photos of this. Throttle body.
here are the facts , on this car, this engine runs off MAP (speed density system, no MAF)
this means all vacuum likes (sucking air) cause too high RPM
and means the ISC is dead or the leak is too much, if any leak is too much air sucking in to the intake ,that means it must idle too fast.

ive no idea at all what you have there, for throttle body, not me.
but on 89 , turn the throttle stop screw CCW counter clockwise to lower air flow and idle RPM.
vacuum hose leaks too.
IAC bad, in base of Throttle body can do that too , the thermal air valve stuck open.
the idle up circuit is active.  causes 1000RPM or near,
that is about it.

-------------google revers translated------OMG help----------
¿el motor está caliente 180f "? si no y está frío 1400 es normal en el motor frío, 800 RPM es solo motor CALIENTE, (significa temperatura normal)


Este coche ya no está en stock. así que fotos de esto. Cuerpo del acelerador.
Aquí están los hechos, en este automóvil, este motor funciona con MAP (sistema de densidad de velocidad, sin MAF)
Esto significa que todos los gustos de vacío (succión de aire) causan RPM demasiado altas
y significa que el ISC está muerto o la fuga es demasiado, si alguna fuga es demasiado aire aspirando a la entrada, eso significa que debe estar inactivo demasiado rápido.

No tengo ni idea de lo que tienes allí, para el cuerpo del acelerador, no para mí.
pero en 89, gire el tornillo de tope del acelerador en sentido contrario a las agujas del reloj para disminuir el flujo de aire y las RPM en vacío.
la manguera de aspiración también tiene fugas.
IAC malo, en la base del cuerpo del acelerador también puede hacer eso, la válvula de aire térmico se quedó atascada
El circuito inactivo está activo. causa 1000RPM o cerca,
De eso se trata.

SALUD !!!

The engine needs to be hot.
The RPM goes to 800 at 150f and higher,
the IAC closes 100% at 150F then the ISC now controls idle at 800rpm
not in idle UP mode, ECU pin called idled up must be false. (AC off, blower off. PS overload switch not active,head lamps off)
if all that functions ok above, then the ISC holds 800rpm
if you fail to calibrate the ISC with the 89 idle stop screw that too ends in wrong RPM
and last any and all vacuum leaks, cause high idle is said leak exceeds range of ISC .
use google translate please.
there is more
if the thermostat is missing RPM will never be correct ever,
if using wrong low temp thermostat the same think 180 to 200F stamped thermostats only are to be used .
good luck to you.

I do not understand what about the translator, I apologize. The engine if it is hot, it is possible that IAC does not work well? I will try to check all the tubes and see any possible leak. Closing ISC in the direction of relog need to lower the speed ?Thanks for your great help
