95 tracker miss after warm up

well while driving it threw the tps code... never done that...

well while driving it threw the tps code... never done that... (hint they all do this old or over 100k miles)

Which code? 21,22,44,45?  there are 4 errors possible one sensor (device)

know that codes are live errors, driving and can in fact self clear as soon as the happen
even clear in 1 second.  (all are real, they never lie the ECU sees this and is always real)
that is why driving and logging , works best no matter how done.

on new cars 96+ we log to PC, laptop, and see IT ALL.every thing at once captured. (live sensor data and DTC errors both and lots more possible)

on this car it takes humans looking at the silly limp flashing and is only crude errors
means dead sensors, and can in fact be intermittent. (old cars do that, worn out parts or calibrated wrong)

TPS bad can cause TIP-in misfire.  (as in right foot tips in the throttle,TIP of foot)

There really are 2 TPS here (4codes) one is the throttle angle and the other is and  TPS idle switch.
both can case , tip IN,  throttle stalls, misfire or hesitation at any  (angle sensor )speed. (it is really TIP in lean out)

what happen is this ,  for TPS, errors. (ECU goes nuts seeing this error , running the engine,)
how does this work:?
easy.

The fact is that THE TV allows huge air flows into the induction with a super fast right foot worse case. (and rule one air does not burn)
the causes huge vacuum drop that the ECU sees way too LATE,  do to slow actions of MAF(16v) OR MAP (8V)
THIS CAUSES a super LEAN CONDITION,
but the designers know this and...
the cure is a TPS is fast as 90% of the speed of light, (the TPS sensor is that fast) and the ECU sees the foot fast and goes super rich fuel mix. to get full power and not a bog, or misfire. lean.
That is how all cars work EFI. every  one, do to the slow MAF/MAP. (
back in CARB days, Carberetter, the high speed accelerator pump did all this. instant rich fast foot. on EFI this is now electronic, no more Carbs.


the TPS on this car is calibrated by hand. if done wrong or the the switch is bad? ot fails and other effects told below...
the idle controls (late TPS) fights your right foot just off idle,  this can be profound this fighting. (gross hesitation)  and does not effect driving fast, ever. only idle to off idle transitions. The main TPS throttle angle part can fail at any speed, any TV angle can fail do to bad carbon inside, the TPS, (dead spots)

what code (of 4) did you get, all codes matter big time and they all mean gross error detected. as in Very important.

good luck to you.
hope you like my theory talk on how EFI works,  and some race cars only have 1 sensor, TPS, due to running on track mostly full throttle.
they run rich full time. for max power about 12:1 AFR  fuel mix. or in drag racing.

progress,  finally , with TPS errors, (no matter how long or short, all are KILLER BAD)

it also causes , FAIL safe for the duration of the failure,  and  super complex effects that. "ugly" on any 89-95 that

[fixkick]

causes all (tps errors)
1: there are 3 throttle cables, one for 3 speed trans, 1 for cruise box and one for drivers right foot. what you have on car I do not know. (options)
if any are not set loose this makes the TPS fail. the throttle main cable to foot is set with 10mm slack(almost 1/2 and inch) in the manual it is. how to do all those.
2: TPS not calibrated per manual with feeler gauge set. (cause only error.44 /45) switch failure for this or line 1)
3: TPS is bad. (both switch and angle side can fail)

this sensor bad cause tip in bogs, not misfire, misfire is spark only , bogging is lack of fuel;. as in can not burn air , lean.

misfire too can be one injector failing and 1 cyclinder going dead or at radome.

TPS errors must not be ignrored. ever.

Sorry... its flashing 22 the low voltage one... ive tried clearing it and it keeps coming back... pretty sure the components on this car are all stock as i bought it from the original owner. other than wear items that i have replaced a few times... the egr is replaced by a resistor. the rig has run fine until this issue with the timing bouncing around....I didnt know what it was until the recent revelation.  has been doing it intermittently for awhile. would the tps low secondary voltage  cause that issue... it never through all the times it did this showed this code.

22 DTC error code, "diagnostic trouble code"  (it is true that it can come and go in 1 second) that is why we look , constantly.(when there is trouble)
and when it does fail even for 1 second the ECU goes to limphome mode and RETARDED timing is the effect (spark) this is normal for any DTC mostly.

this error is a catastrophic error code.  (means must be cured first !) on all cars made, EFI.

TPS  Throttle Position  Sensor Circuit is too low V  , TP pin, not idle.

this means the TP pin wire, is dropping to 0volts. (too low is that)
it means  ONE OF , 3 things,

• the +5vdc pin  is falling to zero volts  at pin 4 , or pin 4 wire is broken. (I do not think it is ECU bad or other sensors would fail) this is a power pin !
  
• the TP pin wire is broken., at pin 3. (or its pin socket damaged)
  
• or the  TPS is bad. (EOL< end of life) 
  
  

pin 3 below is the failing. at the pin called (TP or throttle position) 
All the ECU knows it the voltage on pin 3 fails and goes to zero. (1v to 3.5v is normal range. idle to WOT) 0v and 5v are wrong.
TP is also throttle angle ! (the new modern name)



if wires look ok, most times the TPS is bad.
most times the TPS has dead spots. seen here. (from endless wear from decades of use)

more , on topic
car 26 years old
at as 10,000 miles per year, that is 260,000 miles?
now many TPS last that long, zero?
think about that, and how your right foot wears it out every time you push your right foot even a tiny bit.
yah. the carbon in the pot inside wears out as your drive the car, for 26 long years.
there is that.
the FPR is the same thing for the same reasons, it moves even more. for load changes.

tires, belts ,hoses, brakes pads, fluids and TPS and FPR are short lived parts. most do not make it 300,000 miles. ( life of cars are in that realm)


buying parts for old Sidekicks is painful.
nobody on earth seems to know there are 2 engines in the car, 8v and 16valve, yours latter.
but sellers are clueless on this, and sell 1/2 their customers the wrong parts. even here.
the one clue is the wrong sensor has pig tail. not the 16v ever./
they are not cheap at all, this sensor as the suppliers stop making them prices rise, (no more Delco, oops. nor more
TBI is wrong
MFI/MPI is correct
as is 1342058B00 (key code here is B58 not B56) B58 means 16valves.

Thanks... I hope they are gold plated for that price...lol.....  hope that solves the timing change issue... should be here in a week.

only place that might be cheaper is advanced auto (none) or autozone  has the best price.
never skip walk in auto parts stores, some might have the parts and be cheaper.
SMP is the top maker here, that has the most parts for this car,. aftermarket but is expensive.
 
suzuki wants $336 for TBI and , MPI not in stock calif. listed discontinued there
now east coast SUZ , New Jersey , same discontinued.
1342058B00  (the true p/n)

let me tell you one more reason this sensor can be wrong bought, of the 3 ways, 1 right ,2 wrong, first wrong is TBI engine
and the 2nd wrong is 1997/98 TPS was resized by suszuk and shunk flange, making it very easy for sellers to get this all wrong

https://www.autozone.com/engine-manageme...1342058B00


to be sure carry yours in, and ask for TPS494.  duralast for $130.
make sure the flange side fits.  MPI is built in connector and , the flange 92-95 fits.

the DTC error is not ever good. even 1 second long , nasty limphome goes in to effect.
all spark advance ends (you saw it) it is not a surprise this at all.
idle speed controls are suspended.
engine goes super rich and fouls spark plugs
burns up the CAT easy.
15MPG fuel usage (horrid) only if DTC holds solid fail.
89-95 were the worse, rich as pig fueling,. if cat is not there (missing or roddedout) see black smoke huge at tail pipe end.
96+ far far better, same rules but not anywhere near as bad. effects. (EPC knew all this and forced a correction, 1996 OBD2 et al....)

LIMPHOME mode is never fun. it is only for making car drive home, and not get stalled in the woods. or in snow drifts, etc..
