Question about 1998 Isuzu Hombre

Isuzu Hombre pickup, 2.2L Vortec, Won't Start.

Hello, I have an Isuzu Hombre pickup, 2.2L Vortec engine, same as the Chevy S10. It just suddenly stopped running. Here's what I checked: ignition module (good), ignition coils (good), fuel pump (good), fuel filter (new/good), fuel pressure to fuel rail 39 psi (good), battery (good), spark plugs have good spark (good), I hooked up code reader and it detected one code: (PO452 emission control system pressure sensor low). This code can't be the problem with my truck because I knew it already had this problem, I got this code over four years ago and I just drove it like that. No new codes detected whatsoever. Have any idea's? Please help.

You need four things for an engine to run. 1. fuel 2. spark 3. compression 4. timing (spark at the right time. By your post it seems you have fuel and spark and you probably have compression unless you blew a head gasket. That leaves the timing. Check the timing and/or the timing belt or chain whichever you have.

Location or diagram Oil sending unit 98 isuzu hombre


what engine, THE CAR IS A GM s10 IN DRAG.
4.3L v6 Vortec 4300, GM
2.2l i-4, OHV ENGINE. NOT ISUZU!!!

In 1996, Isuzu replaced its Pick Up with a version of the Louisiana-built Chevrolet S-10, the Isuzu Hombre, based on the Brazilian market S-10
so google the vortec 4300
here Ill type for you....

on most v6, its near the oil gallery , on a bank.
so that means if youd look on both banks , the one with the 1 wire sensor is it.
but not this v6
its here.
log in to mitchell's and read, its all there.

My 1998 Isuzu Hombre will not stay in overdrive I have changed fluid @ & filter also seams like vacuum pressure is high like my breaks r engaged


breaks = brakes?
the brakes use vacuum but never changes it.
so...... if it does, the booster diaphram is cracked.
OD, can be just a bad OD. switch or more complex.
did you scan the TCM yet if it has one?

why state vacuum high, then not state the values seen?
you connect the gauge, and it reads what? 19inches HG at hot idle is common.
or 0.64 bar (outside usa you use BAR) as you said pressure word for vacuum and is ok in pure science that word) but make me think yoiu are not in USA? or Canada maybe....????

i bet vacuum is just ok.
the issues are with the transmission and its controls.
post is older, are you still having issues.
do say and we can link you up to FSM information on 0D.
the book covers this.... ever see a real FSM before.
the real factory service manual,, (buy one, and win?)
or if in USA , alldata.com is #1 online version of same.....
there are others, but nobody ever posts the country
making most answers wrong, including MINE.

i only have questions, after all im blind cant see car nor open hood.
so... what engine is there, transmissions match engines. so....

omg its really a chebby. Chevy
The pickup was also sold by Isuzu as the Hombre from 1996 through 2000, but only in North America
its not ISUZU at all.
you should know this and post to chevy, S10
2.2 liter or 4.3L engine
my guess is 4.3L with Brazil front sheet metal.

there are 12 control lines from the PCM puter,
and the transmission,
to find out why the OD fails
we first check all fuse..... (on all electric fails we do that)
then check levels hot, by the BOOK.
then scan the PCM for transmission errors, P07xx ? codes>

i look at the alldata. com at the Hombre 98 , pcm page.
schematics.
od .
we make sure no errors from PCM
then check the switch, to PCM for OD active.
if the input is ok.
then we check the solenoid voltages in OD.
if correct then the problem is ok, outside trans, and not inside.

This trans is electronically shifted.
and uses a computer (TCM)
so inputs must be right to TCM
an outputs correct. if not , never blame the tranny first.

Update to this problem: Told to try starting fluid, no response.


Get a good psi reading on the fuel pressure. These engines are very picky if the pressure is + - more than 7psi it will not open the injectors correctly.
Is it a vortec?

2000 chevy s10 bad thermostat


the thermostat is located just above the fan shaft, or ontop of the water pump. at least on the 2.2? and 4.3l engines. Which i think was only available. You may have to remove the plastic Vortec cover to see it.
