SOURCE: ISUZU RODEO SPARKS PLUGS CHANGE OVER

In the center of each valvecover is a well with a wire in it each wire has a seal cap attached pull up and youll find a stem which goes down a tube this is part of the spark plug wire the plugs are at the bottom of this tube youll need a long adapter on your wrench and socket for this job and you can extract the plug using the wires stem

Well, if it isnt broke, well you know the rest. As a kid in the shop we were directed to add dextron 3 to the fuel to decarbonize an engine. I have practiced this and my ford 5.8 that just hit 280,000 .. Cant say that was it, but point being it didnt hurt it. They actually make a old school fuel additive called Marvel Mystery Oil, It is Dextron 3 mostly. The oil consumption test you can do, Do a oil change , after 1000 mi. drain it and see that you have what you put in. That is what they are charging you too do. Is it worth it? umm, no

After market spark plugs could be the problem.
Reinstall the old plugs and see if that fixes it.
This vehicle has an ion sensing ignition system and is real sensitive to the proper spark plugs. I would get the proper plugs from the dealer if the old ones work.
The codes P1311 and P1312 are ion sensing codes.

SOURCE: diagnostic code for isuzu rodeo p1125,p1295, and

P1125 is: Throttle Positioning Sensor intermittent.
P1295 is: Multiple faults on bank 1 (right)
P1550 is: Power steering pressure sensor out of self test range.
Well the ECM recognizes 3 codes. Were these codes stored as inactive (in the history section)? Or are these codes all active? Code P1125 and P1295 may be related but P1550 is separate. How else may I help?

2004 isuzu rodeo codes P1125, P1295 and P1515 what do they mean ?


no engine stated.
answering for usa rodeo. only. on a usa forum.
it means trouble; the factory manual covers this.
As does mitchells DIY online, read that much>?
those are called DTCs , scan codes. diagnostic trouble codes.
The PCM looks for problems all the time running,
CALLED MONITORS (a sort of nanny)
all cars do this 96 to now, in USA. by law.
If no book or no mitchells try google (or the like)
if you had you'd have seen isuzu examples.

but google finds this in 1 click.

the great justanswersl.com (ASE Techs)?
1125
1295
1515
DTC P1125: ELECTRIC THROTTLE CONTROL (ETC) LIMIT PERFORMANCE MODE.
2nd hit.,
P1125 Isuzu Electronic Throttle Control Limit Performance Mode P1221 Isuzu Throttle Position Sensor 1-2 Circuit Performance P1295 Isuzu Electronic Throttle Control Power Management Mode P1515 Isuzu TP Sensor To MAF Sensor Correlation


the first hit said, bad grounds top engine to PCM
and bad harness wires to above same place.
but as all techs, no, bad wires, happen all the time.
as do vast other reasons.
what I do , as the FSM states, clearly
is pick one failure and correct it, and sometimes gets them all.
like blown fuses do, on all vehicles.

1125 means limphome, is in force Low power too.
the TPS is acting up.
the 1515 means in English
that the Throttle angle and air flow dO NOT JIBE.
my jeep books calls that "incongruity": (nicer word)
or they differ. and should not.
i'd be checking the TPS voltages. for correct voltage.
this can fail for wires, rust, and bad sensors.
the word performance means it reads funny. (wrong)


we use a real scan tool and a real volt meter to see what the readings are on these parts.
why not get a real ASE tech to find it.
they know all that electronics magic,
ALL learn that there can be false codes.
one failure can trip many codes, but only one is the fundamental code.

or vacuum leaks cause many errors but not one
states vacuum leaks.
see?

P0300 and P0303 misfire codes 2004 Isuzu Rodeo 3.5L


so missfire detected and cylinder 3 missfire detected.
check to see injector pulse with "noide light" if ok injector is problem
remove fuel rail and injectors look into top of injector for blockage in screen filter in injector if blocked clean out or injector carby places can remove this screen replace it and test injectors and clean or just buy new injectors. make sure to clean out fuel rail and change fuel filter also.
if noide light flashes irratic or not at all wiring issue, check for power on one wire with ignition on 12v other is earthed by ecu when opened to inject fuel. other thing that can cause problem on cylinder is tappet clearance "shims" too tight, could do compression test to see if compression is low on cylinder or a cylinder leakage test to see if valves are leaking. broken valve spring. valves do not hit piston on these engines even if cam belt breaks, they are a "free wheeling" engine

I have 3 codes p1125, p1295, and p1515 and was wondering what they are


p1125 tells you the vehicule has gone into (limp) mode or reduced power. p1295 will direct you to a problem with your Throtlle position sensor and p1515 fault indicates theres a problem with the corilation between throttle position and commande giving.

i own a 2001 rodeo LS 3.2L and had this codes show up. The machine had really bad idling and when accelerating quick after first start would go into limp mode and not pick up speed pass 50 kms. i tryed changing the throttle position sensor.. nothing. tryed changing the spark plugs and noticed they looked unusually white (engine running lean) i put injector cleaner in with i freash tank of gas thinking the injectors were dirty and it seemed to help. Next a changed the fuel filter which completly solved my problem. at the last oil change they told me they changed it but didn't the inside of the filter was rusted and clogged starving the engine of fuel.

Problem solve for 15 $ after you change your filter take it to and auto parts store with a computer to reset the engine lights
