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 (ASE Techs)?
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.

What fixes codes p1515

Throttle Body Sensor or your accelerator pedal is the cause of code P1515. Your GMC or Chevy truck gas pedal is controlled by the vehicle's computer. I know what a idiotic feature.. But replace that & clean or replace your mass airflow sensor as well... Problems resolved!!!

Driving my 2002 chevy trailblazer then went to the store shut it off now it wont start pulling up p1515 code

P1515 indicates the Throttle Position Sensor. Look for it's location at Autozone .com or other site. then replace it. Hope it works out good for you

Mfg spec codes p112p1295 and p1515

p112 is not a code. The other codes refer reduced throttle or limited throttle command. These codes will most likely set when there is a problem with the electronic throttle control. The most common problem is a break in the engine wiring harness to the thottle body.
