This vehicle has what is called fly by wire with an electronic throttle body. This vehicle particularly has had problems with poor grounds at the intake manifold and broken wires by the connector at the throttle body. The best solution would be to have an expert properly diagnose the problem with his special equipment.

What exactly are these error codes? you may have a problem with fuel delivery that comes from oxygen sensor and temp sensor but need to know what those codes are. fuel deliverey is set by the temp sensor and the 02 sensor so if these start to fail you could get a problem like this and the age of this vehicle lets the 02 sensor be a likely suspect. please get back with me and good luck

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?

2000 izuzu rodeo reduced power light came on, it starts up but immediately dies. Read all the following codes p0502, p0401, p1125, p1295, p1515, p0137, p0106, p1299


check all fuses to start with. then check all grounding points... for that many codes usually means a bad pcm or loose ground wire..

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

Diagnostic code for isuzu rodeo p1125,p1295, and p1550


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?

Can my transmisson on my 2002 isuzu rodeo be low on fluid.It does go into gear but .But it does not go very far.Like the transmisson is slipping


I suggest bring the vehicle to a repair shop to :
a) check for leaks and ATF condition ( burnt smell ,shavings, and coolant in ATF) Any one of these conditions may indicate a rebuild.
b) if no leaks are found and ATF is in decent condition fill tranny to proper level and check for slipping.
c) if slipping doesn't happen after level is brought up to specs, DO a transmission oil filter and ATF change.(and be thankful you gotta away cheap.
d) if slipping still happens after level has been topped off
they(repair shop) will either "Stall Test it or pressure check the transmission " Good luck
