This code sets when the indicated o2 sensor rich / lean transitions are less than the specified amount that the pcm wants to see. You need to determine if these sensors are staying lean, (possible vacuum leak,weak fuel pump for example) or rich(faulty map or mass airflow signal, or leaky injector for example) Either code can be a faulty sensor also,but there are many other things to consider before throwing parts at it. Your first challenge , is using the data stream to see what the sensors are telling you, and then to determine what is causing this. This is what drives real mechanics up the wall, people go to the auto parts store, get codes read for free, replace o2 sensors,and it turns out to be a vacuum leak. Believe me, if there was a machine that just told you what's wrong, we would all have one! Let me know if I can help furthur, glad to do it!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?

What is Saab code 1125 &07E8


The code 1125 is your throttle body, when they get dirty or stick they toss up a code. It will need to be replaced or cleaned. On Ford or GM cars we just remove them carefull not allowing dirt or tools to fall in after removing. Get some carb cleaner and clean all the dirt and carbon grime, out of it. be careful not to damage the sensor. Ask shop about cleaner you use not sure about safty on car made in Europe. Put back and things should be ok, If not you will need to replace it. Other code I believe is a junk code. readers seem to be not able to read sub codes unless it is from factory.

2000 isuzu rodeo shuts off when driving is reading codes 1125 and 1299 has been in shop and throttle body was replaced still having same problem as first time before throttle body was replaced. it happens...


A shop will guarantee nothing based on our guess. They need to be able to find the fault and make the recomendation.

If I said you needed a computer at a cost of 600 to 1000 bucks would your really trust my advise and just do it.

I know its hard but this has already been to the shop. They had a birds eye view with all the tools of the trade.
We have nothing to work with here.

Diagnostic codes


P1226 Control Sleeve Sensor Malfunction
P1126 Throttle Position (Narrow Range) Sensor Circuit Malfunction
P1125 Throttle position sensor intermittent
I would say u are safe to assume the trottle sensor is defective or the wiring to the sensor is open or shorted. check the connector for pushed out pins.
