2001 isuzu rodeo p1125 and reduced power light and engine light

Intermittently the reduced power light will come on along with the engine light. p1125 will set and veh. will be in limp mode or forced to idle. I have already replaced the electronic throttle body but no help. I did however learn that since it uses a gm processor that you can lie to it and tell it that it is a s10 blazer and you get a p0604 along with the p1125. p1125=etc reduced power mode & p0604= internal ram error

    Its marking "throttle position sensor intermitten"  Was the TPS sensor replaced? some throttle body housing sometimes dont come with the sensor.

SOURCE: The reduced power light

Hi

You are having electrical issued with your rodeo, where the engine stalls, or misses, or you hit a bump and the reduced power light comes on here is the simple FIX (the first place you should check). On the main wiring bundle which runs from the engine to the computer module (8"x8" light metal box on drivers side near brake fluid reservoir)....on this wiring bundled together which contains at least 100 wires, there should be a metal bracket which bolts (10 mm bolt)directly onto the engine. This is the ground connection, and the bolt should have a clean contact and bolted tightly on their otherwise it throws the computer off when the car hits a bump or stops.
Check this item first; hopefully it solves your issue.
Then it could be a burnt fuse powering up ur throttle body which is no more controlled by a cable, but a fully electronically controlled throttle.It is suggested to get an engine scan before proceeding, to ensure you are on the right track to a correct repair.Also could be the fuel pump, they tend to be a big problem on these cars. Another possibility is the EGR valve and can be fixed by anyone. It involves disconnecting the battery, remove electrical connection, and removing 2 screws and cleaning the surface area well and replacing it as well as the gasket.Also -APP/throttle pos. sensor needs calibration/replacement, -air idle control needs replacing, -throttle body needs replacement and even the computer needs replacement in this kind of issue.
These are all the probabilities and many more but first you should get your computer scanned from the local auto shop for any hidden codes which will make it easy troubleshoot your issue.

Please get back to us if you have further query or else please accept this "particular" solution.

Thanks for contacting fixya.com

SOURCE: 2001 Rodeo rough idle in drive, and sometimes on the highway

Check the overdrive accumulator cover on the transmission for any leaks. This can cause some rough idle situations and minor slipping but if caught early enough isn't bad to fix.

SOURCE: 1995-96 Isuzu Rodeo transmission swapable?

No they are not compatible. They changed the crank between 95 and 96. I have a 96 that needed an engine swap and the dealer that I bought it from was paying for the engine, he bought a 95 engine and after a month of trying the mechanic said no way no how, the crank between the two is different.

Do you know the OBDII codes? I just had to replace my Mass Air Flow sensor, it seems to have fixed my problems. But check the error codes.

What makes the reduced power light come on?


the "brain" of the car has detected a problem and is reducing the power available (limp home mode), get it to a garage and have them scan the odb2 data (or get a odb2 scanner and do it yourself. it will provide a fault code) the fault code will tell why it went to reduced power mode (limp home)

    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?
