Reduce power light

[KLJ]

Reduce power light and check engine light comes on then I can push gas pedal and I am lucky if I can go 10 mi. any one know what it might be replaced o2 sensor and throttle postion sensor because it threw out those codes but still does it .

First off, what year is your vehicle?
Second, you are lucky if you can go 10 mi. and what...?

If your lights dim it could be your alternator is on its last legs, but without more info it's hard to roubleshoot your problem.

He has a 2001 Rodeo (in his profile; thanks for filling it out!)
My best guess is this:
3. Check The Ground At The Alternator Bracket

Here is a link to some other idea's (I'm pretty sure this is an electical issue):

sorry its a 2001 Isuzu Rodeo, the reduce power light comes on then the check engine light then it slow down to a crawl even with the gas pedal all the way to the floor. But it doesnt quit running . Thanks

Could this also be a failed throttle by wire component? IIRC, someone on planetisuzu had similar symptoms & that's what it was, bad TBW.

Let Me Know What You Find Out If You Fix The Problem Mine Has Been Doing The Same Thing For About 2 Months Does Yours Surge Down The Road? I Have Been Checking Wires And Ground For A While But No Luck Yet I Have A 01 With V6

Yes, sometimes it does do that also it just started when I am braking sometimes really hard it just dies. But I am still trying to find the reduce power light problem checking the wires around the throttle. A guy on another site said it might be an idle speed control actuator he said it cost around 300 bucks just for the part I hope not.

I Had The Codes Read It Came Up With Like 6 Different Ones That Pretained To The Egr And Throttle Position Sensor I Replace Egr First At Around $100 Not The Problem I Replace The Tps At Like $150.00 No The Problem I Took It To A Mechanic That "guaranteed Diagnosis" $188.81 Later He Says It Is The Tps That I Had Replaced 2 Days Earlier He Said I Have 30 Years In The Business I Know What I Am Talking About. So I Ordered A New Tps At Another $150.00 Guess What I Wasn't The Problem Old One Was Sent Back For Testing And It Was Good! Mine Dies When I Park Alot The Reduced Power Light Comes On Usual When I Make Turns But Sometimes Just For The Heck Of It. I Am Not Sure If The Idle Sensor And Throttle Sensor Are The Same Thing But That Wasn't The Problem With Mine. I Have Been Talking To A Guy On This Site That Is An Isuzu Tech He Said These Years With This Motor Have Had A Lot Of Wiring Related Problems And We Are In The Process Of Going Through Them Now So Far With No Luck. Good Luck And Keep Me Updated Maybe We Have The Same Problem

Throttle postion sensor and the idle speed control actuator sensor arent the same . But I dont know where to start we have went thru some wires. Its just expensive and time consuming . Let me know about yours too maybe we will figure it out.

Hello Guys Isuzu dead on the side of the road with the problem it was still having after tons of searching new techincan says it is the motor on the throttle body , 525 for the part and 150 for labor , 50 for tow. Hope this helps somebody with the same trouble.
