ANOTHER reduced engine power incident. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

well, i resolved the issue of my throttle postion sensor from last week.

NOW... i turned off stabil trak. Floored the car from a dead stop. got a little wheel hop. "Service stabil trak" message appeared ...then back to reduced engine power. so i limped it back home on 4 cylinders and cleared the code. it comes back anytime i hammer on the accelerator. the car rolls fine. did not hear or see anything broken other than the codes and messages and reducing my power. any takers on this one?
thanks.

NipTuckTaxi · 10-14-2011, 09:30 PM

the new code is P0651.

Had that issue a couple times ,took the car to the dealer and bam , no more crap like that ,,,,,,,black wood

sounds like the throttle body is opening too far, the computer has to relearn where the max value is. not sure how to fix that. maybe just time

NipTuckTaxi · 10-15-2011, 06:03 PM

PCM voltage out of tolerance condition oon the 5-volt reference circuit.

all my connections are tight. no burns, kinks or marks.

any idea what may be happening?

Parag · 10-15-2011, 07:12 PM

P0651 Sensor Reference Voltage B Circuit/Open

looks like time for a ported throttle body

NipTuckTaxi · 10-15-2011, 07:54 PM

I just installed one a few hours prior to all this. First. Time wot and bam. I got stabiltrak service message and reduced engine power. I can get 8cylinders back as long as I don't get aggressive. If I do then its back to reduced power.

Take apart your wiring harness on the throttle body and take a close look to make sure one of your male pins is not bent. Also check any grounds that may have loosened.

Is this an EFI Live tune,Just wondering

NipTuckTaxi · 10-16-2011, 04:43 AM

i have inspected all of the grounds and connections and nothing is out of the ordinary.
im not sure what an EFI live tune is .

Bay Area SS · 10-16-2011, 10:26 AM

same exact thing happened to me. My headers burned the wiring harness for the 02 extensions and it was fryin fuses. thank god I was literally pullin into my dyno shop when this happened. He had to rewire some stuff. . .

LSX-80MM · 10-16-2011, 10:29 AM

It's a Tuning Software like hpTuners...You need to find a good tuner,and they are PRICELESS.Good luck with your problem.....

NipTuckTaxi · 10-20-2011, 04:05 AM

I still cant find anything out of the ordinary with the naked eye.
Im am kind of reluctant to send it to the dealership.
Can anyone recommend a good electronics tech/mechanic for this type of issue in the southern US?
