CEL, REDUCE ENGINE POWER, possible TPS error?
My car is gay. I Just installed stage 2 injectors, pulley, and a tune from xskier874 (thanks man) Ever since I put the 3" pulley on and have hit moderate boost (5psi at the max) the engine cuts out and goes into reduced power mode. We scanned for codes and got CPS learn error. Any ideas? I'm calling the dealer tomorrow. It's drivable, just does't go into boost.
UPDATE: OK. Now the problem only occurs when I really floor it. It seems to happen in the upper RPM's (5000 and beyond). If I am cruising and hit boost it is fine. I reset it by unplugging both + and - terminals and touching them together, and by jiggling the connector around that sits under the TB. It clears the code, but it comes back and cuts power once the engine hits high RPMs (under boost) HELP!! I'm in levittown, NY right now and have a 3 hour drive home. I don't want to limp the car back like I did on the way down. Argh.. |
Yup takes like a minute with the Tech 2

So what do they do just plug it in and relearn it? It won't erase my tune I have on there will it?

Nope wont erase it.
So do you guys think this will help fix it? Well I let it sit for an hour. GO out and start it, no reduced power. BUT the CEL was on. I get to the end of my street and BAM reduced engine power kicks in :( THIS SUCKS! I can feel the extra power from my pulley tune and injectors, then its all taken away from me. :( Worst feeling in the world. |

Sweet. I'll have to get someone to relearn it tomorrow before my road trip. I drove 250 miles today with the car like this. Sucks so bad to drive a SS S/C in vacuum. :(

Usually does that computer needs to learn certain parameters from the cranks sensor and a few others.

Yeah like i said earlier it only takes a minute make sure the car is warmed up makes it a lot faster. What they have to do with the Tech2 is select the year then power train then engine type then special functions the CKP relearn rev your engine until it hits fuel cut-out then bam it is done.

Yeah. I'll inform them of that just in case they are retarded. I hope it fixes it though.. it SUCKS so bad to drive in reduced power mode :(

ALright. The code was code 315 crank position not learned I believe. We tried clearing it in HP Tuners but it kept popping right back up. :(

My buddy is going to do the relearn tomorrow at 1145. Hopefully that takes care of it and I can finally hit booooooost :) Thanks for your input/help btw man. Really appreciate it :) IMO this is how every thread on this forum should be. Helpful, friendly, and straight to the point. :lol:

did you remove the pcm for tuning

WTF. Got the crankshaft relearned, ran great. I was testing out some WOT, ran fine. I hit 7k and shifted to 3rd and BAM,.. reduced engine power again! WTF!
The Tech 2 was saying throttle position sensor.. i think the code was p0122. but would that make the car go into limp mode? Help! THis is so gay I have a 3 hour drive to long island soon :( |

I've been reading that it might need a CPS-relearn which can easily be done with a tech II scanner.. what do you guys think? I'll be back tomorrow night from Jersey if you're still around, just not til really late, I'll be in Warwick NY on sunday tuning another turbo converted cobalt. |
