Hey guys so I have this problem of whenever I drive my 2002 C5 vette it Dosent go over 2k rpm and whenever I try to get on it and hit the gas it throws it into reduced engine mode/Service traction control system , I just want your guy’s opinion on what it could be because I had a couple of guys check it out and they can’t really figure it out because the codes aren’t straight forward or at least they don’t look like it , these are the codes I’m getting , I already tried clearing them because they are history codes but they keep coming back also another detail that may help is one time the windows didn’t wanna go up after driving which leads me to believe that it could be something electrical or a ground wire , this is just assumptions tho I’m not a mechanic so I’m just guessing at this point

If these guys that are looking at your car are just “grease monkeys” I highly doubt they can diagnose this…are they using Service Information to read what sets the 2 current DTC’s which are giving you the Reduced Engine Power ??…they are both related to the APP sensor which is a simple potentiometer…find an auto electric shop in your area…these DTC’s are as straight forward as can be…it’s either a bad APP sensor, a wiring issue, or bad TAC module.

 

thanks for the advice man I’ll definitely take it to a electric shop !

 

Most of these guys can barely diagnose a light bulb circuit !!

 

First, and easiest thing, I would do is get the battery tested, a proper load test, not just voltage.
All the electronics on cars these days are super sensitive to battery power.

 

Moved to C5 Tech for more advice.
