Hey guys. So....

On my way home, im doing about 60 mph, go to shift my 07 ss/sc from 4th gear into 5th, and I missed 5th gear, slammed my gas pedal apparently, and yeah slammed the Red line.

Instantly "Reduced Engine Power" comes on and from this point on, the car does not start

Did i blow up my throttle? lol


I have a SnapOn code scanner...it shows these codes:


P0116: Coolant Temperature Curcuit Out Of Range
P0111: Intake Air Temperature Curcuit Out of Range
P0443: EVAP Purge Control Curcuit Fault
P0532 A/C Pressure Sensor Circuit Signal Low
P1516: Electronic Throttle Mod VS Throttle Position Performance
P2119: Throttle Closed Position Performance


I know it has to do with the last 2 codes i listed. I know with only the codes its hard to tell EXACTLY what it could be....but im hoping someone can imagine what would have broke after me going to shift gear(a bit violently lol) and missing 5th and just slamming the gas pedal in Neutral basically.

ANY HELP IS SUPER APPRECIATED!!!!

 

Was your check engine light on or did you have any of these codes tripped before you revved it?

Did you look under the hood for loose wires? I wouldn't think revving the engine should cause you to brake something.

 

Yes my check engine light was on prior to it happening. I know they were all there besides the A/C one...which i found a broken sensor...

and I agree i dont see how i could have messed up a wire by slamming the gas...but remember from when it happened...i was just shifting into 5th and i may have slammed the gas pedal i dont know....but my mechanic at my work also said it sounds like a wire problem...but i feel like i blew up my throttle by slamming the gas or something..(im no mechanic obviously XD )

but yeah...right when i apparently slammed my gas pedal in neutral and tried to get her into 5th gear...RIGHT AWAY...car dies. pull over. doesnt crank or start. if i wait like 30 seconds between trying to start it, she will crank now. but she cranks for 30 seconds now and automatically stops and says the "Reduced Engine Power" still. Turn it off, turn it back on and it will not crank unless i wait approx. 30-45 seconds

 

oh and the last 2 codes were not there...the P1516 and P2119 are new

 

Edit; just pulled negative on battery, pulled the computer out, and moved around wires for 15 minutes. Put it all back together, and still only cranks.

 

Are you still getting the coolant and intake temp sensor circuit codes? That makes me think you have a shorted/open in the 5v reference supply from the PCM. What that has to do with a neutral rev I don't know, but multiple circuit codes on unrelated sensors can't be them all failing at once.

Try swapping out the TB first though, if it's shorted internally it could be grounding one of the TPS ref voltage inputs. There's no code for that though so I don't know how sure i'd be that it will change anything.

 

This. It has to be something that would affect all of that. Wiring is most likely.
