2017 Chevy Silverado P00C7

[Zack Lantto]

Hey y'all! I had code P00C7 pop up. I replaced the MAP Sensor. Check Engine light turned off but, Code P00C7 is stored, I'm having a rough idle, and hesitation in acceleration. I just had the throttle body assembly replaced as well. Any help is appreciated! Thanks!

Have you tried to do a reset on tge throttle body?

[Zack Lantto]

Reset was already done

I'd try to do it again if it were me. Classic symptoms.....not saying it is ...but...several YouTube videos on it. Try simple stuff 1st.

[Zack Lantto]

I'll look into it. It also fails an emissions test.

2017 Silverado...what?  1500?  2500?  3500?  4.3, 5.3, 6.2?  6.0 in an HD?  6.6 Duramax in an HD?

 

Are there any other codes besides that one?

2017 Silverado 1500 LTZ Z71 5.3, 6L80.

 

No other codes stored.

The code means an issue between the Baro data and the MAP data , I'd check for an air leak in the intake system, possibly giving false data from the MAF. I believe the ECM pulls baro data from the map sensor.

[Zack Lantto]

It shouldn't have an intake leak cause the top end was just redone with new gaskets and seals.

[rav3]

Shouldn't is the key word. But maybe something wasn't done correctly? 

[Zack Lantto]

It's possible. The dealer I've been taking it to seems to give me my truck back with a new problem everytime. It's been going to the dealer so I can maintain my warranty. Otherwise I'd do all the repairs myself.

I have most of my engine and transmission service done at my local dealer. If something goes wrong, I'll have someone to blame.
Everything else, I do myself.

[Zack Lantto]

Well, I've done both the MAP and MAF Sensors and still have the same issue. Any other ideas are appreciated.
