P1400 Code?

[MrDJ]

Earlier today my TB threw a P1400 code. (Went to AutoZone to have it pulled)

Definition:
- Cold start reduction control system.

Possible Cause:
- Lower than expected cold idle speed.

Has anybody had this error? I have googled it and I do not know much about the engine so I am lost.

Thanks!

My truck was giving this error code (P1400) along with P0105 & P0506 not too long ago. I was able to solve all 3 by cleaning the throttle body.

Alright. Looks like I'll be doing that this weekend...

.....so how'd it go?

 

[MrDJ]

It went very well. Took about 45 minutes in the parking lot behind my dorm. lol A cheap and easy fix!

My 2007 Envoy turned on its check Engine light last night. Runs fine, luckily.
A friend checked the code- P1400.
So I'll be cleaning my throttle body this weekend too.

(p.s. Fuel sender seems to have gone bad again! I changed it last year
and it was fine until I filled up a couple of months ago- back to using the odometer.)
Probably not connected with the P1400 though.

Guaranteed not related.

Did it today. Like others have said- it was easy and the engine runs smoother (audibly and by feel). It used to have a 'raspy' sound and feel recently but now accelerates very smoothly.
A bonus is that while the battery was disconnnected the memory was lost, so the error code has cleared on its own. I don't need to borrow my friwend's checker to reset the code.

Thanks to the original authors of write ups on Trailvoy and the new ones in GMTNation.

By the way, Roadie, do you know your latest picture on this site looks a bit like "Sheldon Cooper" on Big Bang Theory"?

Hmmmmm, never heard that before.

That's actually a picture of me in college in 1972. I'm a bit pauncher today.

Really, It *is* Sheldon Cooper. I act like him, but don't look a bit like him. Besides, he's gay and I'm happily married for 39 years.
