Replace Throttle Position Sensor, 2007 - 2015 Chevy Silverado, Avalanche, P0121

[@alanswett3221]

I just finished fixing mt 2010 tahoe. Took your advice. The whole unit came off. Got it all back together. Works fine. It does idle high then goes down where it's supposed to be. Thanks very much. Al from Maine

Mine just started messing up last week with this cold weather we're having up here

[@alanswett3221]

I'm glad I watched this video after seeing one other or two this one was much better and with more information easier to see what's going Little details I would have missed like the gaskets and things all that good stuff.

[@bigcartoonyIIV]

im glad i watched this. This seems easy. My silverado has been dragging, and seems like its taking off in 2nd gear very sluggish.

Why does the butterfly have to be in the all the way open position to line up the new sensor? Wouldn't just a hair of a turn line up the pin?

[@RustBucketRepair]

That's the way the instructions say to do it. Probably for calibration.

[@powleyinlakecnty]

@canamsledder scantool completely necessary for idle relearn? Just don't want to destroy trans while shifting at high rpm's just hoping idle comes back down by itself

[@RustBucketRepair]

Mine didn't idle to high, it settled down in a few days.

[@powleyinlakecnty]

@canamsledder it's idling at like 2400 rpm. Won't come back down. Maybe sensor is crap. Putting old one back on. Throttle body was gross, super clean now.

[@hehehe1515able]

Isn't opening the butterfly what damages it in the first place tho?

[@earllane9566]

Did it ever idle down

[@RustBucketRepair]

Yes it did. Took a couple days!

[@powleyinlakecnty]

Mine did not

[@earllane9566]

Mine didn't not either

I just replaced the throttle body sensor and mine will I don't find for just a few minutes then if I burp the throttle it reads up to 3,000 or 3,500 anybody know how to fix this?

[@Angel26839]

@@RcOutreachdid you ever get it fixed? How long did it tale

[@GreenWave18]

Just replaced both the throttle body and sensor on my 2013 suburban. I've driven it a few times now, and whenever I go over 55 mph, then put the truck in park, the RPM's rev all the way up to 3K. When it does this, I immediately shut off the engine. Any suggestions on how to get the idle back to normal? I'm wondering if there is either a special start-up procedure or some sort of built-in firewall inside the computer, recognizing it as a new, non-GM part.

[@Angel26839]

Did it ever fix its self?? I’m having this problem

[@charliebrown8480]

Thx that worked

[@matthewbarbosa7728]

There was nothing wrong with that sensor. The problem was the dirty throttle body. The ECU detected that it had to open the throttle further in order to maintain the same RPM. This is due to the build up in the throttle body, that thing was filthy.

Why the gloves?

[@RustBucketRepair]

@michaelglenn1228 Because I have an office job during the week. Just easier to keep clean.

[@michaelglenn1228]

@@RustBucketRepair Thanks for the reply...Now i understand why the gloves !

Maybe a cleaning was all it needed.

[@ritocastillo8958]
