360 Which scanner can reset throttle body adaptation values?

Not sure we are talking the same thing ..but isn't disconnecting battery ..then idling till temp and then idling for 10 mins without touching the car with no electric draw re-train the TB

I thought disconnecting the battery reset them.

Mitch - is there a function like that in the SD tool ?
Maybe someone has a Autel or OTO scanner - 919 or equivalent to try

Although there are alot of scanners out there - other than TEXA, SD, and autoenginuity, the remaining are copies of Launch or Autel

So if launch doesn't work .. you need to try the Autel family ( OTO is a knock off of Autel)

 

Of course the Leo as well ..missed that

Mitchell, this is the info from my 'Notes' on this matter. This info was put together from the various capable sources on this site (Trev, Rifledriver, Taz, Flash and the likes)

Resetting the Throttle Bodies: TBs needs to learn or relearn the resting point (fully closed) and end point (fully opened) sometimes after a battery goes dead or new TBs get installed. During the learn or relearn procedure you could actually hear them go through the cycle(s) which then gets stored in the volatile memory (not saved if battery goes flat!) when the key is removed.

Start with a healthy battery. Put key in position 2 with engine off. Once it says SYSTEM CHECK OK, press the accelerator pedal down to the floor, and hold it there for 5 seconds and then release slowly. Do this a couple of times and you'll be able to hear the throttle body opening and closing depending on your pedal angle. This procedure will rapidly accelerate the learning of the TPS (Throttle position sensors). After doing this 2 or 3 times then turn off and take the key out. Wait 4 or 5 seconds before putting key back in and going through normal drive cycles. This will tell the throttle bodies to re-calibrate. Wait 5 more seconds then try starting the car.


Other re-learning will happen when driving such as how well the coils and plugs in individual cylinders are operating, the ECU will sniff the exhaust via the O2 sensors and adapt (or trim fueling) and learn some more and eventually after all the learning is done. Time to complete depends on type of driving, etc. Normally after about half an hour of different driving it's done. You can be more scientific but it's ok to just drive slower during warm up and then do different speed roads, in my experience and it's still ok.

Here's hoping I didn't misunderstood their advice

 

I changed out TB's at least a dozen times in my car. I never went through any specific startup procedure, but I always did a reset with the main battery switch.

Sometimes I reset the throttle adaptations (with an Autel MS906), sometimes I didn't. I didn't see, hear, or sense any difference.

 

Yes, but obviously that's not the case with the OP. He's got Cels.

 

Every time you turn the key to on. It happens very fast but have a friend key it up and watch the throttle plates. You can hear it too.

Throttle self learns every time.

Besides, rich or lean is not a function of throttle. A host of other components control that, the throttle just controls intake air quantity. Other components control how much fuel is delivered. Throttle is not even in the equation.
