- After I cleaned the throttle body on our 2007 Jeep Wrangler JK I started getting the Lightning Bolt Symbol so I am doing a Throttle Body Relearn.

Good stuff my guy. That tool awesome.
Watching this video brought back memories of a stressful time. I had a high mileage Toyota that started to idle too low. No codes. I had never cleaned the throttle body, so I did using throttle body cleaner, an old toothbrush, and a rag. After I finished I immediately got a code for throttle body performance on my D8BT. I pulled it apart again with the sinking feeling that I just did something to destroy a working throttle body. It turned out there was a single thread from the rag I used that was caught between the valve and the throttle body wall near the pivot. That is all it took to get a check engine light.
I had to replace throttle body, gas pedal. That made that light come on occasionally. Finally fixed it by replacing the air intake temp sensor. I have 491 k miles on those parts.
Nicely done!
Nice fix! Some scanners it’s ETC and some is ETS. Great job 👍🏻
Have had to do that a few times 👍🏻👊🏻
I'm having this same issue, but unfortunately mine is worse. It's on a 2010 Dodge Nitro. 3.7L .. I'm getting the lightning bolt on the dash, but NO codes; and it will go into limp mode. But if I just cycle the key, it all resets and goes away again. So I cleaned the throttle body to make sure-- it was quite clean, being that it's only a couple years old since the last one broke some internal gears... So I was thinking it's the accelerator pedal then. As you know, there are two potentiometers inside the accel pedal.. So I graphed them both: APP 2 is having a pulsing drop out every 3 or 4 seconds. sometimes 7 to 10 seconds.. but usually shorter intervals. It just drops out over and over.. Whether my pedal is half throttle or held to the floor, or even untouched -- I can see it drop out in every position......... So I disconnected and tossed the accel pedal aside completely: and shorted my accel wires to the signal wire (through a test light) at the connector, down at the pedal--- so that it raises on the scan tool- simulating holding full throttle: just the same as it does when I step on the pedal in normal use. and APP 2 STILL drops out in random pulses?? Even after bypassing the accel pedal completely..
So I think I may have a bad computer, unfortunately. I don't think it's a short in the wire, because it drops out in a very consistent and clean pulse. It's not like it drops and stays off for a random amount of time like a short would do. it always turns off and right back on in a very clean and predictable down pulse. just drops out............. I guess I can bring in an independent 5v reference and short it to the signal wire and see if it's the power side dropping out-- or if it's just the signal wire shorting internally and dropping out?? It's not a fun problem though. Like I said, it doesn't even trip a code-- yet it happens often enough that I can't even complete a throttle relearn-- because that drop out happens while you're waiting those few seconds during the relearn.
I wish I was near you-- I'd buzz over there and let you do a video on it.. but I live in Oklahoma. :) ... I'm hoping it was only happening on those coldest days, and now if I go check it, the problem will be gone; because it was well below freezing when I messed with it; fingers crossed.
What part of Oklahoma?

What was the program you used I'm having the same issue with my 08 jeep wrangler Rubicon I cleaned the throttle body today as my jeep would not start but I had full power.
I used the CRP919EBT scan tool.

so did the throttle body relearn get rid of the lightning bolt error?
It did for about a month then it came back and I did another relearn and after about 2 months it came back so I installed a new aluminum throttle body and that fixed it for good.
