Random “flash” of CE lite from TPS

Been 3weeks of searching/diagn/using newly bought scangauge2 (now I can report realtime data!!)

fixed
Thanks to prior threads/links posted by DM93/glamisman/TNshooter and superwhite
Big thanks to Thatt/cowgarf3 as well

soooo
Not flashing CE lite constant but on for 3 secs then off for 2mins then a 5 sec flash followed by a 2 sec blink

Taco would bog….zero throttle response when CE lite on…..the CE off everything normal

yall know me and codes…..I couldn’t read a code….no stored codes either
Broke down and took advice to buy scangauge. Set on TPS reading
Determined that tps reading would freeze for same amount of time as the CE flash
Bought (ugh P cannon FTL) OE TPS, installed and calibrated
Same issue

back to TW for more searching
One 2018 thread similar issue, dude found harness pigtail from TPS cracked/melted.
Started to take off harness to inspect. During this wrenching, Thatt advised make sure grounds good. Nothing obvious with harness and found some diagrams of the 3 grounds (2RZ). I found 2 looked good but removed/cleaned anyway
frustrated, thinking I’m going to have to do ECM pin out test went to bed.
Cowgarf3 motivated me after work today (and was 10 degrees cooler than yesterday)
Look WTH i found….

 

Please everyone “prior owners” work there!

could it be that easy????

new ground wire made

 

Installed

 

Then had to re-lace engine harness also corriosionX-d all pigtails

went for extra long test drive
SUCCESS

thanks again for everyone that posted (long ago in other threads)

funny
I’m 90% sure a shop would of installed a $550 throttle body and still wouldn’t of fixed
Turned out to be $2 in parts I had in my garage.
Cheers!
