Was driving my commute to work and there's a couple of pretty large bumps going about 75 mph.

After a bump Service engine soon light, Asc Light then later when it hit Limp mode EML light came on.

Have done a ton of research on this issue some say its throttle body others say its battery and even fewer say its actually the Wiring harness.

My question is has anyone else had this issue? Will the battery really cause all these issues? Is there a "TB Wiring harness" so i'm not replacing the entire wiring harness?

Any help would be most appreciated.

 

Till you get the code pulled, it is JUST SPECULATION.
get the code ....
Before then speculation is just that...
The code will lead you down the path on where too look...
Could be 5¢ rubber hose, or a loose wire...

 

Codes pulled p1226 p1125

 

P1226 Throttle Malfunction (Flap Malfunction)
P1125 Throttle Position Sensor A and B Range/Performance Small Error

This tells me that likely the drive-by-wire can't read the pots to close the feedback loop. You'll want to trace the TB harness back for abrasion and remove/clean the connector, to eliminate the easy stuff.
