P0120 Code Check Light Engine

1LEASYE · 05-19-2021, 09:57 AM

I got a check engine light (Code P0120) while at VIR this past weekend.

The throttle, all electronics HVAC etc. are totally fine as far as response and usage go and I cleared the code twice but it kept coming back.

Based off the research I have done with the code, it appears the ECU/Throttle Body has a miscommunication somewhere due to wires rubbing and/or a sensor giving a false reading, would this old thread I found on here be related to my error?
