I just began having the same exact issue about two weeks ago, where I found myself stranded on the side of the road at an idle with no throttle response. The VSC , TRAC, and CEL all turned on at the moment I lost throttle. I cycled the ignition once by shutting off and starting the car, and it seemed to fix the problem. After getting home and doing a few test drives, the same throttle cut-out issue was happening under acceleration and load.

After some quick searching I decided to order a new 4 prong TPS from Aisan part#(89452-35030). This is the cheapest way around changing the TPS without changing the whole Throttle Body on a 2001-2002.

All of my check engine lights went off, and the issue seemed to be fixed for about a week, until it came back this evening on the drive home.

My only other idea for this very specific issue is a throttle body replacement, possibly a used one off of a junked 2001 SR5.

I am getting a P1120 code which my Blue Driver says: Throttle/Pedal Position Sensor/ Coolant Flow control ValvePosition Sensor Circuit
Does this mean I should look at the PPS now? Not sure If I could even get one of those

Any updates at all since doing it in 2021 would be GREATLY appreciated!

thanks!!
