Twice in the last few weeks my Ridgeline lost nearly all response from the throttle. This was accompanied by a check engine light. The first time it was a P2176. Yesterday, I received a P2101 and P2176.

The first time this happened, about a week ago I turned the truck off and then back on again and the issue was more or less resolved. I reset the check engine light and I thought the issue was a fluke. Yesterday, this issue occurred about 5 miles from home. However this time resetting the check engine light and restarting did nothing to resolve the matter.

From what I can tell from what I've read, this is an issue with the throttle body unit. I purchased a used one that should be here any day. I will see if installing a good used one will resolve the issue. If not, I'll try a reman unit.

Are there serviceable parts on these throttle bodies? Is it a matter of cleaning, or did a mechanical or electrical component likely fail?

Has anyone experienced this? Did replacing the throttle body unit resolve this? What else was needed?

Info, in case this is relevant

Thanks @GhostYK1. I should have started it up first, but I did spray the throttle plate and some of the inside of the throttle body. I was able to get pedal action back and I was able to reset the code without it coming right back. It could be because it sat overnight and had time to cool. The three times this has happened were when it was hot 90 F+ and in the afternoon after some local driving.

I have a used spare throttle body on order. I may just clean that up and swap it out if/when this happens agian.
