My 2016 V6 Tacoma doesn't seem to be idling properly. Two things have me concerned - 1. The RPMs go up and down slightly when the A/C is on (around 500 - 1000).
2. When I turn the A/C off, it doesn't do it, but it seems that it could be idling too low (around 500 RPM).
No codes or anything, and it drives great - it's just annoying and I don't want the issue getting worse if I can fix it now. I've never owned a mid-size truck, so I'm wondering if maybe I'm just not used to it? I had a 2017 Honda Civic before this truck, and a 2010 F-150 V8 before that. I think I remember the Civic idling like the Tacoma is, but it was more subtle. And I don't remember the F-150 doing it at all.
Anyway, any suggestions/thoughts would be greatly appreciated. Thanks!
Load test the battery and alternator. You may have a weak alternator. If they checked out, the AC compressor might be faulty.
Will do - thanks! Didn’t think of those, but the AC compressor did cross my mind. Is idling around 500RPM normal? Or should it be higher, around 1000, constantly?
@Doc has your answer.
It should be around 750 rpm and a little higher with the AC on.
Thanks guys - appreciate the info, as always!
