2016 Taco High Low Idle

Hey all, I’m new to the Tacoma World Forum and brand new to Toyota. Was a Chevy guy turned Ford guy, until I bought my first Tacoma. I fell in love with the design and interior. But recently I noticed after the truck idles for a short time, it’s start to high low idle. Is this a Tacoma design flaw or an issue with something? Any help and guidance would be helpful.

 

What do you mean high low idle.

 

When the truck is in park it revs up and goes back to normal idle.

 

Well it could be a number of things, AC pump, injector cleaning, it doesn’t sound out of the ordinary.

 

Thanks

 

Its most likely because you a/c compressor is kicking on is my thought

 

I’ll give it a look. Maybe something simple. Hopefully

 

Mine does this, I wouldn't worry too much. The AC runs automatically when its on defrost or the foot/defrost combination. And if you turn the wheel the PS pump works/raises idle. I had a similar issue with my K&N filter and MAF sensor, and I fixed it by cleaning the MAF with contact cleaner.

 

When my truck does it it has a click right before it idles up or down

 

Mine has been doing it for 4 years

 

I just tested it out. As soon as I heard the click the idle came up. As that happened I shut the heat off and it returned to normal idle. I did it several times to make sure and that definitely is the culprit. Must be some type of design flaw. Glad it’s not a big issue. Thank you for the guidance.

 

No problemo

 

Not a design flaw.
