Check engine light when it's warm

FirstFlight · May 21, 2012

It's funny you mention that. I know for sure that my engine is warm and the battery pack is not hot but yet it won't stop idling sometimes. I use the EV button to shut it down sometimes.

I got it now. I'll give this a shot today and I'll report back with what I see.

I don't have a scangauge and can't afford one right now so I thought maybe posting here would help.

Last year my check engine light came on a couple of times at the end of the summer but it went away and I can't remember how. Today was the warmest day of the year so far for us and my check engine light came on again. It seems to happens when it's warm, I'm accelerating and I think the A/C is on but I can't be 100% sure about that.

I popped open the hood and looked around but I didn't see any issues. All of my fluids were at the correct level and my engine wasn't hotter than it should be. I believe there is a 2 MPG drop but I've only been through 1/2 of the tank so I'm not sure about that.

Without having a scangauge, are there any other cheap alternatives to finding out what code is logged? I've heard that Toyota charges something like $80 to find out.

Any other ideas that could help me?
