Possible fault on Yaris 1NR-FE engine

[thetut]

Lars,

I noticed a few weeks ago that my Yaris would only start if I held the key in the start position when it was cold. The cranking also felt slower than usual.

I changed the battery and now it functions as designed.

Your battery may be getting weak.

Hi thetut,

Good point. Was your start/stop not working also before you switched your battery?

When I stop at traffic lights or whatever the indicator "ECO OFF" simply turns on and it doesn't shut off the engine (on low temps, like I mentioned). I guess it can make sense that it is a battery problem as batteries "lose juice" when cold, I guess?

Thanks!

Hi Lars,

I don't have the ECO function so I guess we are talking about separate problems. I thought you were talking about the feature that allows the starter to continue to crank the engine without holding the key in the start position.

I would still have your battery tested if I were you.

Cold weather and batteries cause strange problems.

Hi Tut!

Oh interesting... I would have assumed that all 1NR-FE would have the ECO thingy... so maybe it is normal that on low temps ECO doesn't kick in?

Maybe I'll open a new thread for that... but I'm not really worried, I can ask at the next inspection.

Thanks!
