Hey there. I bought a 2010 Yaris second-hand this fall from its original owner. It has about 190,000 miles on it.
About a week after a bought it, the check-engine and ABS lights came on, simultaneously. The first mechanic thought it was an ABS-sensor issue, replaced the ABS sensors, and then reset the warning lights. A month or so later, the warning lights came back on.
I drove it like this for a while (just a little tight on money), until the transmission appeared to slip when switching gears (accelerating uphill, it’s an automatic). A few weeks ago, I took it to a new mechanic, who (I thought) correctly diagnosed it as a common issue with Yaris’s having to do with the exhaust filter and water circulating into the gas tank and engine. They replaced the filter – it’s the evaporative one, I think, on the exhaust; it was an $1100 repair (so not a normal air filter or anything) – and I was on my way.
This week, there are heavy rains, and, wouldn’t you know, both warning lights come back on again .
I’m curious – has anyone else dealt with and successfully resolved this problem? I’m a bit weary at this point of spending more and not quite sure what to do. I’ve trawled the Yaris forums and would genuinely appreciate any advice. I can go to Autozone later to have the engine codes pulled, if needed.
