MIL and O2 Sensor Issue - Toyota Yaris Forums

rafhelp · 01-04-2018, 09:52 AM

I had an issue (which may or may not be related to the problem), I had empty tank (one bar flashing) I then filled in £10 petrol and came out petrol station to see the fule level bar was still flashing. I thought this has to be wrong.

After driving for a bit the bars went upto 2. Why is this.

The problem:
Was out driving on motorway and engine MIL light came on (yellow). Driving wise it does not seem much different. But maybe a little less responsive to gas pedal.

Hooked up machine and it showed up a code. 02 Sensor stuck / Rich Bank 1 Sensor 1

Can I try this.. erase the code with the machine and drive around for a bit, if the problem is real and not a false flag, the same light and code will present itself. Then I suppose its time for garage.

Is this a common issue and is it expensive to fix?

I read o2 sensors last about 60K miles and mine has more than that, could it be a case of it being worn out.
