Marshamellow Posted March 26, 2017 Share Posted March 26, 2017 Hi My Toyota Yaris has got a slight problem with the engine light , it drives perfect but the engine light refuses to go off, I've checked maf sensor that's ok, changed oil and oil filter, air filter, brakes, all ok,pistons firing on all cylinders, I am at a loss as to what else to check so I'm hoping someone on here may be able to give me some tips, money is short so I can't get a diagnostic at the moment so any idea's would be much appreciated Link to comment Share on other sites More sharing options...

alchresearch Posted March 27, 2017 Share Posted March 27, 2017 (edited) http://www.outilsobdfacile.com/location-plug-connector-obd/Toyota-Yaris Needs a diagnostic though otherwise you'll constantly throw money at the problem and be replacing what could be OK parts. It might drive fine, but the light is telling you something is wrong and could be causing unseen damage or cause premature wear. A faulty MAF for example could make the car run richer, unburnt fuel could soot up other sensors and give you a bigger repair bill further down the line.

PeteMorris Posted March 27, 2017 Share Posted March 27, 2017 I have to say, I have a big 'downer' on engine management lights and others suddenly illuminating. In every scenario I've come across, it's not anything to do with the problem indicated, but to do with the sensor itself or wiring to it. But that's just 'my' experience.

Buying code readers is a bit of a minefield. I ended up buying two because the first one I bought didn't read the 'codes' I needed. Link to comment Share on other sites More sharing options...
