Question about 2009 Toyota Yaris

1 Answer

The engine was running and then it suddenly stopped loosing all the power. I have the same problem with a Toyota Yaris. I have cleaned the MAF sensor a couple of times which SEEMS to help for a short time, although I am not quite sure as it has been happening intermittently for over a year now. It seems to happen more when going slowly but, again, that might only be coincidental. Would appreciate if anyone could give a definite solution as I don`t wish to pay out over £200.00 only to find out I still have the problem.

In order to know what is causing this problem you need to test the maf sensor voltage, and if your car is that new only the dealer should be handing the 2009, they are the only ones who will have information on that new of car. Maf sensor could cause the car not to run but you would need to test other components as well. For instance the fuel pump and fuel pump pressure. Since it is a condition that’s intermittent it will be much harder to figure out. So they can give you an estimate to trouble shoot the problem but they can only test, and if it does not fail the test then you have to test the next thing in line with your problem. You could have a bad vapor recovery purge switch. If it has been missing for a while it could contaminate the catalytic converter and plug it as well, this to can be tested but if it runs bad occasionally you could even have some bad gas. Or you could have a short in the system and a mechanic can’t wave a stick over it and say it’s fixed. He will have to run diagnostic tests. He can’t work for free so he could give you a price for what he would charge to do What I suggested before he would replace parts. Hope this helps

Yellow/Orange engine light on the dashboard what is the problem?T

Toyota Yaris engine warning light - this light will stay illuminated if there is a malfunction within the engine after start up - we would advise you to use the Toyota i905 iCarsoft kit to diagnose the engine problem, the kit will also clear the codes & reset the dashboard light. You might need to replace your MAF sensor because of this warning light, if so you should visit for a replacement.

Location of the EGR valve for yaris year 2008 as engine is misfiring and scanner indicate EGR faulty. Is it possible and if there is one

The egr valve should be located on or very near the inlet manifold it usually has a stainless steel pipe running towards it these can be cleaned and that's where the fault may lie with it as they clog up and stop working usually if the egr valve is flogged up you may need to check the inlet manifold as this gets worse than the egr aswell at the same time

Yaris completely loses power and 'pops' when accelerating

Only going with Toyota because they see many Yaris problems, it may be the problem. I have several bits of advice. Find out if the O2 sensor is classified as a Federal Pollution Warranty device. The Federal government requires a 7 Year and I believe 70,000 to 100,000 Mile Warranty on parts affecting the Emissions requirements.

This means a FREE repair. Also go to and toggle through the menu and select your car to find out about Recalls and TSB's. There may be more info about other things wrong on your car.

I hope my solution is helpful, please rate my response.

Take your car to your local autoparts store and have them pull the codes - this is free at most stores. Post the codes when you're done. This can be caused by anything - even as simple as not tightening your gas cap (you should hear the clicks - it doesn't damage the cap).
