Check Engine Light (air filter) - Toyota Yaris Forums

Likesavinggas · 06-15-2025, 09:38 AM

Ok, one last question before I perform the MAP cleaning. I ordered a can of CRC MAP Sensor Cleaner and have reviewed the instructions (also have viewed several utubes on how to do it). On the can it says "Do Not use on a vehicle with a Karman Vortex air flow sensor e.g. on some 2006 and older Toyotas" I would assume that my 2007 Yaris is ok?, but would like an expert here to confirm that my Yaris does not use a Karman Vortex air flow sensor. Thanks for your guidance on this.

Also, in a couple of those youtubes the mechanic would keep the engine running while unplugging the MAP sensor. They did this to show that if the engine stopped running then the MAP sensor was working as it should (though it still may need cleaning), but if the engine kept running then the MAP sensor was defective. Would you recommend this step?
