Hi,
I'm looking for the MAF sensor on my '99 Yaris.
About two weeks ago when driving, the CEL came on and
stayed on for the rest of the trip. Connected my ODBII scanner when i got home and it returned error code "P0171 - Powertrain - System too lean (Bank 1)".
The engine is running normal, if it wasn't for the CEL, i woudn't have noticed any problems.
So i found that a dirty/broken MAF sensor could be the problem.
A new sensor cost around €280,- so i rather try cleaning it first then buy a new one.
There are sensors on both sides of the air filter box, does someone know which is the MAF sensor?
