Lexus RX300 Check Engine Light and Lack of Power Due to Failed Mass Air Flow Sensor
The Check Engine Light may illuminate because the mass air flow sensor sends incorrect information to the engine control computer. This can cause a loss of power on acceleration. A failed mass air flow sensor will require replacement.
I have to replace MAF sensor and O2 sensor - Visitor
obd codes P0171 system too lean bank 1 P0174 system too lean bank 2 P1150 AF Ratio range performance bank 2 sensor 1. first cleaned MAF meter at air box with no success. checked air filter, looks new. checked all vaccum hoses for leaks, ok. replaced MAF, reset CEL by pulling EFI fuse under hood, road tested under malfunction scenario, good to go! no CEL. will verify with more mileage to be totally sure. - mjp1031
This is actually the second time I had the problem. The last time was about 5 years ago. The mechanic replaced the air flow sensor and other minor tweaks as well. Cost was roughly $575 each time. - Visitor
