Hello all,
Someone please help, and show me how to fix these issues?
My have had the check Engine light turn on for a while with these code below:
P1130: A/F sensor circuit range/performance malfunction (bank 1 sensor 1)
P1150: A/F sensor circuit range/performance malfunction (bank 2 sensor 1)
P0171: System too lean (bank 1) with the following freeze frame data below.
Fuel sys 1 = CL
Fuel sys 2 = CL
Calc load (%) = 47.8
ECT (deg F) = 174.2
STPT B1(%) = 19.5
LTPT B1(%) = 1.6
STPT B2(%) = 19.5
LTPT B2(%) = 3.1
Eng (RPM) = 1747
Veh speed (mph) = 24
IAT (deg F) = 100.4
So far, I replaced the Mass Air Flow sensor make by Denso 197-6020, and I bought it from Amazon for $76.00, but the check engine light still on. http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=maf%20sensor%202000%20lexus%20rx300
Also my car consumes too much gas, I got about 5-10 MPG city.
Thank you for your help.
