Engine Performance problem
1999 Lexus ES 300 6 cyl Front Wheel Drive Automatic 275000 miles
This car gave a code of P1133 sensor 1 bank 1.
The Mechanic says this is the o2 sensor-located at the
front exhaust manifold.
However, othrs have described P1133 as the fuel air
sensor located neatr the catalytic converter.
I would like to have the correct one replaces, since there is a difference (as I understand) between the fuel air and o2 sensor.
Please help what is the correct answer?
