Check Engine Light And Trouble Codes

[markstahl]

I have a 1998 Camry V6 California Emissions and recently had the CEL come on. I borrowed a scantool from a local Autoparts shop and I got the codes P1130, P1135 and P1133. All are for the Air-Fuel Sensor, they are Toyota specific codes, so is this their way of saying the O2 sensor is bad? If not, anyone know what the air-fuel sensor is?

Thanks, Mark

Yep, it's the 02 sensor(s). Your Camry may have up to 3. 1 for each bank of cylinders in 1 before the catalytic converter. I would drive it until you see the fuel mileage degrade to the point of shelling out the considerable $$ to replace.
