Re: P0133 02 Sensor and P1406 Emissions Controller Codes
P0133 Heated O2 Sensor Circuit Slow Response (Bank 1, Sensor 1)
the front O2 sensor needs replaced, most likey it is covered in carbon build-up
for the P1406, i'm not sure, i can't find the exact code, but take care of P0133 first and see if it comes back.
