P0133 1999 Ford F150 -

Question

I have codes P0133 and P0135.  Do I get the same O2 sensor for both in my 99 5.4L F150?  Bosch 15717 seems to be the replacement sensor.

Answer 1

P0133 H02S circuit slow response Bank 1 Sensor 1

P0135 H02S circuit malfunction Bank 1 Sensor 1

The best way to find the replacement is with the VIN the 8th character will determine the part number for the 02 sensor replacement
