Just got back from having AutoZone rescan. Today's codes are P0133 (O2 slow response, B1 S1), P0135 (O2 heater condition, B1 S1), P0401 (EGR). FYI, I replaced my EGR and tube to exhaust, my vacuum solenoid, DPFE, and both rubber vac hoses 14,000 miles ago. These hoses are clear and not leaking. The note with P0135 says the PCM recognizes a sensor heater faliure and to check the circuit fuse, but I have no idea where that is.
I just bought a B1 S1 O2 sensor and new DPFE sensor. Before I put them on do you have any ideas I should try first?
