cat sensor fuse?
Still patiently waiting for my cat sensor to reset so I can get a p1111 reading from the OBD connector. I have done all the driving rituals (55mph for half hour etc) and it is the only sensor that wont reset. Does anyone know is there a fuse between the cat sensor and OBD port?
Thanks

Try this procedure????
HEATED OXYGEN SENSORS MONITOR DRIVE CYCLE
Upstream (Universal) oxygen sensors:
1 Engine OFF; cooling fans inoperative >20 seconds.
2 Start engine and bring to normal operating temperature >82 °C (180 °F).
3 Drive the vehicle between 3000 – 4000 rpm in 3rd gear at a steady speed. Lift foot completely off accelerator and coast to a stop within 30 seconds. Do not touch accelerator pedal for 4 seconds after coming to a stop.
4 Repeat Step 3.
5 Idle engine for 11 minutes.
Downstream oxygen sensors:
1 Start engine and bring to normal operating temperature >82 °C (180 °F).
2 Drive the vehicle steadily between 48 – 97 km/h (30 – 60 mph) for 10 minutes.
3 Drive the vehicle above 3000 rpm in 3rd gear at a steady speed. Lift foot completely off accelerator and coast for 30 seconds.
Oxygen sensor heaters:
1 Start engine and bring to normal operating temperature >82 °C (180 °F).
2 Idle engine for 3 minutes.
ADAPTIVE FUEL MONITOR DRIVE CYCLE
1 Start engine and bring to normal operating temperature >82 °C (180 °F).
2 Idle for a minimum of 10 minutes.
CATALYST EFFICIENCY MONITOR DRIVE CYCLE
1 Start engine and bring to normal operating temperature >75 °C (167 °F).
2 With the gear selector in Park or Neutral, hold the engine speed at 2500 rpm for 5 minutes.
3 Drive vehicle ensuring that vehicle speed exceeds 15 km/h (10 mph) and the engine speed exceeds 1500 rpm.
4 Stop the vehicle and check for any temporary DTCs using WDS.
Good Luck!!
