Replacing O2 sensors

[mikefocke]

A P0130 can be
– Oxygen sensor
– Wiring harness
– DME control module

So the flow chart suggests first testing with another O2 sensor and if the problem persists, then checking the wiring.

Where can I find the flow charts? That would be a wonderful tool.

Update:

Got O2 sensors from Parts Train, crimped them onto the old connector for Bank 2 pre cat. Put them in and error code disappeared. Tested with Durametric and all seem ok for bank 2. Bank 1's P0130 persisted. So, swapped sensors from Bank 2 to bank 1 and vice versa. Bank 2's P0130 went away and Bank 1 was reporting P0150. So, replaced the one that was reporting error with new one from Partstrain and all is well. No error codes.

Looks like I can now get my darn inspection done. However, the "Ready Status" screen shows Fail for all (Cat conv, Fuel Tank ventilation, Secondary air system, Oxygen sensors, Oxygen sensor heater). These values don't go away until the car is driven for a few miles? Does this show up as failure on the DMV inspection? What is the Ready Status screen and it's purpose anyway?
