Bad O2 - ECU reset procedure
My mechanic told me which O2 is bad on my 2000 Boxster. He reset the check engine light. I changed the sensor. However he said there is some sequence that you have to follow in order to reset an internal code. Otherwise the car will fail the OBDII check. I found something here: http://www.systemsc.com/codes.htm
* Monitored & Set During Three Cycles; Warm-up, Driving, & Trip Warm-up Cycle - SAI, EVAP, (from cold start to operating temperature, 2 min. minimum) Driving Cycle - O2 Sensors/Heating, TWC, TRIM, (2 min. idle, 5 min. drive, 2 min. idle) Trip Cycle - Diagnosis of All ECM Systems, (2nd Driving Cycle after shut-down, 20 min. max.). Is this correct? Anyone have any luck with this procedure? I don't understand the exact sequence.... is it: cold start 2min idle 2 min idle 5 min drive 2 min idle shutdown 2min idle 5 min drive 2min idle am i right? thanks!

Car needs testing on a PST2 tester. Not always are O2 sensor faults caused by the sensor.

It's the Porsche tester for their products. it allows the vehicle to be diagnosed and systems read.
