Hi All,

I am new to your forum and need to lean on your technical expertise.

I have just downloaded the following code from my 2003 MY Boxster S ( 50 k miles ) after the CEL illuminated for the first time. No other codes or pending codes logged. ( Last routine download 2 yrs ago )

P 2096 : Signal delay time for oxygen sensor ageing limit. The car is running sweet as with no obvious signs of any problems. The vehicle recently passed a UK annual emmissions test.

Can anyone suggest an informed diagnosis. Apparently it needs two fault readings on two consecutive engine cycles so unlikely to be spurious. Could it be something as simple as a failing post cat O2 sensor on bank 1 or something more sinister. I am beginning to uncover threads for this code activation leading to a dying or damaged catalytic converter.

My basic understanding is that it is telling me that there is too much air/ 02 ( lean ) exiting the cat.

I have reset the code and the CEL has extinguished on idle. Due to seasonal scottish weather I haven't had a chance to test run the car for any distance.

Thanks for your help.

P2096 Signal Delay Time for Oxygen Sensor Aging - Above Limit

Possible fault cause

- Oxygen sensor

Erase the code and if it returns then fault trace the problem, but it sounds like the O2 sensor is slow to respond and will need replacing. Often recommend to replace units in pairs.
