S90 delayed Check Engine Light? 900

Hi All,

Have an S90 that displayed PNP failure (flashing arrow and blinking WES switch).

I rowed the shifter back and forth to clean up the PNP points, and reset the code. Success! The flashing lights were gone -Or so I thought.

The CEL light comes on approximately 5 seconds after the engine starting, yet there is no code associated with it?

Does anyone have any idea what this could be?

Thanks!
