O2 sensor codes
 

2000 A-6 2.8l

The CEL light is on and Im getting codes 17530(P1122), 17548(P1140) and 16544(P0160)
When I check with an ohm meter as per Audiworld tech article which tells you to check resistance at connector in engine compartment, I get a reading below 20 ohms which the article states is OK. The car they are testing in the article is a B5 A4, does that matter? Thanks......

16544

Replace the O2 sensor on the drivers side, behind the cat conveter. The O2 sensor is toast. Those OHM tests only work on specific O2 sensors.
