im getting this code 16514 P0130 O2 Sensor Circuit - Malfunction (Bank 1 Sensor 1) A

so i changed the sensor yesturday cleared the code drove for 30 minutes light stayed off. parked for 20 minutes and when i got 1500 feet the llight came back on


so what should i check now? i want to get this figured out without going to the dealer....

the car is a 2002 1.8tq A4

 

the light came back but did you get it scanned again? it could be a code for B1S2 this time because the 2 sensors work together and there is a range where everything is right. the new sensor could mess with things a little bit but it should correct itself. car should run fine too.

 

yea the car is running fine now.. better then it was b3fore but the light is back on.. im going to get it scanned again now so hopefully itll be ok
