I had 17523 and 17525 oxygen lambda both sensors: Short to ground

After erasing foults started engine and run for 1 min. i checked again to see if foult will come back and he did but in diffrent code wchich was 16524

wheres others codes gone? why they changed to diffrent? after running car longer i had again first 2 codes:P weard. but i found problem its was.....

Fuse... lol i got 2 new lambda sensors and spnd over 100 pounds on them. Foult still come back. After checking fuze and replace it was ok i waisted money:// maybe ebay old good sensor now? or maybe u wanna buy? ^^ i sell cheeper

If u checked fuze and it was good then maybe sensore is really nakerd and u need to get new one. all i know u need to look at second sensor behind catalystic convertor. Engine>>B1 S1>>>>Catalystic converter>>>> B1 S2 (your foulty sensor) U want to check wires as well as connectors on that sensor
