hello peoples!
I recently installed some Schmiedmann headers *ca 100 kms ago or 2 weeks*
(though it shouldnt change anything)
and ive been getting this same pre cat error which is causing my motor lamp to show up
96 [150] Oxygen sensor voltage before catalyst bank, 1 open circuit
Things i have done to troubleshoot:
Swapped the connectors around from lambda 1 and 2
Same code, no difference
followed the cable up to the ecu not cut or anything
Read something about this is a common issue on e46s which just needs a motor reprogram, does this apply to e39s as well?
Only other thing i could imagine it being would be that i cut a single cable in the harness when trying to cut a cable tie
Only got access to PaSoft software and the other codes are from where i started it with only headers ;p
Also as you can see on the images the bank 1 o2 sensor is touching the block but i dont think that has anything to with it because the error code didnt go over to bank 2 after i swapped the lambdas
Will get the touching part grinded down and bend the exhaust part a bit
really stumped on this really would appreciate some help :D:devillook
