Just thinking that does 2003 saab 93 B207R has got somekinda lambda fuse for downstream sensor. Cluldnt find

upstream (afr)
downstream (cat efficiency)

neither are wideband sensors

 

[Strenoob11]

So if i get code for secondary sensor heater circuit low there is no point for looking to any fuses?

What's the actual code?

 

[Strenoob11]

Code is P0037

Sounds like rear went bad.

Bosch #16624

It all started afyer they changed somekinda turbo oil piping at workshop. Should i consider checking wires? If so how could i check it with lets say multimeter but without removing sensor from exhaust

 

[Diggs]

I would start with visual inspection first. After that if all looks good use a multimeter and check continuity.

Also could i buy an used lambda that has 197060 km on it. New one costs like 50 euros and used one 15 euros

Yes you can, but I do not recommend that.
