Hi there, looking for some specs on a 4 wire Volvo v70 naturally aspirated 2.4lt petrol. First, it seems that they come with a 4 and a 5 wire sensor (but latter may be for turbo models?) Can anyone confirm.
Second, wondering if 4 wire is a wideband; scantool gives mV measurement but could be a conversion.
Third, wondering if there is a heat ohm spec and a signal wire and signal return V spec (if it’s a wideband).
thanks Mike. Been watching your vids on and off for a while and they are always the highest quality information and techniques.
