O2 sensor

posted by  someone claiming to be bl on  Tue Feb 24 17:12 CST 2004 [RELATED]

Just installed a new front 02 sensor on a 96 850 non turbo with air pump and AT. Car continues to set CE code PO 131 ( front 02 sensor voltage low/missing). Rear sensor was replaced by PO six months ago. Pulled everything down tonight to check my splices which are fine. With car idleing, voltage directly from front black sensor wire is 0.00v which Alex Peper's software confirms. Rear sensor reads normal ( I think about .5v). Have I overlooked something or is this just a dud sensor (Bosch universal and the application # is correct for the car). The vendor is giving me the run around but thought I'd ask before sending it back to them to use as a paper weight. As it's an electrical part that has been "installed" guess I'll have to eat the $82. but did pay by CC. Many thanks
