1996 Toyota t100 low voltage o2 sensor
Truck threw a code says low voltage on O2 sensor. Replaced it with a Bosch and is still sputtering low/rough idle like it was before acting almost like a misfire any advice helps thanks!

Check harness connector to fuse box/engine for dirt or corrosion...
Right sensor for particular engine and trans?
Low voltage can be high resistance in circuit...not necessarily the sensor though good to replace.

A check on wiring diagrams shows connections up to the ECM for signal inputs and outputs, a splice somewhere and ground in the engine bay, and battery power (I believe white wire with red stripe) through the DLC? As far as pin slots, it will depend on whether yours is automatic or standard trans and the engine size. I can upload the schematic tomorrow.
Remind me, is this sensor pre- or post- cat?
