1992 Lexus SC400 Base 8 Cyl 4.0L


Code 21,28 were causing my check engine light to come on I replaced both front 02 sensors, erased the codes to no avail

Any ideas? is there a fuse that could be connected not allowing them to heat up? I'm hoping its a fuse or simple wiring issue and not the engine control module.
