SignUp Now!nah keeps saying low voltage in heater circuit on both front sensors.
so the fuse and relay are good. the sensors never been took out just unplugged. dropped tranny while back but didn't get code til done exhaust. o2 sim took the codes off for o2 sensor in back. I had my exhaust manifolds off to weld down pipe on.
I've run dtlt's for a long time before parting out most of my goodies, and I too get two specific codes, sometimes both, sometimes one or the other... po138, po157 and I think It was mainly due to the lack of cats, or I fumbled the removal of the o2 sim. Going through this myself, but I find the codes only come every 40-50 miles or so from clearing. Thoughts, G?
