P0130 & P0150

[SHO55]

Merging onto the highway my CEL came on. Both P0130 and P0150 were pulled. I searched the forum for answers but no one ever stated if their solutions worked. Any suggestions where to start? 2010 SHO.

Those are circuit codes for both front O2 sensors. They wouldn't both go bad at the same time, so look for electrical issues like bad battery, or bad alternator, bad ground, etc.

On the other hand, I once had bad O2 heater circuit codes (all four) on my '97 Cougar - turned out the PCM went bad.

My thoughts exactly. I just have no clue where to start.

The pcm is under the cowel, you'll have to follow the harness to the 02s and perform a visual to see if you can see a chafe. There are no connectors between the upstream and pcm for inspection.

Other than that, a wire diagram and multimeter to start testing circuits.
