Anyone have this code and what is the most viable option to fix.
Thanks

There are several reasons

Exhaust leak near O2 sensor
Contaminated or failed HO2S2 (Sensor 2)
HO2S2 wiring/circuit problem
Loose installation of HO2S2
Fuel pressure incorrect
Faulty fuel injector
Engine coolant leak
Faulty purge solenoid valve
PCM has failed

You can rent a fuel pressure tester at most auto parts palaces. That’s where I would start

Thank you!

No problem, but test things first before you order any parts.

When I had it the cause was a Bosch #2 O2 sensor. I would start by replacing the #2 O2 sensor with a NGK/NTK; or looking at the wires to the #2 O2 sensor.

Replace the second 02 sensor. Fairly cheap and easy, almost surely the cause. Use the NHK sensor.

I didn’t want to load the parts cannon.

I agree with sparing the parts cannon.

There are a few cases, tho, where you can save the list of other possibilities for the unlikely event that ridiculously common cause isn't it.

Like P0010/13; check the wires, but it's almost always a bad solenoid section of the VVT solenoid valve. Yeah, you could check the resistance, prolly pointlessly...
