Does the check engine light come on when the key is turned on?Check fuses #11, #15, #18, #23, #40. Make sure thee fuses have power when the key is turned on.

Sorry I went out of town. Yes all of these fuses have power with the key on. The CEL comes on with the key and stays illuminated.

What fixed the problem?
Customer: replied 2 years ago.
Bank 2 sensor 2 HO2 wiring came in contact with front driveshaft and shorted. What I thought was a spare fuse was actually the PCM diode / HO2 sensor fuse. Replaced sensor, routed pigtail to avoid problem in the future, scanned to check communication, cleared codes and road test.

I can't believe I missed the fuse. Smh... In a rush, was getting ready to leave town. As soon as I came back fresh I figured it out right away. Lol

I have to do that al lot at the dealership. I get involved in a problem vehicle, and my service writer stops me to do another vehicle, then I get back to the first one and he rushes me. I have to stop, stand back, have coffee or a drink, then get back into it. It happens every day with me.
