I have a 2019 Camaro SS with 20K miles on it. Live in Michigan.
Tried starting car last weekend and my check engine light comes on. (No issues before)
These were the codes:
P16E5 (Sensor Communication Circuit 3 High Voltage.)
P0201 (Cylinder 1 injector misfire)
P0203 (Cylinder 3 injector misfire)
P0205 (Cylinder 5 injector misfire)
P0207 (Cylinder 7 injector misfire)

What was fix?
Answer:
Took it to a Chevy dealer and they said I have chewed up wires. Possibly from a rodent? Tech said it would take minimum 2.5 hrs labor estimate. He has to remove intake I believe to get access to the wires. They are ordering all new parts instead of patching wires. I gave them the go ahead..

Wanted to share in case some one else has the same issue or has experienced it before. Thanks.

When I read all the injectors on one bank, I was going to say mice chewed the wires.

Years ago had a customer's S10 Blazer towed into the shop for a no start. Opened the hood and a squirrel jumped out. That thing ate EVERY wire under the hood, including the fender mounted antennae. It cost $2000 in labor to fix it as the harness wasn't available new anymore.

Just one bite II will solve all your problems. Has solved mine for years.

I worked for a Ford dealer many moons ago....we had a Windstar minivan come in with a no-start. Mice had made a home in the pocket underneath the cowl where the main engine harness went into the PCM.....and chewed their way through it. I forget what that repair cost but the owner's insurance paid for it.....not cheap.

Keep your hood open and windows rolled up , when car is stored and a light on, the little critters don't like light, my garage is like another room of the house , my place to relax , when not in use the door to house is closed and a light is always on. The garage door is open long enough to get a car in or out. A fellow years back I knew did this to all the cars in his shop , he never had issues.
