P023F Code - Possible Rodent Damage
Check engine light suddenly appeared last night with 38K miles. One code - P023F. Still under warranty, so took car in for service to local Chevrolet dealership. Couple hours later I get a call. Could be fuel pump in tank or fuel pump control module, so dealer calls GM rep to get advice on how to proceed. GM says they do not see problems with tank fuel pump on these and that there is a third possibility - rodent damage to the wiring. Requires dropping fuel tank to diagnose and customer (me) needs to approve 12 hours labor = approx. $2K. Not much choice on my part but to approve and hope for the best. Fuel pump or control module covered under warranty. Rodent damage to wiring not covered under warranty. Waiting to hear final result of their investigation. Car is garaged and is my daily driver. While we have signs of burrowing rodents outdoors, no sign of them in the attached garage.
Service writer told me I was lucky to drive the car in, as it would not start for them when they went to move it into the service area of the dealership.
Checked with my insurance company and rodent damage would be covered under the comprehensive portion of the policy.

If you have an automatic transmission, it would be a good idea to make sure the dealer is aware of the torque tube install procedure:

I experienced rodent damage to the front wheel speed sensor on my C6. Apparently the Corvette team used a soy-based wire loom that appeals to mice. Needless to say- once it finally got repaired, because the part was on backorder for a month... mouse baits were placed around the perimeter of the garage as well as an ultrasonic for extra credit.

Turns out it was a connector failure that took out the fuel pump. Not covered under drivetrain warranty but covered under extended warranty. I also sent a message to the Service Writer to make sure the technician is aware of the updated torque tube alignment procedure that was created in 2016. Given that mine is a 2017, I would hope that procedure is already in the service manual, but who knows what the technician is using as a guide for the work (if anything other than memory).
