Almost never does those codes reflect the real problem but it might be an obscure wire/terminal crimp connection that has deteriorated to a point where not enough juice is flowing through at very specific temperatures or engine vibrations and then being perfect at all other driving occurrences.
A pure nightmare for technicians and owners to deal with.
The first approach is to reset fault codes and see if it comes back right away or if any running problems are noticed.
If nothing is wrong, disconnect connector at pedal, ECM and throttle body and check for corrosion and treat terminals with Stabilant 22 or any other contact enhancer and then let the customer drive the car and see how many days, weeks, month or years it take for the problem to come back and how interested the owner is to really get it fixed.
