P2031Exhaust Gas Temperature Sensor Circuit (Bank 1 Sensor 2)
The exhaust gas temperature (EGT) sensor at position 2 on bank 1 — typically downstream of the catalyst or before the DPF — reports an implausible signal. EGT sensors protect the turbocharger and DPF from over-temperature and time the regeneration cycle.
