P2470: Exhaust Gas Temperature Sensor Circuit Intermittent Bank 1 Sensor 3
Standardized SAE J2012 code · P24xx — Auxiliary emission controls
What does P2470 mean?
The exhaust gas temperature sensor 3 on bank 1 (often after the DPF) shows intermittent dropouts. Erratic readings disturb DPF regeneration logic.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Intermittent connector
- Medium Chafed wiring near hot exhaust
- Low Harness routed against vibrating component
