P2472 Exhaust Gas Temperature Sensor Circuit Low Bank 1 Sensor 3
The voltage from EGT sensor 3 on bank 1 is below the calibrated minimum. The signal indicates either a short to ground or a sensor returning impossibly low temperature.
Is it safe to drive with P2472?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelySignal shorted to ground
- PossibleInternal sensor short
- Less likelyConnector pins corroded - high contact resistance
