P2466 Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 3
A general circuit fault is detected on the EGT sensor at bank 2 sensor 3 (typically just downstream of the turbo or before the catalyst). The ECU loses thermal protection feedback for the catalyst and DPF.
Is it safe to drive with P2466?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
