P2033 Mercedes-Benz Code - Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2
Quick Answer
The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 2, Exhaust Gas Temperature Sensor Bank 1 Sensor 2 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 1 Sensor 2 circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
