Most Reported On
P2200 is an OBD-II diagnostic trouble code meaning “NOx Sensor Circuit Bank 1 Sensor 1.” P2200 is a generic powertrain code indicating the engine control module (ECM) has detected a fault in the electrical circuit of the NOx (nitrogen oxide) sensor for Bank 1, Sensor 1. This sensor measures NOx concentration in the exhaust as part of the emissions aftertreatment system (typically SCR/DEF on diesels), and the code means the circuit is open, shorted, or producing an out-of-range signal. This code is most commonly reported on 2015-2020 Mercedes-Benz V-Class (V200 d, V220 d, V250 d), and 2016-2024 Mercedes-Benz GLE (GLE 250d, GLE 300d, GLE 350d, GLE 400d, GLE 450d), with repair costs ranging from $300 to $1,200.
