Generic (OBD-II) interpretation in the TuningBot DTC database.
The control module detected an interruption (open circuit) in the Nitrogen oxides (NOx) sensor, bank 2, heater control circuit, so the expected electrical continuity was not present.
Powertrain: engine, transmission and driveline systems.
Generic SAE-standard code: same meaning on every make.
Specific fault index within the subsystem.
Nitrogen oxides (NOx) sensor, bank 2, heater control - open circuit. The control module detected an interruption (open circuit) in the Nitrogen oxides (NOx) sensor, bank 2, heater control circuit, so the expected electrical continuity was not present.
P2218 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
