Code P2204 Description

The Nitrogen Oxide (NOx) sensor measures the amount of nitric oxide and nitrogen oxide in the exhaust system. When the NOx sensor indicates that the storage capacity has been reached, the regeneration phase is initiated by the fueling management system. The Powertrain Control Module (PCM) monitors the NOx sensor and sets the code when the NOx sensor circuit voltage reading is not within the normal operating threshold for a specific engine bank.
