P2212 Code - NOx Sensor Heater Sense Circuit Intermittent Bank 1
Quick Answer
The Nitrogen Oxide (NOx) sensor measures the amount of nitric oxide and nitrogen oxide in the exhaust system. Common causes include Faulty Nitrogen Oxide (NOx) Sensor, Nitrogen Oxide (NOx) Sensor harness is open or shorted, Nitrogen Oxide (NOx) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Discuss the causes and fixes for P2212 OBDII Code
-
Have 03 Jeep Liberty 3.7L 4x4. Getting code P2212 .
It has four o2 sensors 2 upstream and 2 downstream.
Want to know if this code means Bank 1 sensor 2 (downstream) ? -
Sensor 2 means downstream, but the P2212 is for the Nitrogen Oxide (NOx) Sensor and not the Oxygen (O2) Sensor. Your vehicle does not use NOx Sensor. Please double check the code number.
