P2235 Dodge Code - O2 Sensor Signal Circuit Shorted to Heater Circuit Bank 2 Sensor 2
Quick Answer
Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. Common causes include Faulty Oxygen (O2) Sensor Bank 2 Sensor 2, Oxygen (O2) Sensor Bank 2 Sensor 2 harness is open or shorted, Oxygen (O2) Sensor Bank 2 Sensor 2 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.

Code P2235 Dodge Description
In order to achieve the require temperature, a heater element is included inside the heated oxygen sensor. The ECM controls the heated oxygen sensor heater element based on signals from the engine coolant temperature and engine load. The ECM controls the heater element circuit by allowing current flow to ground.
The ECM monitors the voltage signal received through the heater element circuit and determines the state of the circuit by comparing the voltage detected with the factory specifications.

- Faulty Oxygen (O2) Sensor Bank 2 Sensor 2
- Oxygen (O2) Sensor Bank 2 Sensor 2 harness is open or shorted
- Oxygen (O2) Sensor Bank 2 Sensor 2 circuit poor electrical connection
