Check exhaust manifold near Bank 1 Sensor 1 for cracks or blown gaskets sucking in fresh air. on the Dodge Hornet equipped with 2.0L Turbo (265HP) / R/T PHEV (288HP / eAWD).

Required Tool: Flashlight, Mirror
02
Monitor Air-Fuel Sensor Current / Voltage

Required Tool: OBD-II Scanner
03
Introduce Propane/Carb Cleaner to Test Response

Briefly spray unlit propane into intake. If sensor voltage does not quickly drop rich, the sensor element is poisoned. on the Dodge Hornet equipped with 2.0L Turbo (265HP) / R/T PHEV (288HP / eAWD).

Required Tool: Propane Torch Valve or Carb Cleaner
04
Replace Upstream Air-Fuel Ratio Sensor

Install a new genuine OEM Denso / Bosch upstream A/F sensor. on the Dodge Hornet equipped with 2.0L Turbo (265HP) / R/T PHEV (288HP / eAWD).

Required Tool: 22mm O2 Sensor Socket, Ratchet
