Last week the Jeep threw the following code: P2459 dpf regen frequency

From The Dealer:
Fault code is p2459 dpf regen frequency, just did the diagnostics and it needs a diesel exhaust pressure differential sensor
Not covered under any warranty of sorts, $800.00 installed we would have to order one, could have it tomorrow

How can this sensor not be covered under the AEM Warranty?

Other Sensors That Are Covered

  • Oxygen Sensors
  • NOx Sensors
  • Intake Manifold Pressure Sensor
  • Engine Coolant Temperature Sensor
  • Fuel/Water Separator Sensor V08/V11OI
  • Intake Swirl Actuator Sensor
  • Engine Camshaft Position Sensor
  • Engine Crankshaft Position Sensor
  • Particulate Matter Sensor
  • Mass Airflow Sensor
  • Boost Pressure Sensor
  • Crankcase Pressure Sensor
  • Exhaust manifold Pressure Sensor
  • Throttle Valve
  • Exhaust Temperature Sensor
  • DPF Differential Pressure Sensor
Am I missing something here?

Notes from the Tech,
It's in a challenging spot have to remove trans cross member and jamb your hand up to get it, located on the back of the transmission @ the top.

Still working on it

Glad you got them set straight... Might check into using different service if they are trying to bypass the AEM warranty.
