Step-by-Step Execution Protocol
Plug In OBD-II Scanner to RAM DLC Port
Locate the 16-pin OBD2 port beneath the driver's side steering column on your RAM. Read live sensor voltage readings while running at operating temperature.
Inspect Wiring Harness & Connectors
Examine the electrical harness leading to the monitored component for corrosion, oil soaking, or frayed heat shielding near the RAM exhaust manifold.
Install Direct-Fit OEM Replacement Part
Apply anti-seize compound to the threads (avoiding sensor tip). Torque to RAM factory specification (30–35 ft-lbs).
Execute RAM Drive Cycle to Complete Readiness
Clear active codes, then drive for 15 minutes combining steady 55 MPH cruise and 5 minutes of stop-and-go idle to set emission monitors to READY.
