Step-by-Step Fix Protocol for 2020 Kia Telluride

Step 1: Scan & Record Freeze Frame Data

Connect an OBD-II scanner to the DLC port under the driver dashboard. Record engine RPM, Short Term / Long Term Fuel Trim (STFT/LTFT), and engine coolant temperature at the moment P0506 set.

Step 2: Inspect Wiring Harness & Pin Voltages

Inspect the sensor connector on the 2020 Telluride engine bay. Use a multimeter to verify reference voltage (5.0V / 12.0V) and ground continuity.
