Step-by-Step Fix Protocol for 2022 Buick Encore GX

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 B0002 set.

Step 2: Inspect Wiring Harness & Pin Voltages

Inspect the sensor connector on the 2022 Encore GX engine bay. Use a multimeter to verify reference voltage (5.0V / 12.0V) and ground continuity.

Step 3: Component Replacement & PCM Reset

Replace the verified defective component using OEM or equivalent grade parts. Clear DTC B0002 and complete an EPA drive cycle to verify readiness monitors set to READY.
