Circuit/System Verification
- Ignition ON, compare the scan tool BARO pressure parameter to the Altitude Versus Barometric Pressure
table. The BARO pressure should be within the specified range displayed in the table for the specific altitude.
- If not within the specified range, refer to DTC P0106
for further diagnosis.
- Compare the scan tool Secondary Air Injection Pressure Sensor pressure parameter to the BARO reading. The readings should be within 3 kPa (0.4 psi).
- Command the Secondary Air Injection Solenoid Valve Open and Closed with a scan tool. Listen and feel for Solenoid Valve operation. The Solenoid Valve should respond to the scan tool commands. Repeat as necessary in order to verify Air Solenoid Valve operation.
- Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
