Circuit/System Verification

NOTE: Do not run secondary air injection pump for more than 1-2 minutes at a time. Running for an extended period of time without allowing pump to cool may cause damage to the pump.
  1. Ignition ON, observe the DTC information with a scan tool. Verify that DTC P2431, P2432, or P2433 is not set.
  2. If a DTC is set, refer to Engine Management And Fuel System, V6 DTC Index for further diagnosis.
  3. Observe the scan tool Secondary Air Injection Pressure Sensor voltage parameter. The reading should be between 1.0-4.0 V.
  4. Compare the scan tool BARO pressure parameter to the ALTITUDE VERSUS BAROMETRIC PRESSURE table. The BARO should be within the specified range displayed in the table for the specific altitude.
  5. If not within the specified range, refer to DTC P2227, P2228, OR P2229 (LAU) for further diagnosis.
  6. Ignition ON, command the Secondary Air Injection Pump Relay ON and OFF with a scan tool. The secondary air injection pump should turn ON and OFF.
  7. Engine running, command the Secondary Air Injection Pump Relay ON with a scan tool while observing the Secondary Air Injection Pressure Sensor parameter. The reading should change greater than 10 kPa (1.45 psi).
  8. 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.
