Refer to Engine Controls Schematics MAF, Secondary Air Injection Pump Bypass Solenoid, IAC and Secondary AIR Pump . Circuit Description The AIR pump is used on this vehicle to lower tail pipe emissions on start-up. The powertrain control module (PCM) grounds the AIR pump relay control circuit, which energizes the AIR pump. The PCM also grounds the AIR solenoid valve control circuit, which energizes the AIR solenoid valve. The AIR solenoid valve opens allowing manifold vacuum to open the AIR control valves. The PCM enables both control circuits when AIR system operation is desired. When the AIR system is active, the AIR pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR control valves replace the conventional check valves. When the AIR system is inactive, the AIR control valves prevent air flow in either direction. DTC P0412 applies to the AIR solenoid control circuit. DTC P0418 applies to the AIR pump relay control circuit. DTC P0410 sets if an air flow problem is detected. The PCM will run two tests using the heated oxygen sensor (HO2S) voltage to diagnose the AIR system. Both tests have two parts. The passive test is performed during regular AIR pump operation. The passive test consists of the following: Passive Test Part 1 When the AIR system is enabled, the PCM monitors the HO2S voltage. If the HO2S voltage goes below a threshold, the PCM interprets this as an indication that the AIR system is operational. Passive Test Part 2 When the AIR system is disabled, the PCM monitors the HO2S voltage. The HO2S voltage should increase above a threshold and switch normally. If both of these tests indicate a pass, no further action is taken. If one of the above tests failed or is inconclusive, the diagnostic will proceed to test two. The active test is performed specifically for diagnostic purposes. Test two consists of the following: Active Test Part 1 During this test the PCM turns the AIR system on during closed loop operation. When the AIR system is activated, the PCM monitors the HO2S voltage. If the AIR system is operating properly, the HO2S voltage should go below a predetermined threshold. Active Test Part 2 The PCM turns the AIR system off. The HO2S voltage should return to above a rich threshold.

Removal of Factory Intake 1. 2. Turn the ignition OFF and disconnect the vehicle’s negative battery cable. Loosen and remove the two bolts that secure the air inlet duct to the radiator core support, then remove the air inlet duct. Loosen the clamps at the air cleaner assembly and turbo inlet tube, then remove the stock intake tube. Loosen and remove the two bolts that secure the air cleaner assembly. Pull upwards to remove the air cleaner assembly. Using the bolt removed to secure the ABS control bracket. Loosen and remove the two screws that secure the mass air sensor to the air cleaner assembly, then remove the mass air sensor. Raise the vehicle and support with the jack stands, then remove the front passenger side tire. Remove the five plastic push/screw clips that secure the inner wheel house valance. Remove the 6 screw in push clips that secure the air duct to the lower valance, then remove the air duct. Remove the two remaining push clips that secure the lower valance, then pull the valance down. From inside the apron, remove the push clip that secures the apron to the upper fender. Remove the hex nut that secures the air intake resonator to the inner fender. Loosen and remove the second hex nut that secures the air intake resonator from underneath the vehicle. Remove the air intake resonator. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. Install of Intake 16. Install the reducer and clamps onto the turbo and secure. 17. Loosen and remove the hex bolt on the cam cover. 18. Using the provided allen bolts, secure the mass air sensor into the adapter on the intake tube. 19. Using the allen bolts, secure the mass air sensor into the adapter on the intake tube. 20.
