Starting the secondary air injection pump replacement begins with opening the hood to disconnect both the AIR pump inlet hose quick connect fitting and the outlet hose quick connect fitting from the pump. You must first remove the engine shield along with unconnecting the engine wiring harness electrical connector from the AIR pump wiring harness electrical connector. The elastic action of pressing the clip holding the AIR pump wiring harness electrical connector separates it from the bracket after which you must open the clip to remove the harness. First disconnect the AIR pump nuts while lowering the vehicle before you reposition the hoses of the AIR pump inlet and outlet. Finally pull out the AIR pump from its installation location. You should begin by placing the AIR pump in its designated position followed by raising and supporting the vehicle before installing the AIR pump nuts with 9 Nm (80 lb in) torque. You should install the AIR pump wiring harness electrical connector clip onto its bracket and then connect both the wiring harness and electrical connector before closing the clip. The engine wiring harness electrical connector needs attachment to the AIR pump wiring harness electrical connector. The engine shield should be reattached while placing AIR pump inlet and outlet hoses into position for connecting the pump outlet hose quick connect fitting and inlet hose quick connect fitting before closing the hood.

Start the secondary air injection pump replacement by opening the hood to disconnect the inlet hose quick connect fitting of the secondary air injection (AIR) pump along with the outlet hose quick connect fitting from the pump. Beginning the replacement starts with the engine shield removal followed by disconnecting the engine wiring harness electrical connector from the AIR pump wiring harness electrical connector. Pushing the AIR pump wiring harness electrical connector clip together opens the bracket release before separating it from the electrical connector clip . The harness can then be unclipped. The technician must lower the vehicle after AIR pump nut removal. The placement of both AIR pump hoses requires adjustment before you can take out the pump unit. Install the AIR pump by its position and raise the vehicle for support while tightening the AIR pump nuts to 9 N.m (80 lb in). Connect the bracket-to-harness clip of the AIR pump wiring harness before linking the harness to the clip and closing it. The engine wiring harness electrical connector must be connected back to the AIR pump wiring harness electrical connector followed by engine shield reinstallation and proper hose positioning of the AIR pump inlet and outlet. Finish by connecting the quick connect fitting on the pump's outlet hose and on its inlet hose to the device then recooperate the hood.

Beginning the replacement of the secondary air injection pump starts with opening the hood to disconnect the inlet hose quick connect fitting of the secondary air injection pump and the outlet hose quick connect fitting of the pump. Begin by eliminating the engine shield while disconnecting the engine wiring harness electrical connector which is attached to the AIR pump wiring harness electrical connector. Push the clip holding the AIR pump wiring harness electrical connector together and raise it to detach from the bracket while slipping off the harness after opening the connector clip. Lower the vehicle after removal of AIR pump nuts while repositioning inlet and outlet hoses that allow you to extract the pump. After positioning the AIR pump you should raise the vehicle to access it for installation. Fasten the AIR pump nuts by tightening them to 9 Nm (80 lb in). Place the AIR pump wiring harness electrical connector clip back on the bracket followed by attaching the wiring harness to the clip before closing the clip. Utilize the engine wiring harness electrical connector to join with the AIR pump wiring harness electrical connector before replacing the engine shield and installing the inlet and outlet hoses and their respective quick connect fitting on the pump. Finally, close the hood.
