• Q: How to remove the Air Injection Pump on 2009 Toyota Sequoia?

  A: The first step to remove the Air Injection Pump requires discharging fuel system pressure. The next step includes removing the front wiper arm and blade assembly from both right and left sides together with both front fender to cowl side seals. You must remove both the cowl top ventilator louver sub-assembly and the front wiper motor together with the link assembly. The first step requires eliminating both the front cowl top outer panel sub-assembly and the No. 1 engine under cover from the vehicle. Engine coolant drainage needs to occur before removing the throttle body cover sub-assembly along with the air cleaner hose assembly and vacuum hose assembly and the No. 2 water by-pass pipe. The intake manifold needs removal after both fuel return tube and fuel main tube disconnect. The procedure to remove the water by-pass pipe sub-assembly includes disconnecting the connector clamp before removing the bolt and pulling out the assembly to detach the O-ring. The next step involves removing the No. 1 air injection system hose by unclipping its 2 retention devices. The Bank 1 air pump assembly requires disconnecting its connector followed by removal of two bolts and two nuts. The air pump bracket can be removed after extracting all 3 bolts together with the 3 collars and 3 insulators. Ninth retainers must be removed from the front fender liner on the right side before proceeding. The installation of the No. 2 air injection system hose requires a clip remover tool to remove two clips and flipping the fender apron seal before disconnecting the air pump assembly connector and releasing two clamps and finally extracting the hose. Block out the removing process for the Bank 2 air pump assembly which consists of one bolt combined with two nuts. Finish the air pump inlet work by unbolting the 2 screws before disconnecting the No. 1 air injection system hose and No. 1 air pump bracket and removing its 3 insulators from the bracket.
