2006 Toyota Land Cruiser Air Injection Pump Parts Questions & Experts Answers

• Q: How to service and repair the Air Injection Pump on 2006 Toyota Land Cruiser?

  A: The service and repair of the Air Injection Pump demands an initial step of fuel system pressure discharge and negative battery terminal cable disconnection for at least 90 seconds to stop Air Bag and seat belt pretensioner activation. You should drain the engine coolant then take out the V-bank cover sub-assembly before cutting the fuel return and main hoses. Service the Air Injection System by beginning with intake air connector pipe and intake manifold assembly removal and finally removing the vacuum control valve set through disconnection of the 2 bolts and valve set from the intake manifold along with the 2 vacuum hoses. Begin air pump assembly removal by disconnecting No. 2 air hose and air switching valve connector and pressure sensor connector before removing its securing 4 bolts. To remove the No. 2 air switching valve proceed by removing 4 nuts combined with 2 gaskets and disconnecting 2 No. 3 air tubes from the exhaust manifolds. Then install the 4 bolts alongside 2 gaskets and 2 No. 3 air tubes on the 2 No. 2 air switching valves. Additional steps involve removing the 4 bolts with 2 gaskets and 2 No. 2 air switching valves from the rear water by-pass joint followed by uninstalling 2 vacuum hoses from the No. 2 air switching valves. Disconnect both connectors from the air injection control driver followed by removing its two bolts. Start by attaching the air injection control driver into position with its two bolts torqued to 19.5 N.m before linking the two connectors. The process starts by connecting the vacuum hoses to No. 2 air switching valves before placing new gaskets and installing the valves to the rear water by-pass joint with 4 bolts at 10 N.m torque. Afterward, secure the No. 3 air tubes to the exhaust manifold with 4 nuts at 10 N.m torque. Insert the air pump assembly using 4 bolts which need a torque of 16 N.m. Also reinstall the pressure sensor connector and the air switching valve connector and the No. 2 air hose. Fasten the vacuum control valve onto the intake manifold via 2 bolts while tightening it to 7.5 N.m and proceed to connect both vacuum hoses. You should reinstall the intake manifold assembly after connecting the fuel main and return hoses together with the intake air connector pipe as well as the V-bank cover sub-assembly. Reconnect the cable to the negative battery terminal and perform initialization during which specific systems must be initiated apart from reconnecting the cable. After this you should add engine coolant while checking for both engine coolant and fuel leaks.
