Removal (Camry)

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2003 Toyota Tundra, 2003 Toyota Tacoma, 2003 Toyota Sienna, 2003 Toyota Sequoia, and 2003 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
  1. Air intake chamber and intake manifold must be removed for access to knock sensors. Knock sensors are located on cylinder block, just below cylinder heads. See Figure.
  2. Release fuel pressure. See FUEL SYSTEM PRESSURE RELEASE  under FUEL SYSTEMS.
  3. Drain cooling system.
  4. Remove suspension upper brace. Suspension upper brace fits between strut towers and is bolted to top of each strut tower.
  5. Remove air cleaner hose and "V" bank cover. See Figure.
  6. Disconnect control cables, electrical connectors, vacuum hoses and coolant hoses at throttle body.
  7. Disconnect electrical connectors and vacuum hoses from vacuum switching valves on emission control valve set located on side of air intake chamber. See Figure or Figure .
  8. Remove nuts and disconnect power steering pressure tube (if equipped) from engine hanger.
  9. Disconnect necessary electrical connectors, ground straps and vacuum hoses for removal of air intake chamber and intake manifold.
  10. Disconnect PCV hose from PCV valve on rear cylinder head.
  11. Remove bolts, engine hanger and air intake chamber support brace from air intake chamber. Remove nuts, EGR pipe and gaskets (if equipped). See Figure or Figure .
  12. Remove bolts/nuts, air intake chamber and gasket. Note location of electrical connectors on fuel injectors for installation reference. Disconnect electrical connectors at fuel injectors.
  13. Remove fuel pipe clamp from disconnect fitting at end of No. 1 fuel pipe. See Figure. Ensure area around No. 1 fuel pipe and disconnect fitting is clean.
    CAUTION: Use care when disconnecting No. 1 fuel pipe from fuel pipe fitting, as some residual fuel pressure may still exist in the fuel system.
  14. Depress both tabs and pull No. 1 fuel pipe with disconnect fitting from fuel pipe fitting. See Figure.
  15. Disconnect coolant hoses at intake manifold. Remove bolts/nuts and intake manifold with fuel injectors and fuel rails as an assembly. Remove gaskets for intake manifold.
  16. Disconnect electrical connectors and hoses for removal of coolant housing. Coolant housing is located on cylinder block, in front of intake manifold area. See Figure and Figure . Remove bolts/nuts, coolant housing and gaskets.
  17. Disconnect electrical connectors at knock sensors. Remove knock sensors from cylinder block using Oil Pressure Switch Socket (SST 09816-30010), or equivalent.
