  1. Air intake chamber must be removed for access to fuel rails and fuel injectors. See Figure and Figure . Release fuel pressure. See FUEL SYSTEM PRESSURE RELEASE .
  2. On Camry Solara, remove suspension upper brace. Suspension upper brace fits between strut towers and is bolted to top of each strut tower. On all models, remove air cleaner hose and "V" bank cover. See Figure and Figure . On Camry Solara, remove bolts and engine mount support brace for engine mount at timing belt end of engine. Engine mount support brace fits from top of coolant housing to the engine mount.
  3. On Avalon, disconnect control cables, electrical connectors, vacuum hoses and coolant hoses at each throttle body. On Camry Solara, remove spark plug wire assembly if necessary for access to air intake chamber and intake manifold. Disconnect control cables, electrical connectors, vacuum hoses and coolant hoses at throttle body.
  4. On all models, disconnect electrical connectors and vacuum hoses from vacuum switching valves on emission control valve set located on side of air intake chamber. See Figure and Figure .
  5. On Avalon, remove data link connector No. 1 from bracket on end of air intake chamber. See Figure. On all models, remove nuts and disconnect power steering pressure tube from engine hanger.
