WARNING: This page is about a different variant/trim than selected.
NOTE:

The following removal and installation procedure is for the left lower section of the intake manifold. The procedure for the other side is identical.

WARNING:

There is a risk of injury because the fuel is under very high pressure.

  • Before opening high pressure area of the fuel injection system, fuel pressure must be relieved to residual pressure. Refer to BEFORE OPENING HIGH PRESSURE FUEL INJECTION SYSTEM 
  • To reduce remaining residual pressure, lay a clean cloth around the connector and carefully loosen connector.
