INSPECTION AFTER INSTALLATION
Check For Fuel Leaks
1. Turn ignition switch “ON” with the engine stopped. With fuel pressure applied to fuel piping, check for fuel
leaks at connection points. Repair as necessary.
NOTE:
Use mirrors for checking at points out of clear sight.
2. Start the engine. With engine speed increased, check again for fuel leaks at connection points. Repair as
necessary.
WARNING:
Do not touch the engine immediately after stopped, as the engine becomes extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.
• Perform procedures for “Throttle Valve Closed Position Learning” after finishing repairs. Refer to
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to
