	▶ Go to "Fuel Pressure Regualtor Valve" procedure.
	▶ If no problems were found with the circuits or connectors, Replace the RPS and go to "Verification of Vehicle Repair" procedure.

warning

•

When install a part, tighten it within specification.

•

When drop down the part, check part's operating condition whether it is damaged or not.

•

After replacing RPS, perform "Component Change Routine". Otherwise, problem that performance or emission concerned can be occured from replacing the part.
