Common rail pressure exceeds standard value for longer than standard period
during mid-range-speed or high-speed use of supply pump.
System recovers if signal becomes normal with starter switch in ON position.
• Main injections only enabled.
• Common rail pressure upper limit provided.
• Injection rate limited to predetermined value.
(Common rail pressure and injection quantity are limited.)
• Inspection of fuel piping (See Gr13A.)
• Inspection or replacement of supply pump. (Have work performed by DENSO
Service Station.)
• Pressure limiter (Have work performed by DENSO Service Station.), main
body of common rail
• Injectors (Have work performed by DENSO Service Station.)
Pressure-feed malfunction occurs because of fault in supply pump assembly
(fault in one cylinder).
System recovers (power is re-supplied to electronic control unit) if signal be-
comes normal when starter switch is turned OFF → ON.
• Main injections only enabled.
• Common rail pressure upper limit provided.
• Injection rate limited to predetermined value.
(Common rail pressure and injection quantity are limited.)
• Inspection or replacement of supply pump (Have work performed by DENSO
Service Station.)
Fuel is leaking from high-pressure part of system (calculated value).
System recovers (power is re-supplied to electronic control unit) if signal be-
comes normal when starter switch is turned OFF → ON.

B9: Fuel Leak Check
• Air-bleeding of fuel system (See Gr13A.)
• Inspection of fuel piping (from supply pump to common rail) (See Gr13A.)
• Fuel filter (See Gr13A.)
• Supply pump (Have work performed by DENSO Service Station.), main body
of common rail
• Pressure limiter (Have work performed by DENSO Service Station.)
• Injectors (Have work performed by DENSO Service Station.)
Common rail pressure is too high and fuel leakage (calculated value) exceeds
standard value.
System recovers if signal becomes normal with starter switch in ON position.
