Fuel Pressure Relief ProcedureS7RS0B1706003
CAUTION!
This work must not be done when engine is
hot. If done so, it may cause adverse effect to
catalyst.
NOTE
If ECM detects DTC(s) after servicing, clear
DTC(s) referring to “DTC Clearance in

Repeat this (ON and OFF) 3 or 4 times and apply
fuel pressure to fuel line until fuel pressure is felt by
hand placed on fuel feed hose.
2) In this state, check to see that there are no fuel leakages from any part of fuel system.
Fuel Lines On-Vehicle InspectionS7RS0B1706005
CAUTION!
Due to the fact that fuel feed line (1) is under
high pressure, use special care when
servicing it.
Visually inspect fuel lines for evidence of fuel leakage,
