Bosch ME9 engine management
system, V6 engineThe Bosch ME9 engine management
system is a system that combines sequen-
tial multiport fuel injection, electronic distrib-
utorless ignition and turbocharger boost
pressure control into one system and intake
camshaft phasing control.
The ME9 engine control module (ECM)
monitors many different engine parameters
such as:
Charge air pressure
Intake air temperature
Crankshaft position
Engine coolant temperature
Throttle position
The oxygen content of the exhaust gases.
By processing all of this information, the
ME9 system can contro l fuel injector open-
ing duration, ignition timing, intake camshaft
phasing and turbocharger boost pressure to
provide excellent engine performance while
maintaining low emissions and fuel con-
sumption.
ORVR (Onboard Refueling Vapor
Recovery)All hydrocarbons formed when refueling will
be recovered by the car and not released
into the atmosphere. The hydrocarbons are
absorbed in an evaporative emission canis-
ter. When the engine is subsequently
started, the evaporative emission canister is
gradually purged as air is sucked into it
through a shut-off va lve. The hydrocar-
bon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. “ Refueling”, see
page 156.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 3 times.
NOTICEThe ME9 engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the Service
Engine Light also known as CHECK
ENGINE light in the main instrument illu-
minates, the ME9 ECM has detected a
problem. The car will continue to operate,
but performance may be diminished. You
should have your car checked by a work-
shop as soon as possible. We recom-
mend that you contact a Saab dealer.
