2004.5 Spectra Technology
SUMMARY
The 2004.5 Spectra is equipped with an Engine
Management System (EMS) to monitor and manage
the engine and transaxle and the On-Board Diagnostic
II System (OBDII) and a variety of emission control
systems and components.
California emission certified Spectra vehicles meet the
SULEV emission standard. The Spectra meets the
standard due to changes made to the exhaust
emission, adoption of Continuous Variable Valve
Timing (CVVT), and a zero emission evaporative
system instead of a conventional evaporative system.
Federal emission Spectra vehicles use the Bosch EV6
6-hole fuel injector while CA emission vehicles use a
new Denso 12-hole fuel injector to achieve SULEV
levels. In addition, a new style fuel cap will be used
and a new Auxiliary Canister has been added to
decrease evaporative bleed emissions and work in
conjunction with the evaporative canister.
In this module, we have learned about the 2004.5
Spectra engine Management systems for US and
California emission standards, component locations
and system operation. Additionally we have learned
diagnosis and repairs for the various OBD II sub
systems.
