Answer 1

 

the 2008 warranty says

Emission Performance Warranty - 

8 years or 80,000 miles*

•  Catalytic converters

•  The electronic emissions control unit or computer (ECU)

•  The onboard emissions diagnostic device or computer (OBD)

 

 

Emission - Emission Components Warranty -

3 years or 36,000 miles*

Exhaust Gas Conversion Systems: oxygen sensor, thermal reactor, catalytic converter, 

dual-walled exhaust pipe

2. Exhaust Gas Recirculation System: EGR valve, thermal vacuum switch, EGR solenoid, 

EGR spacer plate, EGR backpressure transducer, sensor and switches use to control EGR 

flow

3. Evaporative Emission Control System: purge valve, fuel filler cap, purge solenoid, vapor 

storage canister and filter

4. Positive Crankcase Ventilation (PCV) System: PCV valve, PCV solenoid

5. Air Injection System: Air pump, diverter, bypass, or gulp valve, reed valve, anti-backfire 

or deceleration valve

6. Early Fuel Evaporative (EFE) System: EFE valve, thermal vacuum switch, heat riser 

valve

7. Fuel Metering System: electronic control module (unit) or EFI air flow meter, computer 

command module or mixture control unit, deceleration controls, electronic choke, fuel 

injectors, fuel injection units and fuel altitude compensator sensor, bars or rails for EFI 

or TBI systems, mixture settings on sealed fuel mixture control solenoid, diaphragm or 

other systems, fuel metering components that achieve closed/other feedback control sen

sors/loop operation switches and valves

8. Air Induction System: thermostatically controlled air cleaner, air box

9. Ignition Systems: electronic spark advance timing advance/retard systems, high energy 

electronic ignition

10.Miscellaneous Parts: hoses, gaskets, brackets, clamps and other accessories used in the 

above systems
