U.S. and Canada model Insights are equipped with On-board Refueling Vapor Recovery (ORVR) systems that are identical to the system introduced on the 1998 Accord.

The following diagram shows the entire vacuum distribution system including the ORVR system:

1. Primary heated oxygen sensor (primary HO2S)
2. Secondary heated oxygen sensor (secondary HO2S)
3. Manifold absolute pressure (MAP) sensor
4. Intake air temperature (IAT) sensor
5. Engine coolant temperature (ECT) sensor
6. Top dead center 2 (TDC2) sensor
7. Top dead center 1 (TDC1) sensor
8. Crankshaft position (CKP) sensor
9. Knock sensor (KS)
10. Master power vacuum sensor
11. Check valve
12. Brake booster
13. Idle air control (IAC) valve
14. Fuel injector
15. Fuel pressure regulator
16. Fuel filter
17. Fuel pump (FP)
18. Fuel tank
19. Throttle body (TB)
20. Air cleaner
21. Resonator
22. Positive crankcase ventilation (PCV) valve
23. Exhaust gas recirculation (EGR) valve
24. Three way catalytic converter (TWC)
25. NOx adsorptive three way catalyst
26. Evaporative emission (EVAP) control canister
27. Evaporative emission (EVAP) control canister filter
28. Evaporative emission (EVAP) purge control solenoid valve
29. Evaporative emission (EVAP) control canister vent shut valve
30. Evaporative emission (EVAP) two way valve
31. Evaporative emission (EVAP) bypass solenoid valve
32. Fuel tank pressure sensor
33. Onboard refueling vapor recovery (ORVR) vent shut valve
34. Onboard refueling vapor recovery (ORVR) vapor recirculation valve
35. Purge joint
