Engine wiring diagrams

Hello. I have the Si model. And my issue has been two check engine codes. P0135 and p0498. I know what the codes are for, one is primary upstream oxygen sensor and the other is the canister vent valve. I have replaced both parts with OE Honda parts. I have had this car for a year now and I have both codes since. I bought it and two weeks later the codes popped up. P0135 will clear with my scanner but the p0498 will not clear and will say freeze frame on my scanner and will not wipe. I also used my cousins Mac tools scanner that can read everything and both the oxygen sensor and new vent valve read resistance and we are functioning with the tool but the car still thinks it is a fault. I have a upgraded muffler that bolted right up and a cold air intake but other than that car is stock. And the codes appeared before I did both of those upgrades and I do not know what to do. I do not want to pay a dealer to fix it when the parts have been replaced already. Engine wiring diagrams
