On the 2007 Honda Accord, the P0498 is a fairly straight forward code pointing to a fault with the EVAP Canister Vent Shut Valve. This valve is located under the vehicle, towards the rear, near the EVAP Canister. Carefully inspect the electrical connector for any loose, broken or damaged wires. Inspect the lines in the area for any cracks, holes or loose/missing connections. If the visual inspection checks ok, suspect a faulty Valve.

The P0135 is also a straight forward code pointing to a fault with the internal heater for the A/F Sensor (like an Oxygen Sensor but “smarter”). The on-board computer uses this internal heater to get the sensor to normal operating temps within a matter of seconds on cold starts. Inspect the elecrical connector and wire harness for any loose, broken or damaged wires. If the visual inspection checks ok, replacing the A/F Sensor will solve the problem. The sensor is mounted to the exhaust, before the Converter.
