Hello,
The codes:
P0135 : A/F Sensor (Sensor 1) Heater Circuit Malfunction
P0498 : EVAP Canister Vent Shut Valve Circuit Low Voltage
While either of these codes could be due to faulty components like oxygen sensor or the vent valve. It could be due to fault within the circuit, like a bad ground or shorted out wire.
I have attached the step-by-step trouble shooting guide for these codes below. Follow those steps as it can help you determine the issue.
Please let me know if you have any questions.
Thank you.

Thank you for info. The car was in front end accident body shop could not figure out issues with codes after body work. Ended up being a wire from the o2 sensor was damaged and grounding against metal intermittently. Had to replace sensor as well since it must have also affected sensor heating up within spec.
