P0422 Main catalyst efficiency below threshold

Usually the rear 02 sensor reading bad. Look for vacuum line leaks around the intake manifold. Replace the rear O2 sensor as a last resort because that costs money.

P0455 general large leak of the Evap system.

My 1998 V70 has the charcoal canister in front of the left front wheel. The problem was next to the fuel filter, a hose had split. I replaced it with a 4" length of 1/4inch fuel line.
