P1298 and P0420
I have a 02 Honda Civic EX 1.7 Vtech. It's throwing the P1298 ELD and the P0420 Catalyst Below Threshold Bank 1. Nothing is acting funny but my gas mileage is way down because of the O2 sensor and we have all ready ordered one. I also have a sound system. I have checked all fuses and wires for everything and they're good. I have also checked the voltages and nothing is over charging or low. Could someone give me advice please?
