Codes P1606 - P1423 are they only sensors? Would i be able to repair this myself or do i have to drop off the vehicle to the costly dealers?

 

18014 - Rough Road/Engine Torque Signal from ABS: Electrical Malfunction
P1606 - 35-10 - - - Intermittent

Try pulling the connector off the ABS module and cleaning the contacts with a electronics cleaner. Rest the codes.




P1423 - Secondary Air Injection System. Bank1 Flow too Low

Sounds like a vacuum leak of some sort.
