I recently had a check engine light. When I connected to my code scanner I received a DTC52 which is power steering pressure switch circuit open. I do not have power steering. There was also a DTC12. It initially read that the deceleration vacuum switch was open constantly. Where is the switch located so I can replace it. Thx.
