My P0420 And 430 Code Came Up Could It Just Be 02sensor Im Not Loosing Power In My Converters And They Said That What That Code Means Need New Converters on 2006 Mercedes-Benz E350
If the codes are there there is a problem. The longer you drive with codes illuminated the longer the problem is occurring and the more potential damage is being done to other components,
Someone will need to DIAGNOSE the systems involved and come up with an answer as to what has failed, not just guess and throw parts at the car. Accept the fact and spend the $$ to get an answer from a reputable shop. Cheap is not good in this case.
Call 703-449-9000 for an appointment.
I Need Radio Code on 2008 Honda Civic
You need to go to the Honda dealer with proof that you own the car and they can provide the radio code. It is a factory security measure.
What Is Causing The Problem With My Ac Condensor? on 2014 Subaru Forester
You probably mean that the AC Compressor (not condensor) is not coming on. The condenser is not capable of "coming on". There might be a pressure control switch in it though.
Chances are that a wire or harness or connector got dislodged during the battery replacement. Someone will need to trace down the circuit and verify all connections.
Please call Master Mechanic on Sullyfield Circle in Chantilly at 703-449-9000 after 8am Monday morning to schedule a convenient time to stop by with your Subaru and get the problem checked out.
