Customer Question

I have a problem finding the oxygen sensor heater relay
JA: The mechanics have tons of experience in that area. Are those all of the "symptoms"?
Customer: code p0155 and p0135 on 04 Cadillac deville I put new sensor and catalytic converter and code come back on
JA: Anything else I can tell the Cadillac Mechanic before I connect you two?

JA: Got it. Let's get this figured out. I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the Cadillac Mechanic about your situation and connect you two. You'll be on the road in no time.
