I have a 2012 Chevy Equinox with 99,000 miles. It was manufactured in 9/2011 so it falls outside the recall year for the issue I need help with. It is currently throwing a P228D code. I have replaced both the intake and exhaust
cam shaft sensors (NOT easy), cam shaft solenoids (VERY easy), cleaned the throttle body, replaced the spark plugs
and changed the oil (needed both anyway), the air filter and the fuel pump on the front of the engine
near the intake manifold.
JA: Are you certain it's the fuel pressure sensor that's in need of attention? What about the fuel rail? Have you checked it yet?
Customer: Well, the code says Fuel pressure regulator 1 exceeded control limits-pressure too high. I have been told there are 3 sensor; one in the fuel tank , one on the rail and one on the line. I'm not sure which one is regulator 1 or what I would need to check on the fuel rail.
JA: Are you fixing your Equinox yourself? What have you tried so far?
JA: Anything else you want the mechanic to know before I connect you?
Customer: I know there are a lot of issues with the prior year vehicles and believe this one is part of that group. I'm not sure what the next steps I should take are.
