Review on ACDelco 214 2128 Original Equipment Injection by Ryan Gillett

I purchased this replacement valve for my Cadillac DTS after the check engine light came on. After an OBD2 scan, I received an error code related to the secondary barometric pressure sensor failure. The actual sensor is built into this check valve and can only be replaced by replacing the entire check valve. This is a genuine AC Delco part and I replaced the valve myself which took about 45 minutes with minimal tools other than a 10mm socket. After changing the valve I disconnected the battery for 2 hours to reset the OBD2 and after 1000 miles I haven't had any repeat problems. My transaction showed a replacement at 500.00. This is a pretty easy project that can save you hundreds of dollars.
