2004 Blazer Codes P0200, P0155, P1133, P0303
My Blazer had these codes about 2 weeks ago. I replaced the oxygen sensors. Since then, my engine light went out and has now come back on. I got the same codes again. Any suggestions on what I can do to solve this problem? I have put about 600-700 miles on the new oxygen sensors.
Thanks |

What engine is in the vehicle?
DTC's must be diagnosed and repaired in the order they are retrieved. As you posted, P0200 is the first one, which is an open injector circuit. Any DTC's that appear after the first one can be set as a result the first DTC. In your case, the second and third are both oxygen sensor issues which could be caused by an injector not opening. The fourth DTC is indicating a misfire on #3 cylinder. With the ignition in the RUN position, engine off, check voltage on both terminals of injector #3 and post your results.
