Engine Performance problem
1996 Nissan Sentra 4 cyl Front Wheel Drive Automatic 100000 miles
I got some performance issues with my car. The first thing it happen when I hear a noise at my engine, I didn't know at that time what happen, but I found later that a hose around the EGR valve exploded. My car was still driveable, but the light " check engine" turned ON. I try to pass my fumes test and I didn't pass, the problem the machine read from my car computer was:
P0401 - EGR Valve FLOW.
This is when I found and changed the exploded hose and after that I pass the fumes test. But shortly after the lproblem came back, and the " check engine" light came back on, and the engine dont run that well, especially when it is hot outside.
I foundthat the code 401 means:
Exhaust Gas Recirculation Flow Insufficient Detected.
How can I fix this, changing the EGR VALVE will be enough?
