Hello!
So I've had a longstanding engine warning light stuck on my dash for awhile that will, every so now and then, turn off for a little bit but eventually turn back on again. One of my friends has a spare ODBII reader so I borrowed that from him to check it out.
I believe it read P0401 (Exhaust Gas Recirculation Flow Insufficient), but we just replaced the EGR? The engine runs absolutely fine, purrs like a kitten and ain't going fast anywhere, but will still get me there even with 200k miles.
I have a multimeter and quite a few tools on hand. How can I check if the sensor is faulty or there's some other issue that I'm not seeing?
