P0404 is a diagnostic trouble code (DTC) for "Exhaust Gas Recirculation Circuit Range/Performance". This can happen for multiple reasons and a mechanic ...
im looking at that circuit , on the start relay on your radiator support , red is always hot via fusible link , purple to solenoid as you say , orange/black wire should be hot in run or start mode , if it is not the fuse for that wire is PCM/ABS 10 amp located fuse block in driver door jam , it does go through the nuetral saftey switch , the yellow wire going to the PCM must ground that relay to activate start mode . last note there is a PCM/CRANK fuse in the driver door jam also , 10 amp , if all this is good i would like to hear more . 1 more note about the nuetral saftey switch is the pink wire going in and the orange/black wire coming out should have continuity in park and nuetral ....let us know thanks
This reply probably too late but -
> Is this a wiper motor problem? The motor may be OK but the parking switch has likely failed. It should normally supply power until they reach their parking spot unless the main operator switch is still on and this probably controls a relay that may be faulty. If you have had the problem corrected, you might post the problem found back here as a comment to aid others.
It's in the under hood fuse box. Hopefully the fuse box has a legend on it that will tell you which relay is which? Your owners manual may have this info? Some owners manuals you can look at online for free. Notice ac clutch relay in diagram.
Good Morning Gary, would love to get a little more information from you. This vehicle actually has two sensors in the exhaust that deal with Oxygen and fuel to help the engine run correctly. The one you are probably asking about is on the exhaust about 6-12 inches from the exhaust manifold. It should have 4 wires running to it and be screwed into a threaded port on the exhaust pipe. This sensor is called sensor 1.
On the high pressure side of the system on the line that goes into the evap just at the engine compartment firewall. Sometimes it is wrapped with an insulation and is hard to find.
In order to reach the negative terminal to the battery in a 2000 Vebture (I have one) you must first remove the fuse housing. The fuse housing is a large black box that sits atop the battery. There os a single bolt that holds it in place located in fron of the battery bolted into the lip of the motor bay. Unscrew this, then unhook the fuse housing from the cross bar running from the back roght to the front of the motor bay. This is a tight fit so watch your knuckles. Once the fuse housing is out, the negative terminal is located on the backside of the battery. It is a tight squeeze black is negative, red is positive.

You put the starter wires back on the same way they came off. If the wiring diagram doesn't help, not sure where to go from there?
The button is not working. It's programmed if the other functions (buttons) work. What you can do is take it apart, clean the rubber part (the buttons) with soap and warm water. Then, use a cotton swab and rubbing alcohol to clean the circuit board where the back of the buttons contact the board.
Without testing we'd only be guessing , your best bet ,take it to a qualified repair shop that has the diagnostic skill's an testing equipment . Hooking up a professional scanner .

If you think the problem is a fuse or circuit breaker, I see three fuses and a circuit breaker. Use a test lite and check voltage at circuit breaker and fuses, some are hot all the time, I believe one goes hot with the key on.
the first thing to do is to have the oil pressure read using a mechanical gauge
that ensures that you know that the engine is running with the right oil pressure
you can test the ECM operation by using a substitute ECM that is a known good unit
run the fault codes to see in the oil pressure sensor is a problem
At this point , test the oil pressure as suggested then change the oil pressure sensor
