I am sorry as this model is not in our country, our safety standards are a physical test and inspection in a test center. Vehicles with a computer code should be taken to a dealer for a down load and a estimate or quote given, then it is up to you where you get this work carried out. Be careful some times the dealer can repair better than some independent shops, get 2 or 3 estimates first. P

As for your codes p1131 and 1151: Ford - Lack Of Heated Oxygen Sensor Bank 1 Sensor 1 Switches - Sensor Indicates Lean

Last week I had the very same catalyst, evap and ECG codes come up on my 1999 Mercury Mystique which is like a Ford Taurus. A friend was able to find a hole or leak in the hose connected, replaced it and it runs fine. I havent run it a full and straight 50 miles yet to clear the check engine light but that repair alone changed the entire way the car was poorly driving. Im sure that hasnt fixed all the probs but thats a good starting point.

What is causing a P1131 code on 2000 ford excursion?

P1131----- H2Os-11 running lean.
Here are some possible causes:
Dirty or malfunctioning mass air flow sensor ( mounted in the air intake hose that goes from the air filter to the throttle plate).
Vacuum hose leaking
Intake manifold gasket leaking air
Low fuel pressure
Dirty fuel injectors
This is where testing has to be done to pin point the cause without having to replace things you don't need to.

I have a 2000 ford winstar with a code 1131 what

This has to do with your bank one O2 sensor. You may just need to clean it off, possible you may have to replace it.

A p1131 code is the 02 sensor on bank #1 switching slowly, causing a lean mixture.
First check for a vacuum leak in anyone of the vacuum lines,which will cause this code. If all the lines are good, replace the sensor.
