I have a 2002 ford escape and 130K on it. The EGR sensor went off in March, I replaced the EGR and reset the codes, and 2 months later the exact error message came back on. I returned the part, and again installed a new EGR value and 2 days later the same code comes on???? Any Ideas?

SOURCE: 2001 Ford Escape error code P0402

Ok here is the solution when I had the exact same problem with my 2001 Ford Escape:
Replace:

Idler air control valve
EGR vaccum sylenoid
EGR valve

I did all of this work myself (and as a girl it was not hard at all), it cost me around $170.00 for all of the parts, had it done in less than 2 hrs., erased the codes and have not had a problem since then! I hope this helps you out, cuz it sure would have helped me out when I encountered the same problem.

SOURCE: How do you replace the EGR on a 2002 ford escape?

To replace the the spark plugs on the V6, you'll need to remove the intake manifold. There is a coil on top of each plug (COP). Check this website for info:

The same link will also show the R&R of the EGR valve.

SOURCE: I washed my engine on 2002 ford escape and now it has no power and egr pressure sensor keeps blowing off or melting

YOUR REAR PRE- CATALATIC CONVERTER IN FAULTY ITS THE ONE ON THE RIGHT SIDE EXHAUST MANIFOLD BETWEEN THE ENGINE AND FIREWALL AS THE INSIDES OF IT MELTS ITS GOING TO CLOG THE REAR FULL CONVERTER AND THE ENGINE WILL LOSE POWER ALL TOGETHER BUT MOST LIKLY IDLE JUST FINE
