Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

CODE SHOWS EGR VALVE


Is the code 401? Because if it is then it's not your egr its the sensor switch for the egr. It's located back by the firewall it is a black 1 1/2" x 2 1/2" rectangular shaped ,plastic and has a clipped plug on it's long side and it has 2 rubber sleaves coming out of bottom which slide over 2 vacuum lines to the egr and if this sensor has any moisture in it what so ever then you have to replace it. This sensor makes the egr valve open and close. And the tribute are famous for these sensors failing. The Ford part # is 4u7z-9j460-aa. Hope you find your problem.

Code 402 0n 2001 mazda tribute


A code P0402 most likely means one or more things has happened. The DPFE (differential pressure) sensor is faulty and needs to be replaced, there is a blockage in the EGR (most likely carbon buildup) or the EGR valve may not be opening due to a lack of vaccuum.
