The DPFE (differential pressure feedback EGR) sensor tends to fail. The DPFE sensor monitors function of the EGR valve by measuring pressure changes in the exhaust gas recirculation (EGR) system. Symptoms of a failing DPFE sensor are hesitation or stumbling when driving along with illumination of the Check Engine Light.

2003 Mazda Tribute Problems
If the engine is misfiring, it may be caused by a damaged wire(s) which connect the fuel injectors to the Powertrain Control Module (PCM). The damaged wire(s) can be repaired or the emission wire harness replaced. A misfire can result in a loss of engine performance and illumination of the Check Engine Light.
If the engine stalls after a cold start (the vehicle has been parked for a while), the idle air control (IAC) valve may be sticking. It may be fouled with carbon buildup. If cleaning the valve does not solve the problem, replacement will be needed.

RepairPal Expert Overview:
Mazda Tribute models equipped with a V6 engine are being recalled because inadequate clearance between the engine cover and the speed control cable connector could result in a stuck throttle when the accelerator pedal is fully or almost fully depressed. This risk exists regardless of whether or not the speed control (cruise control) is used.
A stuck throttle may result in very high vehicle speeds and make it difficult to stop or slow the vehicle, which could result in a crash. Dealers will correct this concern by increasing the engine cover clearance. Remedy parts are expected to be available in mid-August. Until then, dealers will disconnect the speed control cable as an interim remedy if parts are not available at the time of an owner's service appointment. The Mazda recall number is 6812G.

2003 Mazda Tribute Reviews
Had problems with the drivers seat beat. The light stayed on. Took it to the dealership, they replaced seat beat straps.Did not work. Problem never solved
Had to have it idle up. Always cutting off.
I bought my Mazda Tribute new (48MILES. It has been the best vehicle I have ever owned!! Just now starting to have engine light come on and off and engine is cutting back. Any ideas? I have replaced the fuel pump & new battery.
Nothing but problems, alternator 2 times, intake manifold gasket, brakes all the time, transmission, brake booster all before 100k. There is more can't recall off the top of my head. Worst car ever!!!
2003-Purchased new. No problems. I keep all my fluids clean and fresh which I feel is a key.
I have had to repeatedly take my Tribute in for the airbag sensors that keep failing on both sides of the vehicle. If you google that you will see more people with the same problem. Mazda still can't figure out the solution. As soon as they change the sensors, a week later quit again. Now I'm riding around with no airbags due to this problem. Also, some nuts behind the wheel rusted off and caused my brakes not to work correctly until replaced.
