Mazda Tribute & Ford Escape V6 Common Problems

Mazda Tribute/Ford Escape V6 common problems

As this model has been in Australia for over 10 years, we are now getting many tech calls relating to the Mazda Tribute/Ford Escape V6. Listed below are some common problems and remedies.

First Symptom: Ignition Coils (COP)

Engine check light illuminated, logging trouble code P0301, P0302, P0303, P0304, P0305, P0306 (Cylinder misfire codes).
Customer may also complain of driveability issues such as, engine runs rough, lack of power, poor fuel economy, rough idle, etc.


The most common fault we have found is the failure of ignition coils (COP- coil on plug).
This coil failure may be due to either the age of unit or premature failure as a result of air leaks causing coils to overload and oil leaks causing contamination of spark plug tubes.
If code P0300 (random misfire) is logged, there may be an air leak usually caused by the inlet manifold and/or plenum chamber gaskets.

(A smoke machine is recommended for this task) Call CoolDrive and enquire about its OTC Smoke Machines that are available

QLD (07) 3481 5066 or

NSW (02) 9897 9922

Second Symptom: DFPE Sensor (Differential Pressure Feedback EGR)

Engine check light illuminated, commonly logging trouble code P0401 (Exhaust Gas Recirculation insufficient flow detected) and P1401 (DFPE sensor signal high).
Customer may also complain of driveability issues, such as pinging (knock), surging, lack of power, poor fuel economy, rough idle, etc.


The DPFE sensor monitors function of the EGR valve by measuring flow changes in the exhaust gas recirculation (EGR) system. The sensor is exposed to the elements of harsh exhaust gas and when the sensor fails the Check Engine Light will illuminate.
Check the hoses at the DPFE sensor are not leaking or damaged and the EGR valve ports are free of restriction.


Replace the DPFE sensor, available through CoolDrive Tech Repair Centres
