2008 Mazda Tribute Hybrid ProblemsDamaged PCM Wires May Cause Engine Misfires
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.
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.
