The cooling fan module can fail causing the fan to either run constantly, or not operate at all. If the fan runs continuously, the engine may not warm up properly, and if the fan does not run, the engine may overheat. Mazda has a voluntary recall on model years 2002-2003 to address this concern.

Defective or worn out ignition coils can cause engine misfires and Check Engine Light illumination. If the problem is severe enough engine performance will suffer and the Check Engine light will flash on and off.
If the engine cranks but won't start, the fault may be internal to the distributor . Diagnosis will show no spark and trouble codes for the crankshaft position sensor (CKP) or the camshaft position sensor (CMP). Our technicians recommend replacement of the complete distributor assembly if these conditions occur.
The PCV valve can crack open and create a vacuum leak and lean fuel mixture, which can result in surging and/or engine misfires .
Some MPV's may experience Check Engine light illumination with specific trouble codes stored in memory. If the two codes are stored, there are updated parts for the evaporative emissions (EVAP) system , and updated software for the Powertrain Control Module (PCM) .
