Known Problems

If the Check Engine Light comes on, and diagnosis finds a trouble code, or codes, for misfires, it might be caused by insufficient valve clearance for the affected cylinder. The valve clearances should be inspected and adjusted where needed.

The PCV valve can crack open and create a vacuum leak and lean fuel mixture, which can result in surging and/or engine misfires.

The engine may fail to start due to an electrically shorted sensor. Some of the sensors may internally short and not blow any fuses. A technician may find no spark and no operation of the fuel injectors in the diagnosis. One way a technician may isolate the defective sensor is by disconnecting sensors one by one to see if the engine starts.

The passages for the Exhaust Gas Recirculation (EGR) system can become restricted or clogged causing the Check Engine Light to illuminate. The EGR valve will need to be inspected and the passages cleaned.

The AC compressor may fail causing the AC system to blow warm air, smoke may also appear from the engine. A failed AC compressor will require replacement. Mazda has extended the warranty on these compressors to 5 year or 60K mikes. If these conditions are noted our technicians recommend to turn the AC system off and have it inspected as soon as possible.

A lack of power may develop due to a failed turbocharger. Failed turbochargers will require replacement to restore engine power.

A vibration felt at 55 mph may not be a tire problem. Mazda has revised motor mounts available which may help remedy this problem.
