1991 Mazda MPV Engine trouble light on

For vehicles 1996 and newer, local part stores such as AutoZone can do this operation for you free of charge. However, for vehicles released before 1996, you will have to purchase a diagnostic scanner that is designed for your vehicle.


Operation of the diagnostic scanning tools are very simple. The included instruction manuals are very easy to understand and follow along with as well. Once codes are retrieved, you will have the option of deleting the codes from the computer by using the scanner.


Post your engine codes and we can help with repairs.

Hello, Here is how to retrieve codes..... 1.Warm engine to operating temperature and turn ignition "OFF." 2.Ground the test connector (1 pin wire) with a jumper wire. NOTE: Test connector is located next to the check connector in the engine compartment near the left side strut tower. 3.Turn the ignition switch to the ON position. 4.If MIL illuminates, goes off, and stays off no codes are present. 5.If MIL illuminates, goes off, and then starts flashing, codes are present. 6.Count the flashes to determine the fault code.

Here are some Mazda Codes 1 Ignition Pulse. 8 Air Flow Meter. 9 Water Thermo Sensor. 10 Intake Air Thermo Sensor (Air Flow Meter). 12 Throttle Sensor. 14 Atmospheric Pressure Sensor. 15 Oxygen Sensor. 17 Feedback System. 25 Solenoid Valve (PRC). 26 Solenoid Valve (Purge Control) . 28 Solenoid Valve (EGR). 34 Idle Speed Control Valve (ISC). .
