20 Most Recent 1995 Mazda Millenia Questions & Answers

You need the OBD1 engine control system (known as "MECS") scanned for fault codes.

Try a full reset. Disconnect the car battery for about an hour. Reconnect the battery then try it again. Doing a full reset should reprogram the EEC to go back to factory settings. It worked doing this on my Ford. I would suggest it will work on a Mazda.

Scanners aren't oracles and fault codes aren't gospel. Codes provide strong clues that mostly provide satisfaction but not always. When a code pops up it can mean a circuit has been snagged rather than just a sensor and the circuit includes the wiring, connections and part of the ECU. The results of a scanner should always be verified by independent testing of the component, multimeter checks of the circuitry and examining live data. A back to basics approach is best rather than jumping in with the scanner. Bad injector spray patterns can cause a number of "unrelated" codes to pop up, for instance...

P1195 refers to the map sensor, not the egr solenoid. It could be a bad map sensor, bad wiring, or possibly a bad or loose vacuum hose. P1522 refers to the air control flap actuator on the intake manifold. You can see about yhat at the link below. https://www.autocodes.com/p1522_mazda.html

I think you can change a good tail light for your car.

No, u can only find that out with the scanned code. The other way is to find out is the way it drives or starts.

If the car has individual coil packs (one for each cylinder) it indicates that one of the coils is bad causing the car to misfire.

First is all always write down the codes you have present, it helps in closing down on the problem. I am assuming you have a 95 Mazda Milleinia 1. Start and run the engine and monitor the oxygen sensor signals and see if this sensor has bad readings still. Check for an open or shorted wire between the sensor and the Engine Control Module (ECM) if the signal is dropping out. 2. Listen for an exhaust leak in the area of the oxygen sensor, the leak could allow oxygen in to the exhaust and skew the sensor readings. 3. Inspect the ECM and ECM connector for signs of something that has been spilled on the ECM. Is the engine idling too high or too low then check this:- 1. Unplug the idle air control valve and turn the air bypass screw in to see if it will idle down. If it will idle down, adjust the idle speed to around 500 RPM's and then plug the idle air control valve back in. 2. If it still idles high, remove the air boot from the throttle body, block the air bypass ports with duct tape, hook the air boot back on and start it. This should make it not idle at all or just barley idle. If it does, the problem is in the idle air control valve. 3. If blocking the air ports doesn't cause it to idle down, the throttle plate must be sticking open. Clean the throttle plate really good and back the throttle stop screw off and then see if it idles down. 4. Verify the coolant level is not low and that coolant is circulating through the idle air control valve. Tech Tips: This idle air control valve is two valves in one. It is a fast idle thermo valve on one side and a duty cycle idle air control valve on the other. I’m happy to assist further over the phone at https://www.6ya.com/expert/uttamjeet_2f3adc18600f8ede

The freeze plugs has a slow leaking.

Do a coolant system pressure test to locate the source of the leak.

follow this u-tube link as is easier to show you than me tpye the procedure Mazda Millenia Checking Your Automatic Transmission Fluid

code p0302 refers to cylinder 2 --misfire detected ===causes--engine mechanical fault--wiring---ignition/ fuel system---injector--ECT/MAF sensor--ECM move no 2 injector to another cylinder and see if the miss moves . If so replace the injector . IF not check the wiring to no2 injector. Check the HT lead to no plug and replace it the connections are loose.

u must be using wrong plugs< make shure u are using irredium plugs
