Mazda Millenia

The codes P0421 and P0431 indicate that the catalytic converter's efficiency is below the required threshold for Bank 1 and Bank 2 of your 2002 Mazda Millenia. This usually suggests that the catalytic converters may be failing, or there could be issues with the oxygen sensors that monitor their performance. It's advisable to inspect the exhaust system, oxygen sensors, and the condition of the catalytic converters to determine the root cause of the problem. Addressing these issues is crucial to maintaining optimal engine performance and compliance with emissions standards.

To remove the engine from a 1996 Mazda Millenia, first disconnect the battery and drain the engine oil and coolant. Next, remove the necessary components such as the air intake, exhaust, and any accessory belts. Support the engine with a hoist, detach the engine mounts, and then disconnect wiring harnesses and hoses. Finally, lift the engine out of the engine bay carefully.

To replace the timing belt cover on a Mazda Millenia, first ensure the engine is cool and disconnect the battery. Remove any obstructions, such as the drive belts and any components blocking access to the timing belt cover. Unscrew the bolts securing the cover and carefully remove it, taking care not to damage the gasket. After replacing the cover with a new gasket, reassemble the components in reverse order and double-check that everything is securely fastened before reconnecting the battery.

In most cases the crank pulley bolts to the balancer so the crank pulley would not be the same as the harmonic balancer.

Tap on your 1998 Mazda brake rotors with a hammer or mallet until they become loose. The brake rotors will simply slide off.

it is connected to the back of the push button panel. you have to remove the portion of the dash that the push buttons are in to access the amp. there are 2 screws, one each on either side of the steering column. pop off the black plastic bezels, and pop off the dash lite rheostat. underneath are the screws. then, gently pry off the dash part. i start at the glovebox. you will then have to disconnect the wiring harness' to the a/c amplifier. all the controls/amp are then accessible from the back

Question: Is the car running or stalled? If stalled try starting it. If the key won't turn to start it or move to another position, try to move your steering wheel out of the locked position. Somtimes when there is resistance, or pressure against the lock you will not be able to turn the key - on or off. Question: Are you stopped on an incline? If so, the gear may not allow you to move to park (or out of park sometimes) if there is positive resistance on the transmission. This would prevent you from putting in park.

DISCONNECT NEG LEAD FROM BATTERY. After removing main fuse block cover, remove smaller cover with holes that allow viewing fuses. It's held on by clips around fuse block. The entire fuse block can be unattached from the wheel well by removing a couple of obvious screws. This allows access to lower part of fuse (white fuse, 120A). Don't pull too hard on block, you'll disconnect something else. Here's the trick: it's a regular blade-type fuse, but the blades have screws thru them. Follow the heavy cables running to bottom of fuse block to main fuse, one screw per blade. Remove screws & pull fuse straight out. It's tight, but it'll come straight out.

The room fuse in my '99 626 protects _ignition-off_ function of the power door locks, headlights, and some other functions, IIRC including all operation of the radio. For example, if the Room fuse is blown, my power locks work, but only with the ignition switch on. Doc

tcs is part of a separate control unit(tcm) attached to the main pcm. when there is a problem with abv, the pcm stops communicating with tcm(transmission control module), and the car is put in "limp home" mode(tcs off/tcs lites illuminate, car will not rev above 2500). quite common in the 2.3, generally, a vacuum line problem. you probably also have codes p1525/26 and/or 1540. first fix the vacuum lines, change out the tees and the lines(about 21 feet), next would be the vacuum/vent solenoids in the back of the engine. one or both of those generally fixes this problem

Change your cabin air filter first. If it persists, there are chemicals available to clean the evaporator core area of the A/C system through auto parts stores.

Also, you can spray a mildew-killing deodorizer ( Lysol makes a "Soft Powder" scent that's not too unpleasant) into the fresh air intake while car & A/C are running. A/C should be on "fresh air" setting. Spray until scent is noticable inside car. My intakes are just ahead of windshield, on passenger side. Open hood & you'll see them. Drive as usual w/ A/C on, maybe windows down for a few miles. Repeat as needed.
