SOURCE: 2001 mazda 626 es v6 oxygen sensor flamed up and caught fire

sulfur smell is excess fuel getting burned in the cat. convertor.

The o2 sensor itself may be bad... causing the ECM to get bad readings and send extra fuel that isnt burned during ignition.

Check the engine codes with an OBD reader, (even if the CEL is not lit) because the bulb may be out or missing.

If you get codes, ask the parts store or re-post here, and I can help you further.

SOURCE: 97 mazda 626 dx 2.0. manual shift, crank but won't

First check the spark plugs.

If your engine cranks normally but will not start because it has no spark, or it stalls and won't restart because it has no spark, the problem may be due to any of the following:

1) A bad pickup inside the distributor ,a stripped distributor drive gear (common problem with plastic distributor drive gears), broken, loose or corroded wires from the pickup to the ignition module or PCM.

2) A bad crankshaft position (CKP) sensor or broken, loose or corroded wires from the sensor to the PCM.

3) A bad ignition module or A bad ignition coil .

4) A bad rotor or distributor cap (cracks or carbon tracks that are allowing the spark to short to ground)

5) Faulty ignition switch.

------------

You can also do a test to confirm the problem .The procedure to do the test is as follows:---

If your engine has spark plug wires, disconnect one of the plug wires from a spark plug and place the end of the wire near a metal surface on the engine. Then insert a small Phillips screwdriver into the end of the wire (the plug boot), or a small bolt or nail to provide a conductive path. Then crank the engine and look for a spark to jump from the screwdriver, bolt or nail in the end of the plug wire to the engine. If you do not see a spark, there is an ignition problem.

OR-----------

If your engine has a coil-on-plug ignition system with no plug wires, In that case remove one of the coils from the spark plug and insert an old spark plug, a spark plug tester or a screwdriver into the end of the coil. Ground the spark plug or plug tester to the engine, then crank the engine and look for a spark. No spark indicates an ignition problem.

Possibilities to be checked in this problem are as follows:--


If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If NO voltage, then problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit).

But If there is NO voltage at the coil itself, then in that case the problem is on the supply side (the ignition switch or ignition wiring circuit).

But if the coil has voltage, then problem may be a bad high voltage output wire from the coil to the distributor, hairline cracks in the coil output tower, or cracks or carbon tracks inside the distributor cap or on the rotor.------Getting this all possibilities checked will point towards the exact faulty part which is to be replaced.

But if all this possibilities checked out ok,then yes its the ECU fault.Get the ECU checked and replaced.----------This should help.Thanks.Helpmech.

I have a 2000 mazda millenia s the battery keeps


you have 2 separate issues. one is a parasitic draw on the battery from an electrical component. not passing smog is an emissions related concern involving egr, oxygen sensors, catalytic converters, evaporative systems, and engine overall performance.

95 Mazda Millenia- P1195 & P1152 (P1151):


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...

95 Mazda Millenia- P1195 & P1522: I have already replaced the mass air flow sensor all but 2 O2 sensors, and I have replaced the selenoid for the EGR according to the P1195 code problem/solution i


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.

Where is the oxygen sensor? and is there more than one/


O2 sensor is after catalytic convertor and only one and most never goes bad, just needs cleaned.

I have a P1170, and a P1195 What are these two codes?


P1170 HO2S Bank 1 Sensor 1 Circuit Fixed (Bank 1 Sensor 1) The ECM (engine control module) is getting a low or no signal from the front oxygen sensor on bank #1. Possible bad sensor or open sensor circuit.
P1195 EGR Boost Sensor Circuit There is a problem with the EGR (exhaust gas recirculation) system. Possible plugged or restricted passage or sensor / sensor circuit problem.

Where is bank 2 sensor 1 oxygen sensor on a 2001 mazda milinia s


In a V6 or V8 engine the driver's side cylinders are one bank and the passenger side, the other bank. I would imagine "Bank 2" is the side without the the #1 cylinder on it. The sensor is screwed into the exaust manifold which is bolted to the cylinder head. "Sensor 1" denotes it from the downstream (post catalytic converter) sensor(s), which is referred to as "Sensor 2"

Hope helps.
