SOURCE: little power cat converter red hot locate massive air flow sensor

the catalytic converter is clogged,needs to be relaced or other exhaust restriction check pipes and muffler, disconnect after the catalytic converter see if cat still glows

SOURCE: check engine light

It might but what exactly are the codes. Before you change the Mass air flow sensor, try cleaning it first with a can of mass flow cleaner.
If your running a oil K&N filter, there could be some oil residue on the sensor. Start with that and change the filter or clean it if it's a K&N.
The O2 sensor's could be bad also, you really need the code's to be sure what sensor is giving you the faulty signal.
Good luck and hope this helps.

SOURCE: Check engine light was on. OBD II scan said both

The pre cat sensors running lean does not mean they need to be replaced. They are are detecting a symptom. You need to know why.

If you are using a basic scantool (code only) you need to look up the P0000 code.
I thought this an odd code. I looked it up in my Autotap unit and it does not exist. The lowest # P (powertrain) code I have listed is P0016.

A regular scan tool, won't scan transmission or body codes, mu Auto tap doesn't either. You need a Tech 2 from the dealer for transmission codes.

First some history. The first O2 sensor was introduced in 1976 on a Volvo. California vehicles got them next in 1980, then federal emission laws made O2 sensors virtually mandatory on all cars and light trucks built since 1981. And now that OBD-II regulations are here (1996 and newer vehicles), most vehicles now have multiple O2 sensors, some as many as four!
The O2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust. The signal from the O2 sensor tells the computer if the fuel mixture is burning rich (less oxygen) or lean (more oxygen).
A lot of factors affect the richness or leanness of the fuel mixture, including air temperature, engine coolant temperature, barometric pressure, throttle position, air flow and engine load. Other sensors monitor these factors too, but the O2 sensor is the master monitor for what's happening with the fuel mixture. Problems with the O2 sensor can throw the whole system out of whack.
The computer uses the oxygen sensor's input to fine tune the fuel mixture for the best balance of power, economy and emissions. The engineering term for this type of operation is "closed loop" because the computer is using the O2 sensor's input to adjust the fuel mixture. The result is a constant flip-flop back and forth from rich to lean which helps the catalytic converter operate at its best and keeps the average fuel mixture in proper balance to minimize emissions. It's a complicated setup but it works.
If no signal is received from the O2 sensor, like when a cold engine is first started (more on that in a minute) or the 02 sensor fails, the computer orders a steady, rich fuel mixture. This is referred to as "open loop" operation because no input is used from the O2 sensor to fine tune the fuel mixture. If the engine fails to go into closed loop when the O2 sensor reaches operating temperature, or drops out of closed loop because the O2 sensor's signal is lost, the engine will run too rich causing an increase in fuel consumption and emissions. As you might have guessed, that will set a code and turn on your check engine light.
How does it work? The O2 sensor produces a voltage once it gets hot. The sensor compares how much oxygen is in the exhaust to the oxygen in outside air. The greater the difference, the higher the voltage reading.
If you ever replace an O2 sensor (and if you're a DIY'er this is something you will do eventually), its important to remember that the O2 sensor needs to "breath" outside air to work. So don't put any grease on the sensor because it could block this air flow.
An oxygen sensor will typically generate up to about 0.9 volts when the fuel mixture is rich and there is little unburned oxygen left in the exhaust. When the mixture is lean, the sensor's output voltage will drop down to about 0.1 volts. When the air/fuel mixture is balanced or at the equilibrium point of about 14.7 to 1, the sensor will read around 0.45 volts.
When the computer reads a rich signal from the O2 sensor it leans the fuel mixture to reduce the sensor's reading. When the O2 sensor reading goes lean the computer reverses again making the fuel mixture go rich. This constant flip-flopping back and forth of the fuel mixture occurs anywhere from 2 to 7 times a second at 2500 rpm on OBDII vehicles, depending on what type of fuel injection system they have.
The oxygen sensor must be hot (about 600 degrees or higher) before it will start to generate a voltage signal. Many oxygen sensors have a small heating element inside to help them reach operating temperature more quickly.
Ok – that was a lot of info on what they do and how they work. The next thing to know is that trouble codes relating to O2 sensors are very common. But you really need investigate further before replacing an O2 sensor just because you got that trouble code. Armed with the information above on how often the O2 sensor "flips" back and forth and AutoTap or another scantool that allows you to monitor O2 sensor voltage, you can be certain whether the O2 sensor itself is really the problem. These sensors can be pricey, so don't just replace them the first time you see that trouble code!

The O2 sensors are expensive, diagnose what really is going on.

Why is there an anti-pollution fault on first start followed by management light on?


It's not unusual for 207s to show the anti-pollution warning randomly. In my experience it isn't significant and you just learn to live with it, but as yours is consistently showing at start up accompanied with the engine management light, it maybe something more serious. If the car appears to be driving okay, then I would be inclined to ignore it, if not, you will have to have a Puegeot dealer put it on their computer diagnostic machine - pricey !

207s have a bad reputation for random fault indications as a whole (Google it), some of which seem to be ambient temperature related - my father's 207 randomly shows the air bag light on very hot days but this goes away after a few start/stop cycles and a drop in temperatures. Fortunately, his MOT is due in March so when it goes for an MOT the light is always off - air bag fault indication showing is now an MOT failure.
Some people wouldn't be happy driving with an air bag indication, or any other fault indication, showing even for a short period of time, so this is a personal decision as to what you do about it.

2000 Nissan mis firing,, code reader shows codes: 0430; 0305; and 1320. Assuming its bank 2 cat convertor. Is this where i should start???


430 is Oxygen sensor

0305 is misfire on cylinder 5

1320 is ignition coil.

The ignition coil is causing the misfire. That is causing rich mixture which could case the oxygen sensor issue. You need to work from the ignition issue to the sensor. The reason is if you replace the cat and the engine is running rich it will heat the cat up to the point that the car might catch fire. Oxygen sensors are also prone to fail after about 60 thousand miles.

Why does my peugot 206cc 2litre backfire when cold starting


Have it scanned for error code. Idle Air system may foul up. Coolant temperature sensor giving wrong readings will confuse the ECU. It may use 'warm' setting for cold starting, thus fuel would be lean. Ideally it should use 'cold' setting which provides richer air/fuel mixture.

hi ,
i'm thinking that you should get the computor scanned as the fault sounds like the oxygen sensor has failed, or the throttle body sensor is going into the cold start mode and flooding the engine, either way you won't know until a techy plugs in a scan tool.

My peugoet 206cc engine just cut out while driving home and now when I try start the car, the start works but the engine won't turn. The autodiagnostic light is also on. Please help!!


as starter is having no problem.
check for fuel;

check for air ventillation .lack of oxygen stops the engine.your air vent must be clogged.check it .it is in between air drum and engine.

Mis-firing, i've changed plugs and leads but engine is still not running proberly


Hello,It's normal for the cat to get hot - given they've replaced everything (just about) that could cause your problem - they have not looked at the injectors and O2 sensors. If you had something burning in the engine bay it was most likely electrical and you should look for burnt wires. You probably have a short in the ignition system or fuel injector wire harness. It's nearly impossible to diagnose a problem like this without having the car first hand. It must be throwing check engine light codes

Thanks
