    The 2002 Mazda MPV is in pristine condition with only 38k miles on it..... No rust or dirt of any kind on the wire harness or connector where the O2 sensor wires connect. An other ideas?

Put some penetrating oil on them and let it soak overnight. This will break up the rust and other build up. Make sure that it is penetrating oil, you can get it at any automotive store.

P2195 and p2197 are the 2 codes that pop up what are they and what do i need to change? mazdz mpv 2005 3.0 li


P2195 and P2197 means that the O2 sensors on each bank are seeing WAY too much oxygen in the exhaust gas. In normal operation the signal from the O2 sensors should swing back and forth between rich and lean... Your sensors are locked on lean. Replace both O2 sensor.

Hope helps (remember rated this).

Where is the bank 2 o2 sensor located on a 2004 Mazda MPV LX


bank 2 is the cylinder in the front of the engine compartment near the radiator, the O2 is either in the exhaust manifold of the bank or in the exhaust pipe off the manifold, round about the size of a jumbo magic marker, you need a special O2 sensor socket to remove it in some cases, if it is in the open then a 7/8 open end wrench will work.

I am getting a P0031, P1512, & P0421 code


P0031 - most likely pointing to a failed O2 sensor (bank 1 sensor 1 is located before the catalytic converter)

P0421 - failed catalytic converter or a failed O2 sensor

P1512 - intake manifold shutter valve is stuck - may be caused by the O2 sensor, but may not

I recommend replacing your O2 sensor first and see what happens

Replaced o2 sensosor, SES light back on


If he used a "universal" O2 sensor, you could have a wiring problem. I had the exact same behavior on a Mazda MPV. The universal O2 sensors have to be crimped to the old sensor connector, which can cause problems. You can check the wiring closely, or insist that he use an OEM sensor, which will have the proper connector attached.

O2 sensor


There should be two O2 sensors. If you look inbetween the engine and radiator following the exhaust manifold down to the exhaust pipe you should run into the 1st O2 sensor, following the pipe down stream under the vehical towards the catalytic converter you should find the second O2 sensor. The 1st O2 should be easy but the 2nd might be difficult depending on your abilities. Coils will depend on 4 or 6 cyls, 1 for each cyl. Repair man, go to, pep boys, napa, auto zone, advanced auto parts to name a few.
