P2195 & 97 is a lean condition reported by both O2
on right side

The pcm drove the fuel trim lean to correct for a over
rich condition on right bank only due to a leaking fuel
injector most likely

That is a common problem on an expedition with 5.4

I have seen people find & replace the bad injector
I would mail all of them away to be ultra-sonicly cleaned
& flow tested if it were mine

If you have a professional scan tool or software you woulod
see the issue on fuel trim.

The MAF is common to both banks & you only have an issue
on the right side so the MAF is okey

Your plugs should give some indication of the bad injector
if that is the case

Need details on brakes!!

I recently had problems with my 2005 Mazda MPV stalling. I came to this great site and changed the IAC and it stopped stalling. But 2 days later my check engine light came on. The codes are P2197 P2195...


The descriptions for your codes are:
P2197 - H02S (RF) signal stuck lean
P2195 - H02S (RF) signal stuck lean
P2187 - Fuel System too lean at idle
P0102 - MAF circuit low input

Essentially what's happening is that your MPV is running too lean when at idle. Too much air and not enough fuel. As you speed up - it forces more air into the system which alleviates the problem.

Examine your mass airflow sensor. It should be completely clean - no fuzzies on it at all. If so - purchase some mass airflow sensor cleaner to clean the sensor. ONLY USE THE PROPER CLEANER TO AVOID DAMAGING THE SENSOR. Disconnect the battery to reset the system and turn off check engine light.

Otherwise you will need a scan tool to look at the voltages being supplied to/from the PCM for each of the Heated Oxygen Sensors and the Mass Airflow Sensor to determine which part is creating the problem.

2004 mercury montery sputters when in idle , went to autozone got codes p2197,p2195,p0171,and p0174 have changed fuel filter and still continues.


Most likely a vacuum leak effecting the O2 Sensors

That is your 4 codes.

Have the Evap System checked also, for leaks

Fuel Filter--filters fuel,doesn't fix anything

P2197 p2187 p2177 p2195 p2179 p2189


P2197 - Oxygen Sensor Signal Biased/Stuck Lean Bank 2 Sensor 1
P2187 - System Too Lean At Idle Bank 1
P2177 - System Too Lean Off Idle Bank 1
P2195 - Oxygen Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1
P2179 - System Too Lean Off Idle Bank 2

I am not sure what your Mazda is, but from the sounds of it, both of your Oxygen Sensors are shot. Replace them both, or check for vacuum leaks. It may be a good time to inspect and replace the PCV Valve and PCV Valve hose, too.

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).
