I was getting a P2195 (O2 sensor stuck).
After following this tread and others I checked the PVC and cleaned it.
Then removed and checked the ERG with a vacuum.
Now all is well. Not sure what it was. Engine runs smooth and does not
set code. I too first replaced the O2 sensor. What a waste.

SOURCE: Check Engine Light - O2 Sensor - bank 1 running lean

you should have three oxygen sensors on your car, one for each bank of three cylinders; should be towards the Y pipe on each exhaust manifold. Additionally you should have one on the exhaust pipe before the cadilitic converter.

P2196 O2 Sensor Signal Biased/Stuck Rich (Bank 2 Sensor 1) Code

1 Answer

Can i use a store bought digital multimeter to determine if there is a possible short to signal circuit with a P2196 (Bank 1 Sensor 1) causing the rich stuck in my car?


My source says code 2196 means the signal coming from the O2 sensor is stuck on rich.
The sensor is supposed to switch back and forth from lean to rich to lean as the computer controls injector "on" time. If the sensor signal stays rich, in most cases there is a leaking injector, or the sensor is faulty. I doubt a short to anything would be involved.
The sensor generates a small ac voltage between zero and one volt. Less than 1/2 volt is lean and more than 1/2 volt is rich. There is a heater in the sensor that could short to the signal wire, but then you should have a code for the heater circuit too.
You can remove the sensor and check for excessive carbon buildup from a rich fuel mixture, or go ahead and replace it and see what happens. A repair shop would be able to check exhaust gas output to find out if its the sensor or a leaking injector.

I have codes p0202 p0203 p2196, when i go to ford dealer they told me i need a new engine because cylinder #2 is low in compression only 17%, but the report they gave me doesn't show the code p2196.


Code P2196 indicates a rich condition. My guess is that raw fuel is passing through the non-firing cylinders is the cause of the rich condition and will probably be corrected when the engine is repaired. You can't chase a rich condition when you have a poor running engine.

I have five codes P2237 P2196 P2271 P0030 P0171 and a P2237 pending code on a 2005 elantra.The car runs poorly, bad gas mileage, sluggish with the check engine light on.Are all O2 sensors bad or maybe the...


P2237 P2196 P2271 P0030 P0171

These are all O2 sensor trouble codes, except P0171 which is a fuel trim code,

You have a bad 02 sensor - up stream - Bank 1 Sensor 1.

Replace it, then road test. The engine computer has a 'default' fuel trim it uses when an O2 sensor fails so it can protect the catalytic converter. If this hasn't been going on too long, good chance simply replacing the O2 sensor will remedy your problem.

Sounds like you have some EGR ports clogged up, remove the intake and look at the egr ports all but
