YOU possibly have a vacuum leak on bank 2 or a bad o2 sensor check all vacuum hoses and seals

MIL /CHECK eNGINE LIGHT


first make a tune-up to your car and clean de codes if the problem continues you need change the oxygen sensor

Hi, I have a VW EOS 2007, check eng light on, 008583 - Bank 1; System too Lean at Idle P2187 - 004 - - MIL ON, then, 004369 - Oxygen (Lambda) Sensor Regulation: Bank 1


The O2 sensor is most likely the issue. Also, try cleaning the Throttle Body Injector with cauberator cleaner or tbi injector. Build up within the TBI may be causing a gas deficiency which causes it to run lean. If that doesn't help, try running a higher octane fuel, about 93 octane minimum. This will causes ANY debree in the injectors to be cleared.

6troubles codes reportd;PO133N2 SENSOR CIRCUIT SLOW RESPONSE


Don't know the vehicle you have ,so if your
front or upstream oxygen sensors are over
100,000 miles, they need changing, on all
your vehicles ,front only, leave rear monitors
until the converters wear out at 12 years or so

Then you can diagnose what ever is left

You got slow & lean sensors
Their old & tired & lost their switching
ability

Google the codes & read up

Change Spark Plugs every 3 years
Clean MAF Sensor-CRC MAF Cleaner
New Air Filter

Please tell me what this means,,, po171 band 1 system too lean and po174 band 2 system too lean, thank you, jill


PO 171--is an O2 Sensor Code for a Lean Condition
on Bank 1 (right side exhaust)

PO 174 -- is an O2 Sensor Codes for a Lean Condition
on Bank 2 (left side exhaust)

You gave us no vehicle
You gave us no drivability issues or
vehicle history,nothing

If the O2's have 100,000 miles on them,change the (2)
closest to the engine. They are most likely worn out
& the switching times are too slow to control injector
pulse width & thus set a MIL Lamp (OBD2 Fault ) on
your dash

You can learn a lot on the internet if you put OBD2 in your
Search Engine (Internet Explorer,etc)

2003 Ford Ranger 4x4 extended cab- diagnostics checked and got these codes- P0171, P0174, P0300, P0316. Can you tell me what they mean?


P0171------ system too lean bank#1
Po174------ system too lean bank#2
For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
P0300---- Random/multiple cylinder misfire
P0316---- Cylinder misfire at start up---- first 100 revolutions.
On those 2 codes, you have to do some testing to find out why there is a misfire.
Possible causes:
dirty/malfunctioning injectors
weak coil pack
fowling spark plugs/wires
Low fuel pressure

Troble code P0170


Trouble Code: P0170 (3.4L V6 VIN V Auto)
Fuel System Too Rich or Too Lean (Bank 1) Print this code dataprint_icon_codes.gif Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
DTC P0100, P0101, P0110, P0115, P0120, P0121, P0130, P0133, P0136, P0135, P0136, P0141, P0153, P0155, P0201-206, P0300, P0301-P0306, P0401, P0402 and P0441 not set, engine running in closed loop at a stable engine speed, and the PCM detected the lean or rich fuel trim correction value was more than or less than a calibrated limit in memory.

Possible Causes:
  • Air leaks present in the exhaust manifold or exhaust pipes
  • Air being drawn in from leaks in engine gaskets or other seals
  • Base engine "mechanical" fault affecting one or more cylinders
  • Fuel control sensor is out of calibration (i.e., ECT, IAT or MAF)
  • Fuel delivery system supplying too much or too little fuel at idle or cruise (e.g., faulty fuel pump or dirty, restricted fuel filter)
  • One or more fuel injectors is dirty, leaking or stuck open/closed
  • HO2S element is contaminated, damaged or it has failed

2004 or 05 Jeep Wrangler dtc P2096 (Post catalyst fuel trim bank 1 to lean). It set the mil lamp and then reset it self. Pulled the code with a scanner and found 1 of 2 to be P2096 and 2of 2 to be P2096...


Here is more information about P2096
P2096-DOWN STREAM FUEL TRIM LEAN BANK 1

WHEN MONITORED 
With the engine running in closed loop mode, the ambient/battery temperature above (-7°C) 20°F , altitude below 8500 ft and fuel level greater than 15%.

SET CONDITION 
If the PCM multiplies short term compensation by long term adaptive and a certain percentage is exceeded for two trips, a freeze frame is stored, the MIL illuminates and a trouble code is stored. Two Trip Fault. Three good trips to turn off the MIL.

Here are some possible casuses:
Exhaust leak
Engine mechanical problem
02 sensor
02 signal circut
02 return circut
Fuel contamination

Good luck and hope this helps.

Codes p1153 -p1140 -p1133-p0174


P0174 Basically this means that an O2 sensor in bank 2 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 2 is generally the side of the engine that doesn't have cylinder #1.
P0140 Basically this means the an O2 sensor in Bank 1 detected a lean condition, same as mentioned above. Bank 1 is the side where cylinder #1 is.
In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling.

P1133 and P1153 indicate that the HO25 Sensor has gone bad. There the O2 sensor to the left and right bank at the exhaust manifold. When the engine first start's the PCM runs on a open loop and ignores the O2 readings till it reaches it's operating temperature. Once the operating temperature has been reached the diagnostic will only run once per ignition cycle and if the PCM detects a lesser then specified value, a DTC of P1133 or P1153 will come up.
Once the problem has been repaired, after 3 start cycle will reset the MIL light. If the O2 is just dirty and slow to heat up try cycling the ignition start 3 times and the light should go off if the O2 sensor does not fail.
Try cleaning the MAF first and see if the light comes off after a few ignition cycle, If the service light is still on you can always have Auto Zone clear the DTC codes and see if it comes back which then check the left and right bank wire harness to the O2 sensors. 
Good luck and hope this helps, keep me posted.
