2006 mustang came up with the engine warning code P2195 for the O2 sensor, what is this.

I don't know what you want or how you want to move forward with this issue. Give me an idea how you want to proceed and what additional diagnostic information you want. I am forwarding code information and possible causes. Let me know if you need anything else. Good Luck. Potential causes of a P2195 code include: Oxygen (O2) or A/F ratio sensor or sensor heater malfunction Open or short in O2 sensor circuit (wiring, harness) Fuel pressure or fuel injector problem Faulty PCM Intake air or engine vacuum leaks Faulty fuel injector(s) Fuel pressure too high or too low PCV system leak/fault A/F sensor relay faulty MAF sensor malfunction ECT sensor malfunction Fuel pressure too low Fuel leak Air suction in air intake system

P2195 is an OBD-II generic code for the engine control module (ECM) detecting the O2 sensor signal stuck lean for bank 1 sensor 1. The engine has tried to lean out a rich condition and failed.
Potential causes of a P2195 code include:
-Oxygen (O2) or A/F ratio sensor or sensor heater malfunction
-Open or short in O2 sensor circuit (wiring, harness)
-Fuel pressure or fuel injector problem
-Faulty PCM Intake air or engine vacuum leaks
-Faulty fuel injector(s)
-Fuel pressure too high or too low
-PCV system leak/fault
-A/F sensor relay faulty
-MAF sensor malfunction
-ECT sensor malfunction
-Fuel pressure too low
-Fuel leak Air suction in air intake system

Its always a good idea to double check codes especially with sensors, if its the heater circut replace o2 if its out of range reset and see if returns

P0303 Code - Cylinder #3 Misfire
P0110 DTC - IAT Circuit Malfunction
P2195 O2 Sensor Signal Biased/Stuck Lean (Bank 1 Sensor 1) Code
Potential causes of a P2195 code include:
p2195
p219521

• Oxygen (O2) or A/F ratio sensor or sensor heater malfunction
• Open or short in O2 sensor circuit (wiring, harness)
• Fuel pressure or fuel injector problem
• Faulty PCM
• Intake air or engine vacuum leaks
• Faulty fuel injector(s)
• Fuel pressure too high or too low
• PCV system leak/fault
• A/F sensor relay faulty
• MAF sensor malfunction
• ECT sensor malfunction
• Fuel pressure too low
• Fuel leak
• Air suction in air intake system
• A code P0303 may mean that one or more of the following has happened:
  

• Faulty spark plug or wire
• Faulty coil (pack)
• Faulty oxygen sensor(s)
• Faulty fuel injector
• Burned exhaust valve
• Faulty catalytic converter(s)
• Running out of fuel
• Poor compression
• Defective computer
• Potential causes of the P0110 DTC include:
  
• 
  po110
  • IAT sensor shifted out of airflow
  • Bad IAT sensor
  • Shorted to ground or open on signal circuit to IAT
  • Open in ground circuit to IAT
  • Poor connection at IAT (backed out terminals, broken connector locks, etc.)
  • Bad PCM

You obviously know nothing about todays
technology or codes

If had of Googled the code, you would see
it has to do with an Oxygen Sensor

Vehicles have no way to know what fuel your putting in them

P0132 FORD - O2 Sensor Circuit High Voltage Bank 1 Sensor 1http://engine-codes.com/p0132_ford.htmlForum CodePossible causes- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Front Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks
P2195 - O2 Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1

P2196 - O2 Sensor Signal Biased/Stuck Rich Bank 1 Sensor 1

I have the same problem on my 2006 mazda5. I go a new O2 sensor. Now I get p0131 and p2096 codes

p2195
02 sensor signal stuck lean bank 1, sensor 1
p2197
o2 sensor signal stuck lean bank 2, sensor1

i beleave this will be the sensor before the catalytic converter

In the exhaust manifold on the firewall side. Its not a o2 sensor. Its a AF sensor.(air fuel ratio sensor)
