SOURCE: location of O2 sensor in bank 2, 99 5.4 expedition, running lean

I have a ford 2003 windstar that was running very rough when cold and almost stalling. engine light came on. went to autozone and they read the codes for free and told me it was running lean on Bank 2 also. i came home searched for the O2 front sensors online using the info autozone gave me. there are 2 front sensors on my car that need to be replaced at the same time. look for ones that have a direct plug in and don't need wire splicing. the ones without the wiring harness are cheaper but more of a pain, i think.
they were fairly easy to replace. getting access with the wrench was the worst. reset the light by disconnecting the battery for a few minutes. seems fine now and the light hasn't come back on.

sounds like a dirty mass air flow sensor.if you have in deed replaced it i would check the voltage going to the sensor.perhaps its a faulty connection between the power controle module and the sensor socket.if that dosent work i have a few more tricks to try get back to me and i will help further. poppinwheelies@sbcglobal.net

SOURCE: 2002 Pontac Grand Prix GTP P0171 code engine stumbling at times

Bank 1 is the frt side exhaust manifold (did they say bank 1 sensor 1?),you can start by replacing that sensor,i would check the intake for leaks ,the gm 6cly. are known for bad intake gaskets,you will see oil coming out form the frt or rear of the intake,also check your atifreeze overflow bottle for bronwish sludge,which means that the oil is mixing with the antifreeze.A leaking intake could cause that lean condition.

Difference between Air fuel ration sensor to O2 sensor?


usually an O2 code is 3 digits and not this type of code. if it has an mass air flow sensor(MAF) it could be it. I would start with checking the MAF readings then the O2 readings. OBD 2 codes are emission regulated so no matter what car it is the codes represent the same problem.

Codes P2270& P2272 after oil change check engine light on drove under 100 miles both O2 sensors bad .Could shop have caused this somehow??? Maybe banging them or something ?


make sure they are plugged in tight Definition of Diagnostic Trouble Code P2270 Category: Powertrain Definition: O2 Sensor Signal Biased/Stuck Lean Bank 1 Sensor 2Note: This definition of P2270 is applied to all manufacturers

P2270 - O2 Sensor Signal Biased/Stuck Lean Bank 1 Sensor 2 Comments ' Add Yours
Possible causes
- Faulty Rear Heated Oxygen Sensor Bank 1
- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Exhaust gas leaks Help with this
When is the code detected?
The Powertrain Control Module (PCM) detected the HO2S12 sensor has reported a lean condition for an extended period during an intrusive test
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust
P2270 Description
The Powertrain Control Module (PCM) supplies a voltage of about 450 mV between the HO2S high and low signal circuits. The oxygen sensor varies the voltage over a range from about 1,000 mV when the exhaust is rich, down through about 10 mV when the exhaust is lean.
The PCM monitors and stores the heated oxygen sensor (HO2S) voltage information. The PCMevaluates the HO2S voltage samples in order to determine the amount of time the HO2S voltage was out of range. The PCM compares the stored HO2S voltage samples taken within each sample period and determines if majority of the samples are out of the operating range.

Check engine light is on and i got error code p1133. what is that?


Faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1
- Vacuum leak
- Faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 harness is open or shorted
- Faulty Heated Oxygen Sensor (HO2S) Bank 1 Sensor 1 circuit poor electrical connection

The Powertrain Control Module (PCM) monitors the Heated Oxygen Sensor (HO2S) activity for 90 seconds after closed loop operation has begun. The PCM determines if the front HO2S is functioning properly by counting the number of HO2S-1 Lean/Rich (L/R) and Rich/Lean (R/L) switches.

If the Powertrain Control Module (PCM) determines that the front HO2S did not switch enough times, the PCM will set the P1133 code.

replace the o2 sensor

i think the check engine light caused by oxygen sensors,due to little misfire detected , fuel system ,bank 1 and bank 2 lean and rich mixtures..

Ok i got a 2002 saturn vue..code was saying bank 1 bank 2 running lean..the vue runs perfect ,sometime at park it would idle hi.anyways i have replaced the mass air flow unit..turn off light,comes back on...


I had exactly the same problem .Mine was corrected with replacing the O2 sensors .The sensors cost less than $30 each but cost about 20 mins labor per sensor .So if you got an honest mechanic the total cost will be around $130 .

codes are for fuel system lean bank 1 and 2. low fuel pressure or innacurate mass air flow sensor could cause this. most common is mass air flow sensor.
