Replace any upstream O2 Sensors with 100,000 miles
on them or codes as you have

Leave the downstream monitors

SOURCE: where is the bank 2 sensor 1 located.

Oxygen sensors are always numbered like this:

Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2

some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2

Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.

Sensor 1 is always the upstream sensor (The one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.

Most GM engines have #1 cylinder located on the left bank, (or Driver's Side) of the engine,

So, the answer to your question would be that you are looking for the sensor located before the catalytic converter on the right (or Passenger Side) of the truck.

Hi

Have you checked the EGR valve, and or the air flow sensor? both could cause it not to start!

Also ensure the earth battery lead has a good connection to the car body from the battery.

Please get back to me if your unsure about these parts.

Regards
Dan

Engine is probably sucking air causing the lean condition

Not the fuel filter

More like a vacuum leak

Hi Michael, After fixing errors you need to reset your computer by disconnecting the battery for a minute or two, Also you'll need your radio code to reset your radio, I hope this helped...........CHEERS..

Check engine light comes on i hooked up my code reader under the steering wheel and it threw this code PO133 any idea's of what it is or how to fix


The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
  • Check and fix any exhaust leaks
  • Check for wiring problems (shorted, frayed wires)
  • Check the frequency and amplitude of the oxygen sensor (advanced)
  • Check for a deteriorating / contaminated oxygen sensor, replace if necessary
  • Check for inlet air leaks
  • Check the MAF sensor for proper operation

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

1996 Oldsmobile LSS. Went to autozone and got code PO133. 'Fuel system running rich or lean- check other aacodes first.' and 'Oxygen sensor defective'; The guy said it probably isn't the oxygen sensor; as...


code P0133 is : o2 sensor circuit slow response (bank 1 sensor 1)
meaning;;;one heater on o2 sensor is not heating fast enough or no heat.
look for o2 sensor heater fuse first
and connector wiring for rust
if ok change o2 sensor

My 2010 dogde charger 3.5l v6 has code p0153 and po133 and u0126 with the check engine light on what could that be.


code p0153 refers to heated oxygen sensor-1 bank 2 slow response/no activity detected===causes ---heating inoperative---wiring---oxygen sensor.
code po133 refers to the same problem as 153 and states the oxygen sensor several times so I would be replacing that unit.

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

I Have 7 codes on my 2000 Ford Taraus PO743, PO750, PO755, PO760, PO442, PO133, P1131. Would you be able to tell me what those problems are?


P0743 Torque Converter Clutch Circuit Electrical
P0750 Shift Solenoid A
P0755 Shift Solenoid B
P0760 Shift Solenoid C
P0442 Evaporative Emission System Leak Detected (small leak)
P0133 O2 Sensor Circuit Slow Response - Bank 1 Sensor 1
P1131 Lack of Upstream Heated Oxygen Sensor Switch -Sensor Indicates Lean -Bank 1

The transmission has a problem with shifting, and the evaporative emission system has a small leak, the O2 sensor has a problem on Bank 1 Sensor 1 either in the sensor or wiring.

The sensor is about the same as 1 hour labor time at the dealer, the sensor will not in most cases be defective with this code, something else is causing this engine to run rich.
