OBD II code P0133 (O2 bank 1 sensor 1) which

Hi Amanda , I want to help you with your question, but I need more information from you. Can you please add details in the comment box?
USA car or NOT? USA is WJ jeep gas engines.
sensor B2S1 is bad. or worse.
or wires to it burned up , clamps bad and wires hit red hot
exhaust pipe
no engine told 4.0L i6 or 4.7L v8
must be v8. bank 2.

the front sensor is bad (aka upstream)
bank 2 is not cylinder 1 bank.
on USA car , bank2, seated in driver side
is right bank of engine is 2.
facing said engine is left bank.2.
the sensor is here

in the USA there are 2 v8 smog parts, CALF or FED

seen here clearly in the service manual oem I have in hand



the 4.0 liter is very trick this year,
it has an odd splite exh manifold
but only seen on calif engines,
see next photo for 4.0L engine,

Here's a link for codes P0446,P0443. https://www.obd-codes.com/p0446 Here's the link for P0403. P0403 Exhaust gas recirculation EGR circuit malfunction Here's code P0135 P0135 OBD II Trouble Code O2 Sensor Heater Circuit Malfunction Bank 1... Here's code P0141 P0141 OBD II Trouble Code O2 Sensor Heater Circuit Malfunction Bank 1... Here's code P0155. P0155 OBD II Trouble Code 02 Sensor Heater Circuit Malfunction Bank 2... Here's the last code.yay P0161. P0161 OBD II Trouble Code HO2S Heater Circuit Malfunction Bank 2 Sensor 2... The last 3 codes might just be one sensor.

• P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
• P0171 System Too Lean (Bank 1)

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..

i have replaced an O2 sensor and had similar failure after 1500 miles.
I removed it, chkd it, reinstalled it and it ran fine.
P0133 is related to slow response of O2 sensor. P1134 is mfg specific so google that for ur car.

Is the car a V-6? If so, look at the engine from the front, pulley side, bank 1 is on the left, sensor 1 is before the catalytic convertor.
If you are having problems with one O2 sensor, it is a good idea to replace them all if money allows.

P1131 is "Lack of H02S-1,1 Switch, Sensor indicates lean" I'd say you've got a bad Heated Oxygen Sensor at Bank 1, Sensor 1.

If the O2 Sensors are original,you could just change the front 2

The ones closest to the engine.

Any other issue you need to actually diagnose, as codes
are for just that reason

They don't ever tell you to replace anything

Running rough is more the O2 Sensors

Plugs
MAF Dirty
Vacuum Leaks
Ignition Coils going bad

P0340 OBD-II Trouble Code - Camshaft Position Sensor Circuit Malfunction

This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms can include:
* Hard starting or no start
* Rough running / misfiring
* Loss of engine power

Causes: A code P0340 could mean one or more of the following has happened:
* a wire or connector in the circuit could be grounded/shorted/broken
* the camshaft position sensor may have failed
* the PCM may have failed
* there exists an open circuit
* the crankshaft position sensor may have failed

Possible Solutions: With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
* Visually inspect all the wiring and connectors in the circuit
* Check for continuity in the circuit wiring
* Check the operation (voltage) of the camshaft position sensor
* Replace the camshaft position sensor as required
* Check the crankshaft position circuit as well
* Replace circuit wiring and/or connectors as required
* Diagnose/replace the PCM as required



P0133 OBD-II Trouble Code - Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)

This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Symptoms: You will likely not notice any drivability problems, although there may be symptoms.

Causes: A code P0133 may mean that one or more of the following has happened:
* The oxygen sensor is faulty
* The wiring to the sensor is broken / frayed
* There is an exhaust leak

Possible Solutions: 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


Hope this helps (remember to rate this answer).

p0135 indicates bank 1 sensor 1 which is before the cat.

check the mass air flow sensor there maybe dirt on the filiment inside the sensor causing false readings. cleaning or replacing it may make the codes go away.
