I am getting a p0141 code, where is this sensor located

Always clear the code and see if it comes back first. Especially with an O2 sensor code.

The P0141 code refers to your o2 sensor heater circuit. while many times replacement of the o2 sensor can solve this problem you possibly have a short or open in your o2 sensor heater circuit. Also was the proper o2 sensor changed p0141 is the bank 1 number 2 sensor. Bank 1 refers to the side of your engine where the #1 cylinder is located sensor 2 should be the second sensor on that side depending on how many sensors you vehicle has. hope this helps

P0141 indicates oxygen sensor 2 in bank 1. Bank 1 is on the side of the engine where the first cylinder is.

Your firing order (and the location of your cylinders) can be found here:

And further reading on the code you pulled can be found here:

The fault code P0135 means O2 Sensor Heater Circuit (Bank 1 Sensor 1)
The code P0141 means O2 Sensor Heater Circuit (Bank 1 Sensor 2)

Hi there:


P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141. See also: P0135 (Bank 1, Sensor 1).



A code P0141 may mean that one or more of the following has happened:



open or short to ground in the wiring harness
O2 heater circuit wiring high resistance
O2 heater element resistance is high
Internal short or open in the heater element
Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

02 sensor heater circuit, bank1, sensor 2.

P0141 Heated o2 sensor. P0134 Heater 02 sensor circuit, These 02 sensor has a fuse in the engine junction box listed as IGN 1. This supplies 12volts to the heater circuit, check to make sure its not a open fuse. If you already replaced the sensors make sure you clear the code. or it will stay in memory.

P0141 is O2 Heater Circuit (Bank 1, Sensor 2) It will be the sensor AFTER the cat on the side that has #1 cylinder. On your car it's the PASSENGER side.

p0136 and p0141 are o2 sensors and p0401 is a egr flow and the p0171 means its running lean on low bank 1

Hi....
The code P0141... Is : Heated Oxigen sensor Bank 1 sensor 2
Is the sensor Located before of the catalystic.
Normalli this code come when the sensor is damaged. in short.
or Disconnected ON rare CASES ECM defective.
But I recomend clear the lights. and drive the car untill the light come back. if is the same code. Check the connections of the code if the connection is ok. REPLACE the sensor.

I hope this help on your problem....
Any ,more info. I wil help as soon as possible.
