- This video shows how to replace a bad O2 or Oxygen sensor based on the engine codes below on an M112 or M113 Mercedes car. The engine code for this car was P0141. So, I am replacing Bank1's (passenger side on left steering vehicles) post catalytic converter or downstream sensor (sensor 2). The same procedure applies to sensor 2 of Bank 2 on the driver side. Sensors 1 on either bank can be found in the engine bay obviating the need to lift the car.
I purchased the O2 sensor from rockauto.com for $62 including shipment and tax as of June, 2023 - part# Bosch 13782. The same part works for both banks but only for post cat sensors with shorter cables.
Engine codes for Bank1 Sensor 2:
P2031 Exhaust Gas Temperature Sensor Circuit (Bank 1 Sensor 2)
P2032 Exhaust Gas Temperature Sensor Circuit Low (Bank 1 Sensor 2)
P2033 Exhaust Gas Temperature Sensor Circuit High (Bank 1 Sensor 2)
P0136 O2 Sensor Circuit Malfunction (Bank 1 Sensor 2)
P0137 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)
P0138 O2 Sensor Circuit High Voltage (Bank 1 Sensor 2)
P0139 O2 Sensor Circuit Slow Response (Bank 1 Sensor 2)
P0140 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)
P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
Engine codes for Bank2 Sensor 2 are:
P0156 O2 Sensor Circuit Malfunction (Bank 2 Sensor 2)
P0157 O2 Sensor Circuit Low Voltage (Bank 2 Sensor 2)
P0158 O2 Sensor Circuit High Voltage (Bank 2 Sensor 2)
P0159 O2 Sensor Circuit Slow Response (Bank 2 Sensor 2)
P0160 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)
P0161 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
Thank you great video
Thx, Mitch.
Excellent video but a couple questions. The O2 plug, when connected, has to slide out of the metal bracket that holds it first, correct? Do you have to slide the plug to the side, or up, to get it out of the bracket?
@pfsantos007 thank you. You just slide it out. Please see starting at 02:10 minutes of the video.
p0154 is the upstream O2 sensor on the driver side correct? what part number is needed for mine? your videos help me a wholeee lot!!
Hi and thank you. I have the codes listed in the description of the video.
Hey I have a code showing bank 1 sensor 1, I believe it is upstream but not sure if its left or right, do you by chance know which bosch part I need for 2014 s550 base? Appreciate your help and videos! Hoping to do this myself as well.
Thanks. I explain where bank 1 and 2 sensors are at 3:20 minute of the video.
Hi can you please let me know is it ok to use Bosch oxygen sensor instead of original Mercedes brand
Hello, I list the exact Bosch part number in the beginning of the video...
Bosch is the OE manufacturer indeed. So, take Bosch 👍
@Masood I have a 2010 mercedes e350. I scanned it it says bank 2 sensor 1. Is it upstream or downstream? Passenger side or driver side? Thanks for any help
Hi Bilal. I explain this in detail in the description of this video. Yours is driver side pre cat.
@@masood-tvthank you very much for the quick response
You're welcome.
Wait, so all of the four sensors are close to the 2 front catalytic converters? None on the 2 in the middle of the car?
Correct, measuring what goes into and out of them.
@@masood-tv thansk man!
@@salemsuljkanovic2067 my pleasure.
Hey Masood
I have problem in my car w210, the trunk doesn't open, when i remove wire of battery it work about eight times and them doesn't again, i hope understand the problem, if you have any idea about this problem
Hello Abdallah, is that with the key fob, car button, or both?
@@masood-tv both
@abdallahdaw7045 it is an electric connection issue. Get a wiring diagram, and a volt meter with resistance function and check at all connection points
Is that cylinder 2 or 1
This is for either side, but the downstream sensor or sensor 2.
Mine says bank 2 sensor 1 is that the sensor In engine bay the very first one
Hi Jemal, yes, it is the one in the engine bay.
@@masood-tv ok thanks on my 2013 ml350 how would I remove it the computer is in the way
@jermalramsey1567 I can look it up for you in a day or so, since I have never replaced the sensor on that car. However, don't be afraid to remove the computer or anything in the way. Just remove the negative battery cable first.
