How to replace Oxygen lambda sensor Astra H P0141 (bank1 sensor2) 

5min job!!! haha, you must be kidding me.. good luck if you could get it out that easy..

you probably got your answer but, they're the same sensor, only difference is the lenght of the cable, downstream sensor will fit the front but the front upstream has too short cable.

Hi Tarek, yeah you have to use code reader after new sensor installed to erase an error and then should be alright :)

Simas J , i did already with OP- com but still have the same problem. The sensor read 4100 mv and status was inactive!. Any way i fit an OEM sensor today and it works fine.

Tarek Elbarbari check if there are any broken wires

its OBD 2 you can get it from ebay for less than £10. And Software call torque(lite) you can get it from google pay store for your phone or tablet :)

Are you the type of guy that good for looks over functionality . Wauw ...

Hi, you can buy from ebay, amazon, the parkers, or eurocarparts :)

Simas J are the ones from eBay/amazon reliable at all? They're very cheap.

they are cheap because they are unbranded, at eurocarparts u can get for £54.

Simas J is this the correct one? (for bank 1 sensor 2) error code p0141. www.eurocarparts.com/ecp/c/Vauxhall_Astra_1.4_2007/p/car-parts/exhausts/car-body-parts-and-car-exhaust/lambda-sensor/?710720101&1&0b628718ebcc3fcdd509dcde660a72f87b452830&000210

check by your reg plates, or you can call them to ask if it will fit. Its the best to order online and pick at store as you can save some money. What about this one? www.eurocarparts.com/ecp/c/Vauxhall_Astra_1.4_2007/p/car-parts/exhausts/car-body-parts-and-car-exhaust/lambda-sensor/?710721311&1&97ed0f7a93091536e992f8721bcabea95581ad39&000210

Hey David, you could try to unplug the battery and leave for few good hours it should reset itself then

Hi Csaba, Please check this link it might help you :) secure.lambdapower.co.uk/technotes/fitting_guide.asp Since I my wrench not showing torque, I just tighten it up until it's tight, of course not over tightening. If that makes sense. Cheers.

@@simash9213 Thank you very much Simas!

@@csabagardian3173 Your Welcome :)

Hi, just googled - P0130 is the OBD-II generic code describing an issue with the bank 1, oxygen sensor 1 (HO2S B1 S1). Hope that helps :)

So which one is it?🤣

@@Gelorks bank 1, oxygen sensor 1

Giudipeppe83 errrmm not sure what you saying lol - its 1,6l

if you cleared the error but u didnt change the sensor no probs, I did that couple times. The engine light will come out more often. After some time it will come up again. It might be the wires problem not the sensor itself.

Is this a really bad problem with the car ? Can i go to work Monday ? to work i drive 50 km, please tell me

In my opinion thats not a problem. I drove probably a full tank until i decided to change it. Your car may use more fuel, because the sensor doesnt work properly.

you can try, it depends how to tight sensor is, but I would not recommend.

Dants A - if you mean o2 sesnors, so one is underneath and other one is in front of the engine 😊

Simas J now i know for sure the right o2 sensor to replace,tnx!

Hi there, it has two sensors one before catalyst converter and one after.

Simas J شكرا لك

yes, it's after catalytic converter

Mines fault code is P0141-000,fault code description is O2 sensor 2 heater circuit,car is opel astra g 2002 year model,im confused cause it doesnt indicate bank 1 or bank 2 on the scanner,dont know which sensor is damaged or needs to be replaced.

@@dantsa671 - P0141 is for bank 1 sensor 2, P0135 code is for bank 1 sensor 1. Hope that helps :)

Simas J so it is located underneath the engine or car?

@@dantsa671 its underneath the car and the engine :D
