My post Cat sensor was seized, so much so I had to pop the rubber mounts and remove 3 x 13mm bolts at the catalytic converter to drop the exhaust, cut the sensor down to the hex portion to allow use of a regular socket and 24 inch breaker bar as the o2 sensor socket flexed and rounded it off. Then used an M18 re thread tool to fix the threads in the exhaust. The tool was £10, new gasket was £1.20, sealant was £3. Much cheaper than a new exhaust. Hope this helps anyone else out there
Hi there, my fuel on my Corsa D 2011 has recently been dropping faster then usual and is quite noticeable. I think I need to change the oxygen sensor but not sure which one.
Hey, thank you for the video. Are you 100% confident that the same 499 sensor can be used as the first sensor as well? I have 2 options. Use a denso universal sensor but i need to crimp the ends to a jack from the second sensor.. if that makes sense. Or use the second bosch 499 sensor and replace the first sensor before the cat.
If you have Corsa D with Z12XEP engine I'm 100% sure because I did it. For other engines, the effective sensor is not a problem, the problem might be the length of the cable. It is ok to measure the cable first to see if it fits. It's not a problem if the length is not exactly the same, it is important to easily reach the plug.
Hi, is it necessary to disconnect the battery too and why? If it's too avoid some temporary fault code I can erase it via the OBD diagnostic later. Thanks
Hi I recently got my exhaust changed due to a hole in the back box and middle section on my 1.2 2012 corsa d. Since then I have got the codes P0036, P0138, P0140 and P0141 (heater control circuit bank 1 sensor 2). I cleared the codes and drove for a couple of miles but came back on. Will I need to just change the lambda sensor myself and if so which 1 or take it to a garage?
Most of the time, this error is caused by a faulty sensor. The fuel consumption is a result of this. A proper diagnose will prompt this correctly. Sometimes this code could have other causes.
My OBDII scanner comes up with emissions failure for the catalytic and o2 sensor heater. I'm new to this and not really sure of what readings mean what. It also says it's running lean. Would that be because of a faulty o2 sensor? I do get the occasional misfire on a cold start.
The O2 sensor need to be replaced. The misfire is not related with te sensor problem. First check the spark plugs. Especially the one on which cylinder you have misfires, if it looks different from the others. Also check the coil, if the contacts are clean, without oxidation.
They have different codes, but physically the sensors are the same. The only difference is that the front one has a slightly long cable and it is more expensive.
It is recommended to use Bosch 0258006924 before and Bosch 0258006499 after the catalytic converter. The difference between them is the cable length and the price. For Corsa D with Z12XEP engine I used Bosch 0258006499 for both sensors replacement, the cable is long enough to fit before the catalytic convertor, so you can save some money.
Hard to say, could be coil or spark plugs, could be map sensor, lambda sensor. Hard to say without seeing the car. Engine sometimes stalls or lacks power after starting?
@@CorsaDForever No stalls or lacks of the engine. Could be the lambda sensor. Maybe i have to check the check engine light. My engine starts without a problem, could it still be the spark plugs? Thanks for your help
Hi, I have codes P0141, P0138, P0136 and P0140. I can't seem to find any Lambada sensors from a reputable brand. If only after Cat sensor needs changing can i still change the one at the top of the cat. Also would ot be possible to get links to both sensors. Anything to give the catalytic converter a clean maybe some sort of Liquid? Thanks
Look for Bosch sensors. If you can't find, is ok to use Denso equivalent. The best way to clean the catalytic converter is to go 3000-4000 rpm on a long road. If not working this way, means that is gone, need a new one. If after cat lambda values are in the same pattern as the lambda before cat, means that is gone. Normal engine with a normal cat shows lambda 1 similar to a sine wave and lambda 2 more like a straight line.
P1138 is related to the second O2 sensor and may indicate a faulty sensor. P1036 has nothing to do with the O2 sensor. You probably had a P0136. If so, it's almost certain that the sensor after the catalytic converter is bad. A thorough diagnosis, with monitoring of the parameters in real time would be indicated to be 100% sure.
The engine should run quite bad if that sensor it's gone. Without a proper diagnose I'm not 100% sure, but in most of the cases you have to replace it.
@@CorsaDForever thanks for you replay and do you no where is located the sensor 02 bank 1 sensor 1? it is the first sensor which you change in the video?
sorry if i ask you again but can i ask from where do you buy the key to open the first sensor ,can do you tell me the size of this tools?and also the sensor from where you buy?
Hi, I have the same motor and I have P0130 and P1035 and P0030, I want to change it but I want to be sure that is the real problem, can you help me mate?
P1138-00 O2 Sensor Circuit Malfunction (Bank 1 Sensor 2) Is this the sensor on the back of the exhaust. Where exactly. Is this and o2 sensor lambda sensor
@@CorsaDForever este din 2009, nu mi-a aparut nici o eroare si am pus si tester. Nu prea are nici putere, si cateodata simt miros de benzina pe evacuare.
Cel mai probabil sonda lambda 1, cea de pe catalizator. Mai poate fi si senzoul MAP de vina, e in spatele admisiei, spre partea șoferului. Pentru o diagnoza precisa, chiar daca nu ai erori, trebuie urmărite valorile pe tester in mers, in timp real. Daca mașina are peste 100.000 km e bine oricum sa schimbi sondele lambda, ca obosesc in timp si iți creste consumul.
