Thank you for this video. I had check engine light, read error P040B (Exhaust sensor "A"). Bought and installed new sensor. Reset error with cheap OBDII bluetooth scanner but after few rides check engine come back. Then I found your video and in my case voltage on connector was 4,87V. New wire to ground point solved problem. :) You could do a video how properly clean clima evaporator with for example Wurth spray. Probably from passenger side there is special hole in center console, near legs, behing carpet. Good trick is use teflon spray for seat belts and window seals.
hi. I have the same code trouble in mercedes A class w169. But when i make the test you made in this video i found exactly 5.00 Volts. (first i found 0 v, but when i put engine i found 5v) what do you think about that please? thank you
First thank you for your reply. I check the other video (i check all videos 😂 it's all good) to test the sensor. If i understand really good i have to remove the sensor. Put a multimeter and use a heat gun. the more it heats up, so the more I heat up, the resistance should be to zero, that's right ? First i have to found how to remove it, i don't have the tool you use in the video
@@boyakst8573 follow exactly the video instructions. The more you heat it, the higher the resistance in ohm. You need an egt sensor socket or a crow foot.
Hi. Can you give me the reference of the piece for classe a w169 please ? I don't remove it at this time i need to buy the good tool that you have in the video What is the size of it ?
Hi nice job. 👍 Is it possible the temperature sensor can have an issue but no fault code showing besides error code p2002. As when trying to do a regen the temperature is not coming up on a Nissan Note E12 1.5 DCI.? Or is it just a badly blocked dpf. Had a few regens done and replaced glow plugs and oil and filter change and cleared all other codes.
Hi, not an easy question. I think sensors can be bad without trouble codes. Check if with cold engine it gives plausible values, and how it varies during driving. If you can remove the sensor it's even better, you could check how it works (see my other video). But it's highly probable you have an issue with back pressure sensor or clogged dpf. Sorry but I don't have a clear answer Good luck
@@ticktime6569 Many thanks for taking the time to reply. Makes sense. Yeah will be best to start with to take of the back pressure sensor and test it as well as the temperature sensor. The soot level is at 43% and not going down during a regen. Must be a root issue that needs looking in to or the dpf is clogged as you mentioned. Many thanks once again. Will give your other videos a look at quite interesting and clearly explained. :D
@@josefernandes9655 no it shouldn't be started. Some ecu send 3.3V if I remember well, probably the value is fine. Try to search on the internet about your car model

Wow great 💪thank you for sharing your success. Glad to help 🙂
Great video thank you!

Hi, I think that reading 5V is not enough to say the circuit is fine. Test the sensor first, it could be faulty (check my video)

@@boyakst8573 you mean the socket? It's simply an egt sensor socket set, measure is 17 mm if I remember well

@@ticktime6569 did you end up fixing the issue? My dpf is clogged getting p2002 and p242a regarding my egt sensor
@@shahienafzali1281 what is your car's model?
I measured my exaust gas sensors voltage and all give 3.32 V...is that normal?
Hi you mean the voltage at the connector with sensor detached?
@@ticktime6569 yes...I just put the key on without starting engine...should be started?
