ok 🙁 then what about my secondary o2 sensor , shouldn’t it be consistent(voltage ) ?

I tried with another app.its showing a lower air intake value now (earlier it was 150F/65C)
now with this new application its around 122F/50C (my ambient temp is around 90F/32C)

Hi Thanks.
my ambient temp is around 86-90F when car is cold(switched off overnight) Air intake temp matches that. but after driving about 20-30 mints its goes up to 130-150 mark,
so when the car engine is hot intake air should be hot(130-150F) bcos if it,s getting air from air intake (through air filter ) it should be hot anyway bcos engine heat. correct me if I’m wrong

Oh thanks Karl
then my both o2 sensors acting how it should.woow 😀
but 60-65 C air intake temp is too high??

Hi i just checked the Air intake Temp again. it was around 85-90 (car was switch off for more than 12 hrs frm its last start) I think its in Fahrenheit here normal ambient temp is 30C (86F)

so u think 150 F (65 C) is too high?
Thanks

What is ECT ?

saw your O2 sensor video , according to that quick lean – rich change is normal.
But but secondary o2 sensor doesn’t change that much,(one i bought from ebay)

is it a faulty sensor?

Thanks

“get a IAT reading it should almost equal the ECT reading perfectly.”
what is ECT ?pls explain

Also I haven’t done a proper ECU rest after that(head gasket replacement), other than removing the fuse and putting back.

Is there proper a way to reset the ECU ??

Thanks
