IS nthere Prob with Air Intake Temp & O2 Values?

[dan]

Hi guys Its me again 🙂
I’m using a Honda Civic vtec 1.6L (ES5) i had few problems with this car, so let me quickly explain what happened.
>had a Problem with random over heating (after driving 50-60km car started to over heat)
>found out secondary o2 sensor was faulty , but ran with that faulty sensor for about 6-7 months knowing that there will be a impact on my gas cost)(other than Check Engine light there was no problem)

> then car used to stall in the morning when I’m starting for the first time of the day
(during that time I had to charge spark plugs regularly )

Then found out its the head gasket and changed it.
Wow everything is ok. no over heating issues.

but sometimes car rpm drops (when @ idle ) ( 800 to 650 ) and i feel a bit of a vibration

also car got stall when taking a Full turn (then said my power steering belt was too tight and he adjusted it)

so I plugged a bluetooth obd2 and used the car for few hours and recorded all the data.

I have attached a pic of some screen shots.
I have 2 Questions

1) Is my Air Intake temp is too high? (see the picture)

2) something wrong with my 02 sensors ? (I replaced the Secondary O2 sensor recently and i got it from ebay not a original Honda sensor

o2 Primary voltage is not stable at all (changes ~0.8V to ~0.01V)
Is that normal ?(see the picture)

I believe it’s a common problem to switch the intake air temp sensor connector with the IAC connector on those vehicles. This is something that might have happened during the head gasket replacement. All connectors are color coated to their components. Make sure the white and green connectors near the throttle body are connected to their corresponding colored components. If not, switch them and recheck for your problem.

Keep us posted.

ECT= Engine Coolant Temperature.

IAT= Intake Air Temperature.
