SAVE FUEL NOW! Use Hondash to analyze oxygen sensor performance and avoid high fuel consumption

Following video demonstrates how you can use Hondash as a tool to analyze your oxygen (lambda) sensor performance and determine if it's working correctly.
Please notice, the sensor can be faulty even if your check engine light is not on!
Faulty oxygen sensor is the primary cause of abnormally high fuel consumption and bad emission levels.

  1. This is very helpful. I hope to see more of this tips and analysis using other sensors like AICV, MAP ,etc.. Well done.

  3. This genuinely helped me out.
    apparently i had a faulty sensor, not getting any lights just once a a coincidental while i had these bog downs feeling like my engine flooded with gasoline.
    All fixed now, not a consumption withdraw that i had but no more strange bogs!

  5. I have a honda civic Ek3 2000 model and i am getting the negative short trim fuel for months. -21,-22, - while on idiling. There is no check light on the homdash scanner. But it gives the info O2 oxygen sensor DTC unconfirmed code value out of range. Help required!!!!

    1. If your oxygen sensor works exactly as described in the video, I would not worry about the negative trims.

  6. I have a civic coupe 1994 and the long trim always shows a constant value (something like 9.4~10.2). When I give a little bit more pedal, it shows an oxygen sensor error and the long trim starts to blink in red. Should it be a real oxygen error? Or could it be a normal behavior of the hondash? The other parameters work like the video, there is nothing different.

    1. It's very likely that the oxygen sensor is bad, the long trim value should never be in red alarm values, should always be close to 0.

  7. On the lamda readings i get voltage 0, the Air fuel ratio is at 17.64 all the time, and i get the message fuel trim oxygen sensor out of range. My mechanic measured my o2 sensor and says it works. Are the readings accurate?

    1. The value may be located on another address, but that sounds very rare to be the case. What car model, market, engine code, build year is it? You may try to discover the readings following this guide if the o2 sensor readings are indeed somewhere else: https://www.hondash.net/2022/05/protocol-configuration.html
