O2 Sensor Modification to Pass Emissions Smog Test for Code PO420 , PO430

This is a video on modifying the O2 Sensor ( Lambda bypass hack ) to pass Emissions test for code PO420 or PO430 on a 2005 Nissan Frontier 4.0L
Capacitor
4.7uF +\- 20% 35VDC
Resistor
470-ohm 1/2 watts 5%
Update : Update part 2 on the O2 Sensor modification • Update part 2 on the O...
Service engine soon came back on around 54 miles traveled I cleared the code .
Ok after 60 miles traveled the monitor went off and that time you can get your emissions to pass. But later check engine light came back on with a PO430 code that was strange but no monitors everything was complete . I cleared the code again and drove it for another 40 mile and PO420 came back but still no monitors.

When soldering, Tin your tip with solder. And don’t buy cheap solder…once you’ve tinned the tip of your soldering pen, clean it with a wet sponge. Re-tin and have at her! Solder will follow heat and as you found out, it is HOT!!!! Great video!

Hi, again thanks for putting the value of the resistors and capacitors up great help great content keep em

[@seamusrice1865]

Comin lol

Thanks for the update I just seen in the dcription save me a bunch of time !!

This video is for a nissan, other makes may be different. A nissan expects the downstream o2 sensor signal to be bewtween 0.1 and 0.68 volts. If your voltage is to low use a smaller resistor, to high and use a bigger resistor. The voltage swing should still be pretty fast, only slightly slower than the upstream o2 sensor. You need to use a very small capacitor like 1uf but this may vary. Also you can try with the resistor after the capacitor or before. If I remember correctly my cap is after the resistor (o2-resistor-cap-car wiring). Good luck!

What you recommend for the Honda civic d15z4 engine

[@lechero1811]

FYI, the computer must monitor the exhaust through a complete drive cycle, Google it, and then it will make a determination if the CEL stays off. If you fooled the ECU, then ur good. But some newer car ECUs will vary from Stochiometric to lean or rich and expect to see a change in the downstream O2 readings, but if you have the cap/resistor mod, the “sensor” output will not change accordingly and you are back to square one, aka P0420. 😮

Peugeot 107,(citroen c1 and toyota aygo) recepie is: 4.7uf capasitor and 50kohm resistor. Works like a charm💪

[@esa7269]

@@Neal-j4y i would go with capasitor and resistor shown in video🧐 it is pretty usual and shown to work in many cases.

[@jdmtake1]

Great videos will this work with 08 Dodge Charger for the rear o2 sensors and set the monitors 😊

[@bubbaclaypoole7579]

I have straight pipes and I need to delete the sensor so how will I do it ?dodge ram 1500

[@deanlhouston]

Your video is incomplete. It takes time for the engine computer to run the catalyst diagnostic test, so the trouble code won't appear immediately if this doesn't actually work. Did your trouble code re-appear or not after driving it around for ~80 miles or so?

[@gallantfox4776]

06 toyota tundra doesn’t work tryed with 1 ohm or versus 1 mega ohm with 4,7 mf 50 v capacitors it gives po606 ecu code Any idea why

[@marshallmarshall7918]

It looks like the positive of the capacitor was connected to the black wire. And that the negative lead of the capacitor was put to the signal wire. Assuming that the Black wire is a Ground, connecting the positive lead of a capacitor to a ground won't do any damage?

[@jbolding39]

Black is the signal wire

[@audimanuk]

@@jbolding39 Sometimes the signal wire will be the grey wire, and black wire ground ??

[@ACPTVIDEO]

Did this end up working? May want to give it a try myself. Is resister and capacitor same for all car makes/models?

[@gregmooney4090]

that pretty slick

[@seamusrice1865]

Hi, great 👍fix ,which resistors and capacitors did you use???

[@OJacks]

I will add in description

[@omaromar13]

thank you very much

[@vw66bus16]

I used a 33pF electrolytic capacitor + 150kohm resistor and my output is basically flat line at 0.5V it fluctuates +/-0.05v. I don't yet know if the C.E.L. will remain off.

[@superj462900]

Did your CEL remain off with these component values?

[@audimanuk]

Did the fix work ????

[@EZchairchillen]

We must know if this works!!

[@vw66bus16]

No, I was unsuccessful at keeping the CEL off. I am thinking that there is an electrical issue with the vehicle (2010 Chevy Traverse). I have since removed the RC filter from the sensor circuits after replacing the cats. And still no success

What the value of the resistor and capacitors

[@raymondferguson1935]

Could you draw it on a board it a very hard to see what you're doing you could also go it in more detail on a board thanks

[@bindiberry6280]

Consider the black wire is ground. After cutting it up, kzbin.info/www/bejne/rpapi4Nqoa-VpNU and then connecting a resistor from ground to ground (black to black) is nonsense.

[@artificialintelligence734]

Black wire is usually the signal wire.

[@artificialintelligence734]

Black can be a heater wire also but not a ground, at least on a Toyota anyway.

[@jbolding39]

Black on this one is signal
