Yea i found this but was not sure which clamp would be the right one for doing Wideband sensors. I already have one like the 20/60a one on there. I thought there was a specific one just for micro amps?

I had considered making a fly lead with a length of wire on the signal wires loooped 10x over to amplify signal to use the clamp i already have but time is always against me.

Tom, do you know of anyone using this low current probe to look at a Nox sensor signal? I have been contemplating on buying one to use it for this and other low currents. Think this would also work great to verify current to multiplex modules. Years ago I had a Allen Bradley input card go bad by intermittently shorting to ground. It made my meter show the supply voltage drop from 13.6 volts to under the 8.0 volt threshold for the module to recognize the signal. I figured it out by isolating and testing the wire first, but it would have been cool to see the current spike upward on it.

No. The probe is very accurate, but does not have a very fast response time. Great for things that don't need that fast a response though. Wideband and AF sensors, MAF current, magneto resistive WSS, etc...

Hi Olly,
Welcome to the sqiggely line club, nice to see someone local.
I can not speak highly enough of the people here, always ready to help.
Autonerdz is the only place to consider buying a pico.

You could then create your own known good database under differing conditions from a near new machine.
Make sure you save any harness & plugs off old sensors.

Right seems due to my ignorance/ incompetence that not all sensors are wide band as i originally thought. Being such a noob i think i couldn't get a signal out of the ones i was testing before as my scope has a slow buffer rate when set to 1.0sec time scale and takes a while to display the waveform (very laggy). Being impatient i didnt give it chance to display hence no recognizable waveform. Soooo

I will go back and check the ones i had thought were Wideband and see if i can get readings, If so it means that the new pico may get bumped to the top of the wish list over the scan tool! Grin

I had the same thoughts too Olly, but after thinking about it myself, the Pico from Tom was the way to go. We pretty much have all the factory scan tools where I work so I decided the pico first.

I want to get a Scan tool next but since I discovered the nox sensor video from adpt training, I have started to druel over that micro probe and what I could do with it. I'm hoping to use it to see nox output from the engine and compare it to what is coming out of the scr side nox sensor so I can gauge the health of the dpf system. One more month till I have funds, so If I get one I will show everyone how it looks.

Just gotta get saving a bit but hopefully within the next 6 months.

Hi Nikk yea good to find local people with a similar mindset. Where abouts in CHCH are you based?

Was down your way in Easter for a south Island holiday. Sorry not a motorcycle tech but you might find car stuff very similar these days and the scoping technique will always be the same

Hi Autosparky,

Ye aim hoping to learn lots from browsing the threads and seeing what goes on in the car world as many of the systems share similar traits or at least test methods and waveform analysis techniques.

I pop up your way every now and again to visit my family in the capital, quite nice up there, nearly moved up after the quakes but descided to stay put due to Mrs's family being dowm here.
