Hi

I have a 3223. The automotive knowledge base has the title -MAF testing using "Block Mode".

This is for Pico 5. Appreciate if anyone could tell me how to set up for Pico 6.

Thanks a lot ,Peter.

Hi

If a zirconia o2 sensor complete waveform is biased towards the rich [low in o2] in closed loop and the ecu leans out to maintain the A/F ratio, how come the o2 waveform appears to stay the same i.e. still showing a rich reading at a steady 1500rpm.

Appreciate any help offered.

Peter.

Dear Tom, thanks for the reply, I appreciate what you are saying about coil extension leads. In with a chance with 4 cylinder engines, but how would you test in situ the coil cartridge packs of a V6 cylinder engine. To fit coil on plug leads would be totally impossible. I’m a Mechanic by trade. Wher...

I have a 3223 - does anyone know: About the connectivity to the large coil pack [complete cartridge unit for say a 4 cylinder engine which sits between the camshafts] It is an all in one unit. I Just need confirmation that all I can test with this type of assembly is secondary ignition. However any ...

autonerdz,

Thanks for the reply. Does not really help me though as it keeps shutting off. I have got a pico 6. Ijust wanted a few answers to the above question if possible.

thanks peter

Hi I would appreciate some guidance from a helpful person as to how to put 2 waveforms on screen at the same time, explaining briefly voltages and timebases for the different waveforms that would be on screen. An example would be very helpful. I just need to know that I am doing it right. Also how w...

I understand a digital signal waveform i.e. on or off, for a sensor giving out a digital signal, but how do you explain the waveform of an actuator[digital signal] which is earth controlled. Is the timebase classed as the drop down to earth,i.e. actuator on, because the normal digital signal with a ...

Hello forum - I would be grateful if anyone of you can answer this.

If I am looking at the waveform across the view of an idle speed control valve - digital signal. Is this waveform just a repetition of one cycle continuously?
