Title: OBD 11 Screen problem
Post by Nunnspoet on Feb 16^th, 2019, 10:47am

Hi,
I have the Alex Pepper lead and have used it many times, happily.
I connected it up this morning: No codes so I went entered PID Possible, selected Long shift and short shift fuel trims and the MAF. I then went to Graph and entered in these. Nothing happening so I played about with the side data switches to no avail. I gave up the ghost, returned to 'Status' only to find the readings in the right hand window reading: Oxygen Sensor NO. Oxygen Sensor Heater NO. EGR NO.

I have disconnected and re connected a few times but nothing different :-/

I am stumped.

Help please, I love my Scorpio and miss driving her very much.

Mike

Mike,

I wasn't sure what you were saying so just tried mine.

Are you saying you highlighted PID possible & clicked send (or pressed enter). There's no advantage in that - just leave it as default (PIDSUP 01-20). If you want items not listed go to Enhanced along the top & select "Support" & press enter (don't select "All" or "Possible" - you just get things the car doesn't support).

When you selected say MAF & pressed enter was it displaying the data & time in the Data tab.

I assume when you went to graph you ticked the "plot 1" (or 2 or 3) alongside MAF etc.

"Oxygen Sensor NO. Oxygen Sensor Heater NO. EGR NO." usually means you haven't completed a drive cycle since the codes were cleared or since you disconnected the battery. Possibly you clicked a button that reset the PCM whilst trying to get the software to work.

I take it this isn't a fresh install of the software that hasn't had the unlock code entered.

Thanks Dave.

Since I last cleared the codes I have had the Bty disconnected many times as I have changed various sensors, so that could well be the answer to 'NO's'. I did indeed press the reset button, a couple of times, so that may have done something :-/ .
( Are you saying you highlighted PID possible & clicked send).... Yes Dave, I did that ::) But now I will follow your advice.

My Pepper Lead and the Laptop came fully loaded courtesy of my friend Graham Toye, quite a few years ago. I confess that I am really nervy about 'doing things' so I have not played about with it that much. But now it is a case of needs must ::)

More info on my other, related, thread.
