This is in line with my understanding, and why I was curious initially whether OBD2 data can be trusted while the ECU is doing its calibrations (or whatever).
I may have been overly terse in my response, this medium ain't perfect. I appreciate your input, and reminders to stay the diagnostic course are good things to hear especially when there is a risk of rushing the job and doing sloppy work. No offense intended nor taken.
I was parroting a term...
Thanks all, much appreciated.
Fair points. I freely admit to trying to short-cut this a bit, the weather is not going to hold out much longer here and I do not have a heated shop.
It suffered from a slightly high idle before the O2 code, and I happened to see the TPS value on the scan tool...
I must have missed the OBD2 part in there--I do see the meter/feeler gauge method however. At this point then it seems like it is worth a try to use the live data, it will either work or it won't.
@ZackR Thanks for the info. Makes complete sense.
Full disclosure for the question is I was hoping to take the shortcut and use live data to set the TPS as several here have recommended. If the scan tool is receiving the ECU's interpretation and not (I assume?) the raw signal, that method could...
Hi all--Chasing a P0125 on my 1996 LX 450. It was intermittent, then the other week it became permanent and the truck started to run very rich (by smell), rough, missing, etc. Checked upstream O2, found signal wire hanging by a corroded thread, replaced the harness side connector.
Started it...
Hi all--Please see my Craigslist ad for more detail and photos, but briefly, I sold a 1970 FJ40 project and no longer need these new reproduction panels.

Hi all--Due to unforeseen personal circumstances, my 1970 FJ40 basket case needs to move ASAP. See thread here: 1970 “it’s all there, I swear” project - https://forum.ih8mud.com/threads/1970-its-all-there-i-swear-project.1289702/
Disassembled, rusty but complete truck. Engine starts and runs...
PB Blaster Surface Shield. Similar to Fluid Film but Harbor Freight has it so I thought I would give it a shot. I have no experience with Fluid Film but this stuff seems to grease things up pretty well.
I believe so. I need to verify but I would guess whoever built this would not use the 80...
That's the idea, ha.
A few more details: the throttle cable itself is Toyota, the plain wire version. The only point the cable is supported at the bracket is where the end of the 90 cable guide tube passes through the last, smaller cantilever on the bracket, which is how the bike manufacturers...
