Best part: Finding the bent pin at the PCM. Did NOT see that coming, lol.

Second best part: Paul using a cordless ratchet. Seriously, I've been thinking he's needed one of those forever! Perfect for all the random fasteners you end up taking off during diagnostics.

I got a Snappy one about a year ago, changed my life.

Thanks Tyler! I definitely need one of those.
How'd you like the spider scene :unsure:

Oh yeah, loved that part too! Cracked up laughing once I realized the other guys were pranking you.

One of the techs keeps a fake spider around? You know that's gotta be a fun shop to work in :cheer:

Pretty good you were able to straighten that pin on the ecu. That can be touch surgery.

Don't sweat the spider gag, I hate those things! They're everywhere in the junk yard come fall...
Just out of curiosity, what was the reasoning for going after the tps code and not the O2 first? Was there a driveability issues pointing in that direction, or just an ease of access thing?

I think mainly because the O2 code was for the downstream sensor. So that made the TPS code a priority. Second, the customer stated that the truck would not start with that "chip" removed. So again, not worried about the downstream o2 there either.
Make sense Noah?

By the way awesome video Paul! Not the first time I saw a problem with Power boxes/modules... And when I removed them couldn't even feel the difference when driving.
Gotta love that spider joke! :lol: :lol: :lol:

Longer ago than I care to mention I worked for an airport authority here in Scotland, a real spider much larger than that was living in the instument store in the Airport Duty Engineers porta cabin. Huge spiders are not a thing you see often in damp cold Scotland this one had obvious hitched a lift on a cargo plane.

There were 10 engineers & tecs shared that cabin and they all obviously regarded it has somedody elses problem as was there for a couple of weeks.

I'm telling you, I would have loaded my britches from boots to belt!

As soon as you fire up the acetylene torch under a car that's been sitting in someone's yard for any period of time, they all start descending down by the hundreds! Took me MANY years to get used to them crawling on my face without losing my cool and just dropping the torch...

Really enjoyed that one, as usual.
This video and the fact the owner got away with not damaging anything inside the ECU made me think of the discussions about the test-light bypass test on 02 sensor circuits. I understand they're not invincible as shown in the recent VW video but its also worth noting that 12V supply into the TPS sensor circuit didn't seem to damage anything.

Hello watched the vid to day ,nice work again paul
The bent pin in the ecu/PCM bending it back is not easy and on camra ???
I would also agree it looked like the ecu was doing a relearn when you started up the car after the remapping box. Thing was removed
(New web site looks cool well done guys)
Keep up the good work???
