In this video we have a look at a 2003 Jeep Liberty that had a customer complaint of "no throttle response." We also noted that the throttle light and check engine light was on with multiple codes. The key player was the code indicating a low reference signal. No scope or meter needed on this one. Just a good game plan and a quick look around found the problem pretty quick. -Enjoy!

Great job and video like always
Surprised this was not brought to you from another shop by the customer who had been told there he needed needed new modules to the tune of $1500. Good call. I would have never found it because that's not my job.
Isn't it interesting how many issues are caused by someone changing something and not putting things back to gather the way they were!!!
Administer the BEANS!!!!
I fixed this one with my eyes 👀 -Eric O
I’m gonna have to borrow that line…
Don’t recall if you mentioned it,but what And who they put in the vehicle can be the difference in finding the problem. It may look like plenty of clearance but when grandma puts four of Italian pastry eating buddies in to go visiting other old people and the axle bumper is pinching the fuel pump/sender harness as its pounding the frame rail. It may look alright on the outside of the conduit,but knowing what they do with it,you’ll probably take a little looksee inside and discover the carnage.
Finally someone who gets into diagnostics! Please keep them coming
Short video but boy do we learn a lot from them, cheers from the UK
Eric.. I suffer from P.A.R.T.S.D (Post Automotive Repair Traumatic Stress Disorder) The feeling of anxiety over if I did the repair correctly. Watching your videos has helped me understand if I have done the repair correctly, or what I am up against for the next one, I've done my own work for almost 40 years and rarely take a vehicle anywhere and just do it myself. Working with the newer vehicles are harder to repair and diagnose but I use sites like yours to help me 'F.S.O' (figure shi* out) I'll see if I can find some coin to send your way. Thx.
Great video Eric O @South main Auto
You are a JEEP WHISPER
Friend of mine had one of those fancy Audi cars with a V6 turbo of some kind. Had a tune-up done at the dealer. Then it started running like shite — making popping noises & stuff. Dealer says "It's water in the fuel! Put this panther pee additive in there and keep on driving it!" — so he did. He's going down the freeway and the motor exploded. Literally. Parts flying out into the street exploded. Turns out the dumbass mechanic didn't tighten the sparkplugs and one of them broke the tip off of it from the vibrations and a piece of it entered the turbo which disintegrated and went into the motor. KABLOOEY!!
Friggin' mechanics trying to figure out the problem never opened the hood. Never. Opened. The hood.
Insurance paid for a junkyard motor. 10K. Wow. So yeah — don't just plug in the diagnostic stuff. Open the hood.
This is not just visual inspection man, this is called experience+knowledge. Other mechanics wil have eventually solved that after taking the engine/tranny out, just because they moved the wiring a couple of cm in the process LOL.
My automotive teacher recommended this channel today!
What's with FCA and Chrysler/Jeep junk and all the inexcusable electrical problems? If it's not a bad TIPM, bad ground, bad connector, it's wires being rubbed through that were never properly protected to begin with. And why did it need a new driveshaft? That's like saying I need a new anvil. Jeep can't even make driveshafts that don't fail? I still can't believe you voluntarily bought a Jeep product. They're like buying an entire vehicle made of Dorman parts.
The one dislike must be from schrodinger. Lol
Why can't people do things the right way the FIRST time? Don't do this on an airplane. You won't be walking…..
Cars have way too many electronics in them these days. Way too many things to go wrong.
Eyes and brain best tools we got 😀
Your big advantage is the years of experience plus remember all the common and not so common failure areas and that makes diag life much easier with previous experience back you up .
I can do it, but not near as good, or knowledgeable as SMA can do it.
your giving Keith a run for the money on quick diagnostics !
LoL
How the heck are you supposed to make any money on that job finding that problem so fast? Lol
I saw something like that on a GMC Yukon before. But it was rubbing on the front driveshaft.
I found green crusty wires today on a chevy ☺
My truck a 1994 chevy c1500 beater was missing ,stalling and choking out.I pulled in a place for lunch jiggled some wires and found a loose connection on the temp sensor.When messed with the wiring to harness to sensor the truck ran fine .Yes an auto zone parking lot fix was in full affect.Iwas that guy.
Thank you Birthday Eric, giving us presents on your day. Appreciate you sharing.
easy for an experienced person like you phhhhttttt..going to the brake job…more my speed lol
i was waiting for you to say it had a dorman egr valve and it was taking down the 5volt reference LOL
Excellent
Eric,
Good call on that. I guess'Trail Rated' means the wires arent rated to not rub thru when driven on streets and highways where these things spend 99 percent of their time.
SMA#1
God bless
Paul
Full beans can be administered!
Nothing beats experience!
Are you on Stanton Island?
This SOOOOO reminds me of what and older mechanic once said to me. "Where was man last?" Meaning, what was the last thing done to the vehicle that MAY have caused the present issue.
Yes sir have seen that on more than one of them and great video showing what you can find with just your eye balls. Keep up the great work
Hmmm.. wonder what shop installed the drive shaft???
Chrysler vehicles in the past always seem to have that problem by the driveshaft I remember scannerdanner had an old Dodge Ram where the VSS wire rubbed through
also hearing detection lol it gets ruff when you have bad eyesight and bad hearing lol need those noise recorder things you have my diy is turn my phone into a recorder and put it in the area that you need to listen also use the camera to see for me lol works well when i have to depend on something i cant hear or see lol only lost one phone on the road lol
Good find
Don’t ya love it when the problem finds you quickly. Doesn’t happen all the time but like you’ve said there’s so many things connected to that CAN
5 volt reference wire. Pays to have a visual look before digging in. Saved you a lot of hassle. Nice work Eric 👍
You've showed us the power of visual inspection many times. This is yet another excellent example. Thanks Dr. O!
Wow, impressive. Your brain is really in tune with the stuff you work on.
Actually I think this diagnostic was pretty cool. The lowly visual inspection nailed it.
Exactly what I do, inspect it and then load the parts cannon! Bare metal in the rust belt is a bad sign!
Would ya just look at that! Just look at it! Lol
Ive fixed many things from just a visual, Neighbour brought his truck over that had a squeak, been like that for 8 months, fallow the “shit stain” from the rust to find his one lower control arm was loose and sliding in and out.
Thanks for the video.
I was wondering how many boring brake jobs it would take, now that Josh is back in school, before you called Keith and begged him for some interesting stuff to do up on Stanton Island. I knew you couldn't take it much longer. The nuns at my Catholic grade school use to tell us youngsters that an idle mind is the devil's workshop. They were often wrong but not in this case.
Can't beat a good old nosy at the part. In my experience alot of electrical faults are of this nature i.e. wiring damaged, disconnected sensor etc.
I remember someone showed me a car where the speedo wasn't working after a clutch change. Guess what was left unplugged.
That has to be at a used car lot.
👍 THANKS 🚹 👍
