I Won’t Fix This Toyota 4Runner

rev up your engines, here we have a Toyota that smokes and why is it smoking that's what we're gonna figure out that's why the customer brought it over here and in this case to check engine light is on so is the vehicle speed control and the traction light they're all on so here we have to start with a scan tool plug it in on the port and we'll see what it says it knows it's 4runner and now it's thinking in this case it's got four codes the cat is inefficient the cat isn't efficient again the cat is inefficient again and see 1201 engine control system malfunction now smoking can be a blown head gasket but in this case it's not losing any coolant and the sections been going on with the customers car for quite some time now I did a block leak check before a couple months ago showed there was anything wrong with the head gasket leaking it's not losing coolant so really there's only two reasons that could smoke is either it's getting too much fuel flooding out the engine and it smokes or it's burning a lot of oil and this case is burning oil it's only a little bit on the very tip so it's an oil burning problem but I really don't think that's all because it's high mileage they often burn a little bit of oil but when this thing smokes smokes like that then it stops oil burning generally gonna happen all the time I think it has to do more with that computer communication code we're gonna look that up don't go on my all data repair see if there's any bulletins or recalls on this and hope I'm walking through all the TSB's technical service bulletins and recalls but there's nothing about a c1201 unfortunately in a search engine when I put it in says no results down C 1201 and what does it gives you a bunch of procedures in the end it says replace ECM if you can't find anything else wrong and as we look it up I don't feel like guessing with a 537 dollar part now to further confirm my diagnosis I got my old fancy scan tool but it recorded no misfires it didn't show any bad data it was running like up and smoking even though the engines burning a little bit of oil hey it's got 200,000 miles on it and burning oil isn't going to make an engine Rumble and tumble and trip that communication code either twelve years old it's only done this a few times anybody in their right mind would be foolish just throw a computer at it I gots all the cost to mark drive it and see what happened cuz if it gets to a point where it's doing it all the time it's gonna make the diagnosis a lot easier because I'm suspecting the computer and that thing's bad but if wiring door to it is bad our particular sensor is bad can do the same thing since it's doing it so infrequently it would be stupid to guess with the $600 part right off the bat because I had a customer with the same exact vehicle years ago it did the same thing I did it every once in a while and they drove it another four years without fixing anything as long as the coolants not being lost we know the head gasket is not blown as long as it runs decent almost all of the time and it works fine on highway sharp it doesn't run at all it runs bad all the time yeah but this thing runs perfectly fine ninety nine percent or more of the time but as I said my gases on the computer mainly because it had no misfire codes it should have at least recorded when it was stumbling and rumbling when it was doing the smoking and it didn't do that at all now only time is gonna tell where this solves 4runner and I'll be sure to keep you in the loop if it does end up having to get a new computer put in it but for the time being driving around see what happens because as long as it's not losing coolant and it's running good most of the time it would be foolhardy to throw a whole bunch of money into it right away because let's say it is the sensor going bad or wiring going bad well then that will stop working entirely then when I get my fancy computer and look at the data say it was the crank sensor or the wiring I'd see that that data was either non-existent at zero or is giving observed data out would you show me that there's a problem that you don't want to guess with an expensive computer only to find out there's a little short down the line somewhere and these hundreds of wires and ends up ruining your expensive new computer because that little thing eventually over time got worse way like it's worse if you want to fix it without spending money foolishly and they having to do it all over again because your brand-new computer it got fried in the same way if the original one was so that's repair we're gonna wait to see what time shows and if you want it about the traction control like being on an ABS like being on that's a software deal with Toyota if your check engine light comes on and there's a problem it automatically turns off the traction control system and the ABS system so those warning lights come on when I reset the computer says you can drive it away all those lights went off and stayed off but the problem comes back and the check engine light comes on those are come on so don't freak out if you ever see that in the Toyota with a check engine light that's just kind of an ancillary effect of the check engine light coming on usually there's nothing wrong with those systems at all, so if you never want to miss another one of my new car repair videos, remember to ring that Bell
