it has to do with the ecu loses signal during cranking.

my question is this:

i am in Saudi Arabia right now and after my deployment I will be tearing into my runner for some TLC, does anyone know how to fix this or know the code number? I have looked and found OBD1 code lists but none show this problem.

I am buying the parts now and need to know what else to buy. ie. harness, knock sensor, PCV valve...

To stop the backlash i took the runner to a dealership to have the code read and to see if they could rebuild the 3.0. the guy laughed and said ill sell you a 4.3 GM for 1000 instead. they did a print out but i forgot the code number, and it is not here in my tent, so please help.

thanks

Here is the code number you are looking for:

3.4SWAPASAP

Fink

Fink

why would i go with a motor that has min. gains? i would try for the new 2.7 liter but not the 3.4.

good try and hey man, thanks for the help.

bump.

I think someone has put a Jihad on your logic.

2.7 over a 3.4? Riiiiiiiiiiight.

3.4 swaps are really sweet Murphy! You are going to need one if you plan on keeping up with the cream puff! I happen to know somebody who might be willing to sell you one with an ECU & harness!?!? No trans though. Sorry I don't know the codes you are looking for. Have fun in the sand box bro, thanks for your service.

How is a 3.4L a minimal gain over the 3.0L as compared to any of the 2.7's ?? And the only thing the 3.4L toyota has a slight disadvantage in is the torque values

yotarob2005

I just took a spin around the block in my bosses 3.4L 1st gen Taco after he installed a TRD supercharger last night, Damn that thing was quick! I wouldn't steer you wrong buddy. 3.4L FTW!

murphyz

my opinion. I want a 3.4 but they are expensive and here is my logic. please review.

cost cost plain and simple.
hp/(cost of engine)=ratio of hp/$
3.4-1400 rebuilt +ecu,harness is extra=.135hp/dollar spent
2.7 about a 1000+ecu and harness.=.187hp to $ spent
4.3 with a auto tranny ecu and harness 700-1000.
=.271hp to $ spent
cost is the only factor. 3.4 is a good engine, but the 2.4l they put in the rav4 and the Tc can be super charged also


$1100=.146
161 hp (120 kW) @ 6,000 rpm
163 ft·lbf (120 N·m)@ 4,000 rpm
200 hp@wheels / 185 ft·lbf with with supercharger.
again not the best but cheaper by far then the 3.4+supercharger combo...

i have been in one and my uncle owns another with the super. it is great but i base my value on hp/$

Lysmachia

Cost is the reason Troy and I had to scrap the idea of a 3.4 in Tippy. Now we have a running 22re (in Tippy II) for now but will swap the 4 cylinder 3vz (God do I have that right??) Apparently the wiring is much easier but I am only going on hearsay and some research we have done. If I had the $$ Hell yeah I'd do the 3.4!!!

murphyz

we all would. or one of the v8s. but most including myself dont have the cash to "blow" on the best motor. sometimes we have to make do with what the wife lets us... haha

toyota4x4907

The 2.7L you're talking about is for a front wheel drive vehicle. There is no tranny that you could use to make it into your vehicle AFAIK.
Also, the 3.4L is a pretty direct swap, whereas the 2.7L would take fabbing so put more $$$ in there.

xxxtreme22r

yup, good luck spending the money on that particular 2.7L motor and getting it to work in RWD/4WD.

murphyz

my mistake. i put the wrong engine. If i cant find a 3.4 with ecu and harness...for the price of a 4.3 or a rebuild of the 3.0, i will just rebuild. again cost is the factor of reasoning.

i know they make rav4 in 4wheel drive and it uses an older version of that motor. Iassumed it was the same as the scion Tc's engine. i was wrong. i thought that the rav4 and the tc used the same engine, they did for a few years. here is the specs on the 2ar-fe. not the 1ar-fe[/COLOR]

again my apologizies.

• Toyota RAV4 (ASA33/38), 181 PS (133 kW; 179 hp)@6000, 233 N·m (172 ft·lbf)@4000
• Toyota Camry ASV40 (Base & LE), 171 PS (126 kW; 169 hp)@6000, 226 N·m (167 ft·lbf)@4100
• Toyota Camry ASV40 (SE), 181 PS (133 kW; 179 hp)@6000, 232 N·m (171 ft·lbf)@4100
• Scion tC (ANT20), 180 hp (130 kW), 173 lb·ft (235 N·m)

i believe those are for the new 2ar-fe engine that took over for the 1ar-fe engine.


not saying i would. i am still saying the 3.4 is not a viable choice unless i can get one for the price of a 3.0 rebuild/4.3 swap.

dntsdad

As someone that has swapped the 3.0 for the 3.4, I dont care what those numbers state, The driving difference is incredible.

To say that the swap is a "minimal upgrade" is like saying an upgrade from a .22 to a .45 is minimal as well.

To properly rebuild your motor you'll be in what $1200-$1500 by the time you do all the little things. Not a chance I would stick half that into another 3.0

Just my opinion

murphyz

or...like a 40 to a 45...in my case

i agree the 3.0 has issues but in my experience i have not had one blow up til i bought this one(already bad). I do hear alot about it so i know the failure rate. im saying my old runner did fine with the 3.0 and it had 186K on the stock gasket. ran like a champ.

my grandfather and uncle have had a t-100 and taco respectfully. they love the 3.4, it is underpowered but better by leaps and bounds in reliability. but numbers are numbers.

my brother had his 94 runner rebuilt mostly himself except for the machining, and was in it 790.00. he didnt buy all the sensors and extra this and that. just what he needed to get her on the road.

he drives 200 miles home from college each weekend to meet his "love of his life". that was 80k miles ago he did his. still running great. he wheels his runner more then i do, in southern oregon.

i have priced the parts for the top end,gaskets, and hoses at about 800-1000 but that is with 300 for machining. why would i pay 1200-1500 for a motor with 190k on it and then have to pay another 1000 bucks to have it gone through... those 3.4s are most of the time not drop in ready...

back to the original question (since you all want to bash on the 3.0) does anyone have the answer to my ecu code question?

xxxtreme22r

the 2ar-fe engine was also a FWD/AWD engine. will have same problems as the 1ar-fe. And as far as cost pre HP, I would not be looking at the HP in the these trucks, I would look at the torque. I would sacrifice the 10HP for the 220 ft.lb of the 3.4 over the supercharged 2ar-fe's 185ft.lb in a heartbeat.
