I would say new sensor with gauge, But I'm sure someone on the interwebs has figured out how to tap into existing sensors with an aftermarket gauge and get accurate readings.

So I reworded the knock senso, and light still comes on.

I'm gonna have to tear it down again...

It only comes on with light driving, when getting on it doesn't come on. Makes me think that it's not the circuit, why would the circuit only be bad under light driving?

About the water temps: I would think that with a beefier, high HP they put a cooler thermostat in. This would lower the engine's temperature since the thermostat opens faster. Not an issue really, since it's still plenty hot in there.

No idea...
I'd start the vehicle, then while you grab the wires under the hood, and any connecting wire, wiggle them. You'll probably need someone to watch the CEL on the dash to see if it comes on. Trace that wire as far back as possible and look for any issues on the jacket or connections.

And, are you sure its a code 52? I have misread code numbers before, ended up chasing my tail.

sorry I don't have any words of wisdom, I'd be upset if I had a new engine like yours and something simple is fouling my good time!

Definitely a code 52. Read it like 4 different times, but I did get pics of the exhaust setup.
They did an awesome jib used the same y-pipe and o2 bung because I didn't want to pay more for them to make custom ones. Had them rout it around the transfer case.

Sorry to hear that bro. I suppose the negative press about these engines is true, they have their issues. But when you get it all figured out I'm sure that engine will be awesome!

The code 52 doesn't really have anything to do with the engines quality. Its just a bad circuit.

Gamefreakgc

True, but it does affect performance considerably since it will severely retard your timing. Hope you can get it figured out.

I'll get it figured out. Just need some funding. Going to buy a new Toyota sensor and pigtail.

Tomorrow will be 18 years since I drove my 3.0 3VZ-E Pickup home from the dealer's lot. The overall thing I've found with the 3VZ-E is this: they don't tolerate neglect mainly because of the funky exhaust crossover and fragile cooling systems. And its induction and exhaust systems are packed in there making issues difficult to repair which doubles the aggrevation.

That's why there are people who've pulled their hair out working on these and those who've driven hundreds of thousands of clicks without any issues.

Updates?

Have you chased down your code yet? Ive been considering a 3.4 swap but would be really interested to see how this is treating you

teaMJPx

MAN! I have code 52 also... KNOCK SENSOR... I have ordered the pigtail and hope my 3VZ-E runs fine after replacing that...

Let us know if a new sensor fixed your issues. They are freaking expensive...

I also bought a new sensor and pig tail harness for sensor about 250 bucks total !! But tell you what my raptor 190 hp engine is running smooth ! Only got 2500k miles on it thou , but so far so good , gonna try and pass smog this Thursday with it

Hey just about to do a 3.4 swap but ive been reading about this raptor motor and just wondering how the power compares to to stock 3.0 and 3.4? Kinda in a bind cause I'm curious to how this motor works?

black toy

mine ran on 4 cylenders 4 a year went places v8s couldent sounded like a tractor. every budy just needs to take their time and do what thir engin is telling them to do like any engine fule watter spark you go its not rocket since good luck all

Fixed code 52. Tore it down and put toyota sensor And pigtail and it's fixed! So much better. Running premium93 octane and 20 degrees advance. And its running awesome! So much more power it accelerates through all gears no problem! This engine is great!

And I love my exhaust setup.

RBX

Did you mention what exhaust setup you are running?

Glad to hear you got 52 fixed.

I hav the thorley headers, with a custom routed down pipe and y. The down pipe on passenger side goes between the transfer case support and the body right next to the tcase. Then turns right and goes into a universal aftermarket cat and a magnaflow muffler.
Alvin muffler in Alvin Texas did an excellent job if anyone reading this is any were near the area.

Now I remember. I read so many 3.0 threads...
