Hilux SW4 3.0: Falhas P167A, P167B, P167C e P167D - Motor vira, mas não pega | Doutor-IE

What's up, then Gabriel says, it's a Hilux, it's a problem with the injector of the Hilux, I said it's the injector, whiplash here, what happened, what did you bring me, so Toyota powdered milk, some cars with this injector like this They don't have the need to do that offset code right, the advice I have applies to the Hilux and the SW4 3.0 with this technology and the RP which became known as the whiplash injector, this one has the technology and the rt and the Hilux more The new one also has it, not Gabriel, but it is also new and keeps it, that is, the injector has six cables, right?

That's because it has the injector, right? That's an electric weight injector, right? The newer one also has this 6-wire injector, but the configuration is slightly different, it has one connector, right, and the injector on the newer one is 6-wire, it also has the technology and the RT is both focused on the doctor. and, true, Gabriele says that it is Hilux 1kd ftv-2 K10 TV and the r t the Code that we specify America, that is, a ii-rt that we put in addition to the author and is related to this technology here of pressure and temperature monitoring of the injector that has a kind of Zinho module inside and this makes the central control over the injector very fine, right in the o and in these trucks, these injectors do not need that famous modification of the magnetic code of the injector in which it sort of adapts there to the variations in internal pressure due to wear of the injector, that is nothing more or less true Gabriel and that is exactly if you can put it on the slide I have a fault code that appeared there and that is how the story goes I'll just let you tell the story Now, tell the story, the customer is right.

We were contacted by this Railux and they generated a fault code which was p1167, correct, 67, loss of communication with the cylinder injector, correct. , if it was that, if it was the

p167b

ball, it will be cylinder 2 and so on, I don't know, wait, wait, wait, now you confused me, loss of communication with the injector that I entered. the electrical diagram, I didn't like it, well come on, loss of communication, injector, love open, old, it doesn't communicate with anyone, let's go with this ok, wait, let's check So let's go, so we had to get in here when diesel trucks came in and utilitarian, look how interesting, right Gabriel, I was looking at these six cables, guys, for those who don't know, I know that the people who work with say you're sick I want to know this, right Gabriel, but I'm going to give you a little refresher here, I can calm down, feel free, I'm going to laugh a little here, here's the thing, there are six IOS in the injector, guys, this little harness here is there, look, just look at terminals 1, 2 and 4 of the injector, the terminals that are connected to the pressure sensor, each individual injector is as it is.

It has an individual King pressure sensor on each injector. The sensor is specific for that injector, right? Gabriel gives it to him and refers to each injector in English pressure, he will show on the scanner the pressure and temperature value for here or for Victor. It will be the injector temperature, one, the ejector pressure, another, and so on. Oh, and the pressure, look at that, there's a pressure sensor. You can see the pressure sensor ground here when finished. 115 volts from pressure sensor to terminal 2 or I know. If I take a jump kit to measure, 5 volts are coming and the pressure sensor signal is terminal 4, then terminals 3 and 6 are the pulse control wires in the injector to make it open to control the beauty of the coil and the big one, Big surprise here, what's the biggest doubt Guys, right, Gabriel is terminal 5, which is a lin communication network.

In other words, the injector communicates with the control unit and through which certain information passes, including the temperature, what temperature it has. a temperature sensor inside, right Gabriel, that is a question we have, isn't it that there is no analogue temperature signal, you won't listen to me if you put your oscilloscope on them you will see that it is a square wave pulse, a beautiful signal, do you have any information. So you can say that this injector talks to the module, right, Gabriel, what you were talking about, right? And then you will have this Link Network signal to test it.

Be with an oscilloscope to be sure what is happening there. It is the network of songs two in this edition only one, but the graph will be a very similar digital signal in the other, the squares of a square wave. Well, a calm address and that's it. That, then on the slide there I have the rest of the story, right? The rest of what happened, well, right, it wouldn't start and in fact the engine would crank but it wouldn't start, why not? It started? We were trying to figure this out. I asked our subscriber to come with a scanner and see what was happening in the injection center, and only with the admission he already saw that one of the injectors in the case.

Injector one showed a pressure of 2,500 Baron right, very high pressure canister with the key on and you should be able to send it to zero, right Gabriel and only about 01 male volume because I smile, right? In the conversation I asked him, let's just disconnect this injector from cylinder 1 and see what happens, right, and when he disconnected it and then started it, the central injection began to control the other three injectors and the engine caught the employee with three. cylinders but it was already running, so with that incorrect depression information that came from the pressure sensor and internal injector of cylinder 1 it did not even start, the pulse would not come from the Bel injector, the pulse would not come from the control unit, it must be programmed for a value case is very different between the injectors it is for safety it doesn't even leave the engine legally running very cold so the moral of the story is that the repairman must be attentive. the individual pressure of each injector, right, this is important to have a scanner that can take these readings, I understand well, so what we recommended to our client was to change the injector that had the failure, that's right, it was when the engine was already It worked and everything went well, so okay, so the information.

The main tip is that this 6 wire harness injector has a pressure sensor, a temperature sensor and it has monitoring, so you can use the scanner to monitor these two, let's continue. Take a look to see if they are coherent, through them you can also find Palhas and the repairman in this case, right, Gabriele was not related to this and this is a defect that was not as complex but as it was. In a car the guy drove every day he got confused so guys I know we're going to hit this injector you don't need to program the code and when you change it you just put it in there and then it will talk.

Through the network link with the injection center and there they will understand that they leave control, he needs it too, it's nothing.
