Need help to find MAF Sensor on 2005 Toyota Hiace 2KD FTV auto diesel

I have a 2005 Toyota HiAce 2KD-FTV auto diesel. I have been getting lost of power, I change the air filter, work well for a few hours and then the problem return, I was told my MAF sensor may need cleaning as I took too long to replace filter. I have been searching for the location on my vehicle for MaF sensor. Please don't say it by the airfilter, because I have search and can't find,

    i take when you say it is remaining on the cold start. are you referring to the EGR valve.
    also note, that i really do appreciated the time you have taken to assist. Thank very much

    No friend, the computer works the cold start when you turn the switch. The temp sensor sends the cold message to the computer puts it in cold start mode and takes it off when engine warmed. If it's flooding and making black smoke, the temp sensor is saying it's cold and it's like always having the choke on. Temp sensor malfunction causes that situation. it's staying in cold start mode. And it's cool Bro, I'm just relaying some of my own experiences from my past.We're good pal.

    BTW, EGR is Exhaust Gases Recirculation Valve. That's emissions control stuff and when it's bad, just causes a poor pick up deal when throttling up on hills and taking off, loss of power. That's all it does. Nothing on the engine startup.

    I just started working on the van removing the component for the service of the MAF Sensor, there no MAF there at the intake from the airline from the filter, that goes to the throttle body and EGR, I am DIY guy, if there is picture that will be a great help. I will take the throttle body off and service, just one more bolt at the bottom that I am having problems removing, then I will have access to the egr and temp sensor to also service.

  • Rigger DeBusk Oct 22, 2019

    You either have a throttle body or a Mass Air Flow. One or the other, never both. If it's a throttle body, that would be in the position of the old style carburetor. A MAF is on the front end of a snout type of manifold that the breather line is connected to. Whichever one you have, the throttle cable will be connected to a lever on it.

    We found a Intake Air Temperature Temp Sensor For Toyota 89424-12010 170400-6020, it was in front located above the air cleaner, behind the front bumper, its all hard plastic, Took it out and spray with MAF cleaner, there was not anything to clean, don't forget my vehicle is diesel, test drive, idle better and smoother, not to long after the it start struggles and bucks as before on slight inclines an going over fly overs. not sure this type of sensor can be service or has do be replace

    Now your saying something pal. Everything you've just said points directly at the EGR. Replace the EGR valve and you should these problems no longer. I don't care for EGR on a diesel, but it's all a part of emissions control. I took all that stuff off my 6.2 Chevy diesel, a hand built 74 4x4 on a '83 chassis, and it runs so much better and no more smoke at all. Just a bit of white smoke, raw diesel fuel, on startup from the cold start system I built on it.

No friend, it isn't by the air filter. It's the unit that is connected to the intake and the air filter flex hose goes to it. This MAF is mass air flow, and there is a wire across the venture of the unit on the inside. First, purchase a can of Mass Air Flow Sensor Cleaner from an auto parts store, CRC makes this spray cleaner made special for this sensor. The sensor IS the wire that runs across the venture of the MAF. Take the MAF unit off the manifold and air line from the filter, it just bolts on, keep your fingers and anything else away from the sensor, and spray it real good with the MAF Sensor cleaner. Spray the venture also to clean the bore of the unit. Put it back together and if, in fact this MAF sensor was the problem, the cleaner spray will have taken care of the situation.

Testimonial: "Thank you, I think I spot it at the bottom of the EGR sensor that is attached to the intake. I guess I will have to remove the EGR sensor unit to get at the MAF sensor and service the EGR Valve I hope this works, and hoping this will stop the black smoke"

    The black smoke is just the excess fuel because it's constantly stuck in cold start mode. Get the spray cleaner for the MAF sensor. It'll clear up if that's the problem. But then staying in cold start mode by the computer because of a faulty temperature sensor. Check that while your there.

  • snar_tt Oct 20, 2019

    Which one of the temperature sensors are you referring to.

  • Rigger DeBusk Oct 21, 2019

    Bro, I didn't know there was more than one. I'm lost on that one, I just know a temp sensor is faulty when it's doing the black smoke like the choke is on. You'll have to test each one to see which is the culprit. Pull the connector from each and put a wire between the 2 on each and see which one goes to the gage. The other would go to the computer. They should look the same.

I have a 2005 Toyota hiace 2kd turbo diesel when I'm driving its loosing power as if the engine is going to shut down, I did 2 different scan/diagnostic and the issue still haven't resolve.

Save the diagnostic checks until there is noting else to physically check, look at or adjust. Best practice is hands on - first!

Try checking the turbo boost pressure.
Check for restricted exhaust, especially if fitted with a particulate filter.
Check the operation of the egr valve.
Check all vacuum connections and pipes...

My toyota hiace with 2kd engine is producing a cloudy black smoke and hard stating what could be the problem

Black smoke means too much fuel .
Have you changed your air filter or is it clean. A dirty air filter will flood your engine.
Is your choke working properly?
Could be your carburetor float is sticking.
Not sure but there are computer sensors in some makes that could cause flooding if they are not working properly.
I am sure there are other things that could be the cause but you can start here.

The pump is probably ok from the tank but the injector pump may have been damaged if the filter failed and allowed particulate to enter the pump also the injectors themselves maybe clogged best way to check the pump is with an oscilloscope (lab scope) check the amperage waveform with the lab scope and calculate the rpm , also check the fuel pressure from the pump with an appropriate fuel gauge
