Hi Guys

I am new to this forum, so hi.

Anyways I have this problem with my Paseo (92) where it cannot keep a constant idle. I have done some checks and it seems like the MAF (little black senor stuck on the firewall that is connected to the inlet plenum with a vacum line) sensor is stuffed. Now i have tried the local Toyota dealer but he is a tool and doesnt want to help out with the part as the car is an import (i know all of them are) and he cant find it on his system.

So what i am asking first is, has anyone had a simliar problem and second can anyone help me out with this part. (This is what is written on the part: Sensor Assy Vaccum -89420-16020, -100798-2282, 5V, Denso).

Cheers

Fil

Mate, whereabouts are you? I can undoubtedly track you down one through my work. I'm in Slacks Creek, QLD.

Thanks the_random_hero, if you could track one down that would be awesome

I am in Perth. I am not sure how this would works, is it possible for you to send it here or do i pick it up for a toyota dealer here?

Oh and what would the cost be? ;)

I'll see if I can get the Toyota part number for you, so you can just ring them up and ask for one.

Just so you don't confuse parts interpreters, it's a MAP sensor, not a MAF. Very different things (MAP = Manifold Absolute Pressure, MAF = Mass Air Flow)

I dont know.

I did a quick search and they say 5E-FE. I could be wrong.

Yes, it's a 5E-FE. Starlets run 4E-FE's, Starlet GT's run 4E-FTE and Sera's run 5E-FHE's.

ok cool... just with my experiences with 4AGE's... they experience a Hunting Idle problem when there is an Airlock in the Wax Temp Sensor in the Auxillary Air Valve.....

This is on the Throttle Body right at the butterfly valve... with an absense of water there.. the aux air closes.. and idles up.. this causes the wax to heat and it opens. and hence it opens and closes and on and on. I suggest try and bleed the air from the top of the throttle body at the wax temp sensor.

On another note, i was looking through the car last night and i noticed that when i turned on the headlights the idle started hunting more (i hope this makes sense).

Is there something that would cause this to happen (ie the alternator or battery)?

yeah its part of the idle up mechanism... when you put extra load on the engine... such as turning on the headlights (the alternator needs to work harder... ) the idle up solenoid kiks in.. that could e just enough to flip the Auxillery Air sesnor on the throttle body and open up causeing the idle to hunt.

NOTE... when you're bleeding the cooling system.. make sure your heater is allthea way to HOT to ensure you fill the heatercore with water too!

So the alternator could also be an issue?

No Not at all... i mean i cant be certain without actually seeing it... but everyones car "idles up" when the alternator takes on more load... its normal... all i am saying is that as your car idles up... the Auxillery air sensor takes on more load, and opens.. and that could be enough to trigger the hunting idle problem thats caused by the airlock in the wax pellet sensor in the throttle body

The guy at work that knows Toyota's inside and out has finally been in when I've had a chance to speak to him, but some bad news. Our computers got reformatted a few weeks ago and we've lost our Toyota catalogue.

Are you definitely sure it's the MAP sensor? Try removing it from the intake and just place it in the engine bay and see if your engine still has the same problem.

Nah dude I am not sure if it is the MAP sensor but when ever I unplug it the car seems to idle better. I have also noticed that the idles gets worse when i turn the headlights on.

So maybe the guy at work will have a better idea to what the problem could be.

Hey gucio,

did you get to the bottom of your idling issues.

I recently got a 91 Paseo as a 2nd car and evertime i get off the highway it seems do have the same issue as yours . The idle Hunts and it can be bit embarassing especially if the driver next to you is looking your way..

Have you both checked for vacuum leaks? I've done some asking around and this has been the most common thought to your problems.

      Disconnecting winch, lightbar and UHF

      Generally, yes. In the 60s, and earlier, there were cars with positive grounds, so I'm always a bit hesitant to say the negative wire. It is always the one that bolts to the body. Herb

      2011 Land Cruiser 1VD-FTV Engine Won't Start After Overhaul

      Hi everyone, I have a 2011 Land Cruiser VDJ200 with a 1VD-FTV engine. I recently had the engine fully overhauled due to a blown head gasket. However, after the overhaul, the engine is not starting. It only cranks but doesn't fire. I've checked the following DTC codes: Internal memory EEPROM error Low rail pressure The actual rail pressure data shows: 240 bar during cranking 61 bar when ignition is off Based on these findings, I suspect the following potential causes: =Defective Diesel High-Pressure Pump =Leaking Piezoelectric Injectors =Diesel Fuel Bypassing to the DPF Circuit =Faulty Injector Drivers I'm hoping for some expert advice to help diagnose and resolve this problem I'm seeking expert advice on how to troubleshoot and resolve this issue. Any suggestions or guidance would be greatly appreciated.

      Disconnecting winch, lightbar and UHF

      Disconnecting batteries, ALWAYS disconnect the ground wire first. Doing this will also disconnect power, in general. Herb

      Disconnecting winch, lightbar and UHF

      Hey guys, I’m wanting to disconnect my current winch, lightbar and UHF as I have new plans. I’ve installed a winch previously on another car so I get it’s a case of following the cables and disconnecting from the battery, etc but but safety wise, should I start by disconnecting the battery so the cables aren’t live orrrr? And if so how do it go this haha?

      Snapping wheel and axle studs

      Put a set of standard wheels on it and your problem will disappear. It is critical that the hole in the wheel centre is a snug fit on the axle boss (without wheel nuts fitted). If your wheels are sloppy on the axle boss this allows excess force on your wheel studs and they will break, as yours are doing. If you are unsure of what to do, go to a reputable tyre shop and get assistance.

      2zz idle / roughness when accelerating past 3k

      Hey everyone was hoping someone might be able to point me in the right direction with this issue I've been facing for a while now. My Celica's idle will drop down to almost 200rpm when stationery after hitting operating temperature. Pretty much feels like it's about to stall out but never actually does. When taking off from a set of lights it almost feels like it hesitates or is down on power and then all of a sudden it lurches forward and gets a boost in power again. Then again around 1,500-3,000rpm it feels down on power and in what I can only describe in the engine feeling scratchy. Past 3,000 rpm it gets a little boost in power again but still definitely feels down on power compared to what it used to be and still has that roughness. Note lift is also not working at the moment but I have changed the lift bolts, planning on cleaning the VVT and VVTL-i OCV's New engine mounts have been installed I changed the MAF sensor about 4 years ago albeit not OEM. After doing some research my main ideas now would be a New MAF this time OEM, TPS, IACV or Coil Packs (Changed plugs 50,000km ago) Any other suggestions would be greatly appreciated!!! :)
