  1. 2004 is before OBDII was mandated in Australia, so there's a good chance it's still either a proprietary Toyota system (ie Techstream) or J-OBD but using the OBDII style plug.  I know for my 2006 Corolla the scanner connects via ISO 9141-2, but it also auto-detects it so I don't have to choose anything (it just cycles through them one by one until it gets a response ping)

    Hilarious. Karmic in some ways too 😜

    Back in the 80's I also recall a famous sticker that used to get around with an Ethnic flavour.

    "You toucha my car, I breaka you face" 🤣🤣🤣

    Anyone remember that one ??

    And the classic "Insured by kung-fu/the Mafia - you hit me, I hit you"

  3. Toyota are correct, your engine (7AFE) has a MAP (Manifold Absolute Pressure, aka vacuum) sensor, not a MAF (Mass Air Flow) or AFM (Air Flow Meter) sensor.  The MAP sensor will be a small black box most likely bolted to the firewall, and connected to the intake plenum via a vacuum hose.  It is also most likely not the problem.

     

    Engines need 3 basic things to run - fuel, air, and ignition (known as the fire triangle).  If the delivery (or the timing) of any of these is impacted, then the engine won't run properly (or at all).

     

    Air is the easiest to check, and is also the one least likely to cause problems - basically, unless the air filter is completely blocked, or the throttle is stuck closed and the idle passages gummed up (or conversely a significant vacuum leak after the throttle), then the engine will run fine.

     

    Next is ignition.  Check the condition of your spark plugs, plug leads, distributor cap and rotor, and replace anything which is worn/cracked/broken.  If you can get the engine running, then bridge the TE1 and E1 pins on the engine diagnostics connector (under the black plastic cap attached to the passenger side strut tower) and use a timing light to check that the base timing is correct (should be about 10 degrees BTDC).  If not, then loosen the distributor and rotate it to set the correct base timing.  The condition of the spark plugs can also help diagnose if the problem lies in the third point of the triangle, fuel.

     

    Lastly is fuel (the hardest one to check, and to fix).  If the engine fires but doesn't want to run, then it is almost certainly a fuel problem.  The fact that you can get it running briefly by spraying tonnes of MAF sensor cleaner (essentially pure hydrocarbons) in the intake, much like Start Ya *****, makes me think that the engine isn't getting enough fuel.  Pull out the back seat and see if you can hear the fuel pump priming when you first turn the ignition key to ON.  Whilst you're there, remove the fuel pump (this might need the tank dropped on the AE9x, can't remember) and see if the filter sock on the end is clogged.  Test the fuel pressure at the fuel rail.  Get the injectors cleaned.  Replace the fuel filter (in the engine bay).

     

    Your biggest problem is that it is intermittent, and thus you can't tell straight away if the component you replaced/cleaned etc has actually fixed the problem until the problem goes away permanently.

    Remove maf sensor and spray with electrical contact cleaner (do not use non flammable one in eats certain plastics) you can buy maf sensor cleaner although this does exactly the same job half the price and still reside free….failing that if you require new sensor I use auto parts online or rolan 👍

    SXV10 5SFE doesn't have a MAF sensor, just MAP.

    Hi All

     

    Just in process of purchasing a 1997 Celica ST204 SX Auto 2.2 and getting a bit confused when looking for parts. I need to but a radiator and front rotors but when going online to look, the compatible vehicles always comes up with "GT" after the ST204 and I have no idea if they are the same or, if the ST204 is classed as GT here in OZ, any help advice appreciated

    The catalogues are probably pulling from the US market, where the 5SFE-powered ST204 was badged as GT (the lower-spec ST which we didn't get was the 7AFE-powered AT200).  Should be pretty similar to our SX/ZR models (which are both 5SFE ST204s) but do be aware that things like brakes etc can vary from market to market even for nominally the same "spec"

    The brakes are engaged mechanically via hydraulic fluid pressure, so the instance of it just braking on its own is rather peculiar. 

    Whilst the brake application is still mechanical/hydraulic, the actuation can be via the ABS pump (either as part of the ABS of for stability/traction control) which is electrically controlled, hence the possibility of an unintended brake application without touching the pedal (and with fully functioning calipers).

  7. Amazing what a difference even just body-coloured door handles can make. Also replaced the front-left (passenger side) window belt moulding which was starting to peel quite bad.

    Body-coloured rub strips are sitting here waiting to go on as soon as I can get a heat gun/hair-dryer and some goo-gone for the old weatherstripping adhesive.

    And once again the wagon steals the good bits intended for the 102...swapped over the 101/111 Superstrut twin-piston brake conversion, figured I might as well make use of the pads and stop the seals drying out whilst the 102 stays off the road.

  8. Rego papers don't usually go in to detail about model/trim etc (plus sometimes they can be a bit wrong).  As long as the VIN/engine number, number-plate and relevant details for road tax/insurance purposes (mass, number of doors, type of vehicle etc) are correct, that's all that really matters.

     

    And technically a Vienta is still a Camry anyway, it was just the badge put on the top-spec V6 models (the XV10s were badged as Camry Vientas too) - just like how a Calais is still a Commodore but it doesn't wear the badge.

  9. 203 ft-lbs is ~275Nm, which is pretty normal for strut-to-knuckle bolts on Toyotas.  When you say "stripped", do you mean the actual thread on the bolt/nut or did the head of the nut get rounded off?

     

    Also, what was the condition of the thread before you tried to tighten it up?  Suspension bolts cope some of the worst conditions of any fastener in the car.

     However it would seem the Australian built cars had heavier duty steering parts and so each time I try to obtain the parts they are wrong.

    May not be a case of "heavier duty", but Australian-built cars needed to have a minimum percentage of Australian-sourced parts in order to qualify for government subsidies.  Hence, a lot of the mid-90s Toyotas would use steering/brakes/transmission parts etc from TRW or the like (which had a presence here to support Holden/Ford/Mitsubishi/Toyota) rather than Aisin/Denso Japan.  Unfortunately it also meant that unique-to-Australia part numbers and VINs often don't show up in worldwide catalogues.

     

    If the thread issue is anything like my AE102 Corolla, the TRW rack has M16x1.5mm threads on the tie rods (both ends) whereas the (probably) Aisin Japan one has M14x1.5mm.  At worst, you can use these thread sizes and the length dimensions you know are right to sort through locally available catalogues and hopefully find something that matches.

    This week the news from the UK is that two-tone colour scheme has been discontinued in the UK (from Dec 2022+) and customers are getting single-colour scheme.  The reason given is that 2-tone colour scheme requires significant additional work at the Yaris factory which the factory cannot afford due to a very high waiting list.  This makes 2-note colour scheme un-economical for Toyota to produce.

    Is the same likely to happen to Yaris hatchback model in Australia?

     

    The Euro-market Yaris is manufactured in France and the Czech Republic, waiting list issues there will unlikely affect Aus-market deliveries from Japan.

  12. With jobs as important and complicated as clutch changes, I say that if you don't know what to do or how difficult it is, it's out of your skill range and should be better left to professionals (unless you're 100% willing to learn and can afford to have the car off the road for a significant amount of time if you encounter problems or don't have correct tools etc).

     

    As for the RPM, 3000+rpm @ 100km/h is perfectly normal for a 7AFE/C52 combination

    There is no excuse really for someone to think that passing hot engine oil through a rubber hose would be a good idea right ?

    There has to be a rubber hose somewhere in the line to accommodate engine movement (same goes for clutch lines etc, and even exhaust pipes in transverse engines need to have a flex joint of some sort to prevent the flanges from cracking), plenty of oil coolers over the years have used flexible rubber.  The key thing is whether or not THAT section had to be rubber (and whether the chosen rubber was sufficient or not)
