Toyota RAV 4. Computer management

TOYOTA RAV4 NO YEAR TOLD AT ALL. AND MATTERS HUGE.
1az-fse 2.0L GAS,inline4 MADE 2006 TO 2016 ( SORRY CANT GUESS IT)
Toyota's D-4 direct injection system.
not told can you drive car after your wise trick? yes/no?
if yes do you get full power:? from the engine>??yes/no?
if yes, then at STOP signs does engine stall but if you use a fast right foot you can maintain a good idle,? (hard work foot)??????

you said> (and is a wise act)
step on the gas pedal? IS A KEY TEST FOR ALL ENGINE,
BUT HOW FAR DID YOU PRESS "STEP IT" the pedal (depth)
100 % OR 5 % (ABOUT)
5% ADDS AIR AND HIDES A DEAD IAC SOLENOID.
100% is magical PCM secret UNFLOOD mode, test
it cuts fuel 100% you unfloods the engine of raw few and wet spark plugs.

most time causes are
IAC dead, clean it.
injectors leak.
FPR bad stuck closed and fuel pressure is 2 times spec.floods
bad spark plugs. over 100kmiles is NO GOOD

chain drive cam is good, if guides fail it screams loud fix me.
and more....

no VIN told
no year told 1968 to 2023, impossible to guess year.
no country told (wow)
this engine class? real names?
D-4D, 2000 to 2023
The 1KD-FTV is a 3.0 L (2,982 cc) straight-four common rail D-4D (Direct injection four-stroke common-rail Diesel) diesel engine with a variable nozzle turbocharger (VNT


the answer is buy your service manual from toyota.
Hylux means zero lacking year and country. zero.

the ECU is last never #1. ever. in fact it is good. and why replace the most expensive electric part on the car .
fuse are first, and sensors unplugged.
wow. that was brave.
gee did 1 spark fails or all 4? not doing all 4 is so wrong.
if all 4 die, CKP /CMP tests are next.
no turbo right? 2.0L DOHC chain drive, miles on it are?
wow fuses all good is first not $300 parts.
is this a USA car, not told why skip #1 important fact .????
in the USA we have OBD2 cars 1996 up. (our invention)
but not VOXY sold to ASIA, are you in ASIA market????????
and all scan tools here work at that DLC port.
and we scan it.
are you sure 1998 is correct wiki show 2001 up 2019
there are vast 1AZ engine even 1AZ-FE (fuel injected) up and VVT
or 1AZ-FSE?????
what is there ive not one clue. and lots of voxy submodels exist.
same car as the Toyota Noah

I see no 1998 on earth sold called that. why?
no country told and is not sold here USA.
i will make list of no spark, modern 1AZ-fe
random order.

1. cam does not turn or is timed wrong. chain snapped
2. cmp dead cam sensor dead or # 1 cause.
3. CKP crank sensor dead,
4. coil packs 2 of them or 4 COP's all dead.
5. bad wiring related;.
6. ECU bad, rare.

SOME 1AZ USE 4 COPS AND OTHERS USE 2COIL PACKS THAT RUN 2 SPARK PLUGS CALLED WASTED SPARK]
AND IF SAY SPARK#1 IS DEAD, IF SPARK 1 OR 4 SPARK PLUG OR HV WIRE IS OPEN BOTH DIED. DEAD. FOOLING YOU.
COP'S MEANS COIL OVER PLUG AND IS 4 SPARK COILS
AND ALL4 MUST BE TESTED OR GO WILDLY ASTRAY YOU WILL
THE ONLY 2.0 l 1AZ IN USE 1980 IS RAV 4.
SO YOU ARE NOT THERE. TIME TO BRAVE UP AND TELL

At the very least it indicates a bad head gasket that needs to be replaced. Once the cylinder head is removed then the actual cause of the gasket failure can be determined.

No pulse means computer is not getting something it wants. Do you have spark at plugs? Correct fuel pressure? Security system needs reset?

Cylinder Head
stg 1 = 40NM
stg 2 = 79NM
stg 3 = 90^
Main bearing
stg 1 = 20NM
stg 2 = 40NM
stg 3 = 90^
Big end bearing 25NM then 90^

no year, you are kidding,right?
mandatory, metal plate?
what year, what engine.
see here and see why we dont know.
like 20 engines there.

this is why we are clueless, that is ok 90% of posts never say.
2.0 L 1AZ-FE I4 (petrol)
2.0 L 1AZ-FSE I4 (petrol)
2.0 L 3ZR-FAE I4 (petrol)
2.2 L 2AD-FTV I4 (diesel)
2.2 L 2AD-FHV I4 (diesel)
2.4 L 2AZ-FE I4 (petrol)
2.5 L 2AR-FE I4 (petrol)
3.5 L 2GR-FE V6 (petrol)

on the side of the engine,
why do you need to know that.?
they never fail unless hit with a hammer.
the answer is in the FSM (no engine options stated so impossible to answer prefectly)
its at alldata.com, but you need engine size.
here is the engine list just for all (in year span) RAV4

2.0 L 1AZ-FE I4 (petrol)
2.0 L 1AZ-FSE I4 (petrol)
2.0 L 3ZR-FAE I4 (petrol)
2.2 L 2AD-FTV I4 (diesel)
2.2 L 2AD-FHV I4 (diesel)
2.4 L 2AZ-FE I4 (petrol)
2.5 L 2AR-FE I4 (petrol)
3.5 L 2GR-FE V6 (petrol)
world wide, and you never said what country either.

Yes.
D-4 is the type of fuel injection - direct injection.
vvt-i : Variable valve timing with intelligence.
It is used on Toyota's 2.0L first generation AZ engine family : 1AZ-FSE
1 - First gen
AZ - engine family
F - Economy narrow-angle valve DOHC
SE - Direct injection
Vehicles using the engine include Avensis, RAV-4, Premio, Wish and Allion

Thanks for your concern guy's. We did manage to fix the problem....It took us about four days of laborious work....We had to remove the harness covers and work our way backwards and forward, from the management computer, to and from the relevant 'sender unit' coolant temp, air temp, manifold pressure, lumda and oxogen sensor and from the controlled units, ie, ignition system, injection system, cooling fan set up and so on. We managed to identify the connections by following the identification labels printed onto the circuit boards.

We think that Toyota could make life a lot easier, if they used a standard wire colour coding and did not change that colour inside the loom....It is not un-common to see, as an example, a red with white tracer at one end and that may be joined to a blue with red tracer at the other end....If the loom cover is not removed and the cable inspected, you could not guess from what goes in, what will be coming out.

Hope this will be of help to someone somewhere.

Best regards
