Just ran a diag, got a few codes.

If someone could inform me what they are, that would be most kind.

ABS: 71 72 73 74 75 76 77 78. *Car was not running.

SUS -NG: 73 82 83 84 85 91 92 93. *Car was not running.

TRC NG: - -

ECT NG: 63


Thanks :-)

Just read that code 63 is the #2 solenoid in the trans...

What issues does a faulty #2 solenoid cause usually?
Is this the cause of my slow acceleration, even when shifting into first?

Also, what will it cost to fix?

A Faulty #2 Solenoid can cause issues starting off in the wrong gear, skipping gears, not kicking down into correct gear and slow acceleration from stand-still.

You may have old codes showing that may still not apply so remove your battery clamp for a few minutes and plug it back in and take the car for a good drive in different areas and different speeds then re-check

Here is a list of suspension codes :

Bingo Boris!

-slow accel
-not kicking down

That's my exact issue right now.
So - solenoid 2 will be replaced ASAP.
Also, turns out the other codes were just because the car wasn't started and run round the block. Everything is fine aside from code 63. :-)


Thanks!

Get a mechanic to take a look at it?

Well that's the thing.
Each mechanic to have touched this car so far have made it worse and or done absolutely nothing to fix it. Toyota won't even touch it down here.

I've had two throttle position sensors, both misaligned by mechanics, i had a speaker whine which was said to be the headunit, and wasn't.
So that caused issues and stalling around.
I also had some dunce tell me the power steering pump has no vacuum lines - whilst he was staring straight at the thing.
Mechanics are dumb as hell over this side of the city - they all seem to be highschool drop outs.

The last time I went to see why fuel was leaking - the dude said "oh your return line is obviously blocked" and said he needs to drain the tank. or what not. What a joke.
Turned out to be the fuel filler restrictor coming loose. $10 to fix.

A mechanic should be like a doctor - not a dunce.

I've worked out everything myself - with the help of you guys of course. Car is getting better weekly.

So, will call a trans place next week, see how much it's gonna cost for a check or new solenoid and so on.

Strangely, the car still selects all gears.
It goes 1/2/3/OD. Kicks down. Sometimes it won't kickdown however. I can still hit 7000rpm or what not.

From a stop in first gear, it takes off in First, it's just slow to gain speed - almost as if not getting enough fuel.

I can tell it's in first, as when pulling up at the lights in 2, you shift to 1, and the gear changes. So i assume it's also taking off in 1, when stick is in 1st position.

Error code #63 = solenoid #2.

Just curious - Is this most likely a real trans error?
Could a bodge alternator or ECU have caused this error? (some people say they had the error and it was a loose wire! - hopefully that's my issue)
Think the alternator is on the way out...
ECU might be also on the way out...
Trans seems fine - smooth - just has lack of launch power...

Getting the ECU capped next week, so that's one thing out of the way.
I'm reading the forums about code 63 so may answer my own questions shortly :-)

Rob, get the ECU done, then check out the trans, if it still feels the same.

From what i've read Rob, it could be 1 of 3 things.

1. loose wire.
2. bad harness/short.
3. actual solenoid issue.
4. unsure if ECU could cause it, but it probably can.

I have no idea from real life xp though, this is just what i've read. You probably already read this also!

Hi Rob.

You are considering many of the issues that could cause the error code, which is good. You need to know and understand how the electrical system of the transmission fully works.

In case of a solenoid, it's a coil that when powered creates a magnetic field to open a valve or orifice. The solenoid is earthed by the body of the transmission, and powered and triggered by the ECU.

The reason to explain this is so you can further understand the questions your asking here. Yes a loose connection can cause the issue, or severed wiring harness. The solenoid itself can be shorted, or have a bad contact inside due to manufacturing fault causing intermittent operation. A bad earth can also cause it.

You can measure the complete resistance of the circuit by starting at the ECU Pin and earth of the battery, and compare with the other solenoids as a reference. You can test the resistance of the wire itself by testing from the ECU Pin to the plug on the solenoid. You can then measure the resistance of the solenoid itself and also power it up, but keep in mind this testing may not simulate a fault condition when actually running in car, such as heat so keep this in mind if your issue is only intermittent which a lot of times it is.

As the ECU Itself is part of the circuit that supplies power to the solenoid, this in itself can cause a fault.

You have very high expectations of mechanics, this is not a problem as we all like to have the best for our cars. The issue in reality is this is not true. A large number of mechanics are high school dropouts or losers, but that being said there is some very clever mechanics out there and these are in 2 Categories

The only issue is the majority of mechanics are in the $20/hour Pay-scale region, so you cannot expect a Mechanic to have the same Skill-Set, care, enthusiasm, forward thinking, motivation and precaution as a doctor, lawyer or president.

You mention also that Mechanics have been wrong in telling you what is the issue with the car. Even the best mechanics get it wrong sometimes, there is just so many different causes to faults and answers you get are based on experience.

They often rely on common knowledge from previous faults so working on rarer cars like Soarers is going to be an issue with some faults they give.

If you want higher class service you need to find yourself a specialist, perhaps somebody who has experience on Toyotas of this Era and somebody who can work in his own time. Other than that you need to learn how to diagnose and fix your car yourself.

I often had the same issue as you Rob, so I learned how to do everything myself.

Hi Boris - great insight there, thanks a lot.
Currently waiting on an ECU repair, then will do the solenoid!

I now also have error 84 (front right suspension too high) ...

Sigh.

Will be back when fixed! :-)
