Toyota Sienna: Isolating Rear AC lines?

This problem is very much noticed on many Toyota vehicles.After some years of usage the Rear Side A/C lines gets rusted and gets cracked.Replacing the lines is only option to get complete cooling.The cost to replace is A/C line assembly is approx $1500 including labor charges.
But there is no guarantee that this same problem will not reoccur after some years.

Mostly the problem is noticed on the lines going back from the front unit to the rear unit.


THE LINES TO THE REAR HAVE BEEN AN ISSUE EVEN THROUGH THE Present latest MODEL YEAR.

It is a corrosion issue and the muffler on this year has a tendency to rubber on the low side line and wear a hole in it. The fitting at the rear cooler unit is an issue also. The front can not be isolated by any conventional means. In theory you can just run the front which many repair techs will recommend.And that is correct. This would require someone that can weld aluminum efficiently. Up on the lines where they branch off from the front would have to be cut and crimped then welded over at the seam that was crimped. There would be no side affect it would just have to be charged with a little less Freon.So the line dont gets over-pressurized by ample of Freon.

This details will help.
Thanks.

2002 Toyota Sienna: Wipers and Passenger side Power window stopped working?

Wipers started a bit then stopped working and Passenger side window stopped working at same time.
But all other windows work properly.

This types of problem many a times makes the car owner to think,that problem is same for both the faults.
But its not the same.

It can be faulty fuse or issue with Motor.
To remove the fuse out needle nose are fine. The fuse holder is under the hood fuse box.
The pivot on the wiper motor for the rear is known to freeze. There is also a circuit breaker built into the rear motor that can get burned. Pull the motor and check the shaft. The 25 amp wiper fuse is the only fuse for the rear wiper.
The front window is not related to wiper not operating.The windows work off of the 30 amp power fuse and feeds all the windows not just the right front window. If the other windows work it is not a fuse issue and more then likely is a bad window motor. The fuse box has a lock tab to depress and the lid pops off.

So for both the cases the issue is most probably the faulty motor.The Wiper operating motor and power window motor.

Getting this parts checked and inspecting before directly replacing will help.
Thanks.

1999 Lexus LX470: DTC C1252 and C1256 Code Detected?

C1252 Code indicates Faulty Hydro-Boost pump and Code C1256 points towards accumulator pressure low.

These do not normally fail. Based on CODE description however it does sound like the accumulator has failed. When the pump runs continuous it means that is not building pressure so that it shuts off. The pump should cycle on to pressure up the system then cycle back off. It's a long shot but you could possibly have the technician flush the brake system by using the active testing scan tool to operate the pump and push fluid out all four wheels cylinders. If it will not consistently bleed hydraulic pressure while active testing with the tech view scan tool or similar scan tool then you're looking at a bad accumulator pump assembly.

Unfortunately your options are limited here. This code sets whenever electric pump in the Hydro system runs longer than it is designed to or supposed to. Its advisable to get this parts tested/ inspected with proper Professional  mechanic so the correct diagnosis can be done to confirm the problem.The parts cost is  heavy in such cases.The cost can go approx $4000 for replacing whole ABS cannister, computer and motors.
You might consider trying to find a used one otherwise you're at the mercy of Lexus and other high dollar pump assembly. It comes with the new accumulator computer and pump motor. Due to the complexity of this component none of the parts are available separate and they're not re-buildable.

This details will help you to understand the problem.So you follow the correct path in getting the parts checked, before getting this problem solved.

Thanks.

2008 Toyota Tacoma: ABS causes Brake pedal fade?

Soft or Spongy Brake Pedal when ABS not getting Activated.
Many Toyota Vehicle owners and other car owners having ABS system in the car have complained and noticed this problem.

Basically what happens in this problem,that Normal braking is perfect on Smooth pavement and brick roads.But on rough roads such as wash board type roads the Brake pedal gets soft and Driver has to apply complete/ more pressure to stop the vehicle.

On basis to Toyota Tacoma Truck vehicle models i will say that,These trucks are so light in the rear when on a bumpy road and applying the brakes the ABS will activate prematurely. Are you feeling the abs actuator motor come in and pulse the pedal. If this is the case there is not much you can do about it short of putting weight in the bed or disable the abs to see if this is what is going on.

Other Option is that ,You are experiencing premature ABS activation and your hearing the actuator pump activate and you can feel the brake pedal flutter.

But if this is not the case then i will say ,
The ABS is going to activate on any car that is on wash board type roads due to the tire being in a non contact situation with the road even if for a split second and if the brakes are being applied that one or more wheels will have a tendency to stop or slow faster then the rest of the wheels and the computer interprets this as sliding or skidding and will active the abs system. I get this complaint a fair amount when customers life on old brick roads. If there are no codes triggering the computer and the normal braking action is good with no pedal fade there is not much your going to be able to do with the wash board type problem. The only other thing that I have seen is if the rear shocks get bouncy which if they are the Bilstein shocks it will aggravate the problem even more on wash board type roads.


TO understand about how the ABS causes pedal fade.OR Why the ABS causes Soft Pedal.
Read the further details with more explanation:-----


When any of the wheel speed sensors detect a rotational deviation or different from the others it causes the actuator assembly to activate the pump motor which generates brake fluid pressure to the other wheels causing the wheels to brake which in turn causes a slight pedal fade for pulsation in the actual brake pedal itself. If you are not feeling this pulsation occurring or any buzzing from the actuator motor when this situation is occurring then it is not related to the ABS or actuator motor activation. Bumpy roads or washboard type roads should have no effect on the brake pedal travel unless the ABS is prematurely coming on. If you're feeling a soft or spongy pedal and the ABS is not activating then you have a hydraulic pressure problem. This possibly could be something intermittent in the master cylinder. However to correctly diagnose the problem you or your mechanic has to measure pedal pressure or distance traveled or fade. The bottom line is you need to determine whether not the ABS system is activating when you're noticing this problem.

This details will help.
Thanks.

Toyota Camry: Premature ABS Actuation?

The Brake Feeling like it grabs then grinds and this problem goes on repeating.

In this cases first inspect the master cylinder and confirm that its not the problem.
Generally getting premature ABS actuation. Normally this is caused by one of the wheel speed sensor speed rings. These rings are attached to each drive axle or the backside of each wheel bearing. Typically what happens is the little grooves you get cracked or get damaged due to rust or corrosion. This causes an erratic signal to be sent to the ABS computer which thinks that you're sliding on ice and prematurely activates the ABS system. The only way to detect this is to monitor all four wheel speed sensors on an oscilloscope and watch the pattern for anomalies. If there are no codes it's unlikely anything in the ABS control unit or the wheel speed sensors themselves.

This details will help.
Thanks.

2006 Toyota Sienna: How to replace Rear Spark Plugs?

Replacing spark plugs on toyota sienna.The Rear Spark plugs are behind the Intake plenum.Getting hands there is bit difficult.
You have two options here. The first one is to just remove the throttle body from the plastic intake manifold. This will give you a little more access to reach in and under the intake manifold itself. It still is tight but can be done. In order to remove the intake manifold to replace the spark plugs the wiper motor panel assembly and upper cowling has to be removed before the intake manifold will come off.
The plastic manifold itself has three brackets on the backside by the firewall which are very tight tolerances to unbolt then you have the obvious bolts along the top of the manifold that hold the manifold to the lower aluminum housing.

The throttle body comes off in two sections the first one is held on by either three or 4 -10 mm bolts then the second section is held on with about four to five 12 mm bolts. Given the age typically these rubber gaskets can be reused. The intake manifold is slightly different but basically the same when it comes to the throttle body configuration depending on whether you have the 3.3 L or the 3.5 L engine. In 2006 depending on your production you could have either engine.

This details will help.
Thanks.

2008 Toyota Highlander: Symptoms after Jumper Cables Crossed?

This is not Advisable.The Jumper cable crossed will cause lots of shorting issues.Tracing the exact problem takes lots of time in some cases.
Basically in some cases,you will see that vehicle will drive only in idle but will give no response on throttle.

The first thing that gets affected by this is,it normally just blows fuses. The large 120 amp ALT fuse.
If there is no throttle response more than likely you also popped the 10 amp or possibly 15 amp ETCS fuse look in the fuse box under the hood and locate this fuse. This is the main power feed for the drive by wire throttle motor. If there's no throttle response most of time of the time you will find that this fuse is blown.

Typically when these are jumped backwards like this it only blows fuses it rarely does any damage to engine control computer's.. Replace it see how it drives then check for any other components that are not operating and inspect the rest of the fuses.
If you notice any other problem after that,then in most cases the check engine light will come ON steady.Whenever the check engine light illuminates by default the vehicle skid control light comes on also.

This details will help.
Thanks.
