Toyota RAV 4 problem just happened overnight

So, as I have said before, one of the great things about owning a garage. Importantly, there is a diversity of jobs that we can encounter. Hence, in any busy working week,. This past week was no exception. One of our lady customers called it with her car, a Toyota RAV 4 !

Alarmingly, the reason was that the car was performing badly when trying to overtake. Especially when she put her foot down, the car was very slow to respond.

She had a new Duel Mass Flywheel fitted about six months ago ! Interestingly,  she had wondered if this could have anything to do with the car’s recent problem?

The Toyota RAV 4 was fitted with the 2.0D-4 D engine. Importantly, she had not experienced many engine problems in the past. In fact, apart from the clutch, the car had been trouble-free.

Ryan road tests the car ! Toyota RAV 4 Poor Acceleration Problems

Ryan, our workshop manager, took the car out for a test drive. So he noticed that the engine warning light was also illuminated . So on his return, he plugged the car into our diagnostic machine. I found that the code PO627 came up. When we looked up the code fault on our diagnostic site,. Then it stated that the problem could be a couple of things.

  1. The internal fuel was below the target fuel pressure that it should be, despite the engine ECU opening the Suction Control Valve (SCV)
  2. Fuel blockage.

Toyota RAV 42.0 D Engines are fitted with a Denso electronic high-pressure fuel pump.  Controlling the fuel rail pressure and the volume of fuel are both replaceable items. Denso also make the Fuel Pressure Regulator (we call it the SCV) that can cause power problems with the Toyota RAV4

Problems.

Ryan suspected it to be the SCV, and this was confirmed by a quick phone call to a friend of ours who specialises in diesel engines and fuel pumps. He told us that the SCV valves had given him the most problems with this particular RAV 4 engine fault, and so we took it upon ourselves to tackle this particular problem.

A new SCV ordered for the Toyota RAV 4: Toyota RAV 4 Poor Acceleration Problems

We contacted the customer with a price. Reluctantly, she gave us the go-ahead to carry out the necessary work on the car’s engine. We could only buy the SCV parts from the Toyota dealership. Unfortunately, they were not available from any of the local factors.

The first part of the job was to remove the two bolts that fasten the radiator expansion tank to the car. Allowing you more room to work. Importantly, you can see this in the picture the arrow is pointing to ! Where the fuel pump is located. Down near the yellow dipstick top. Ryan then had to remove the air intake/inter-cooler pipe.

The only difficult thing that Ryan could see was the location of the pump and where the SCV’s were located; they were located at the back of the pump, making the job a little fiddly.

When the new Toyota RAV 4 valves arrived,. Hence, they were both coloured differently. So, one was green and the other red. It was important that the new ones fit where the old ones had come from.

Hence the colour coding.

The valves are held into the pump by two heavy duty Allen screws each and were eventually freed by using an heavy duty Allen key type bit that fitted into an impact wrench set, with an extension tube to give him some leverage. This did the trick and the screws finally gave in to the pressure.

An important thing to watch out for is that the valve seats have two O-rings. These O-rings must be replaced and refitted into the valve seats; Ryan lubricated them when fitting them back, before the new valves were fitted back onto the pump.

Possible loss of fuel ! Toyota RAV 4 Poor Acceleration Problems

Another observation is that you will lose a small amount of fuel when doing this job, so protect the immediate area of the pump with some old cloth to soak up the diesel that comes out and you will not make a mess on the rest of the engine or the garage floor. We also thought it would be worth fitting a new fuel filter, and so we did.

When Ryan completed the work

he then re-set the Toyota RAV 4 engine diagnostic trouble codes , with our engine diagnostic machine and it then only took a couple of attempts to re start the engine. Because there would have been a little trapped air in the system from when the valves were removed. If you are doing this job at home inn one of these vehicles, we do recommend that you keep everything as clean as possible and do not let any dirt or other contamination onto the new valves.

The job only took about an hour

Including the ordering of the parts. Later the car was road tested and found to be cured of the problem. Happily, our lady customer picked up the Toyota RAV 4 paid us and went on her way a happy customer.

This problem can also be found on the following Toyota models

Clutch Vibration Problem

TOYOTA AURIS TD comes in for a Clutch Vibration Problem

So, for some unknown reason.  Christmas time brings in a few cars that are having Clutch Vibration problems. Hence, these are the normal problems. So, such as the driver cannot get the gears. Or the gears grind. Thus, when trying to drive the car and so on.

The Toyota Auris was a slightly different clutch pedal vibration and noise problem. As a result, the car was sort of vibrating and rattling. Consequently, as it was been driven along. When speaking to the customer. Ryan Linton my workshop manager. Discovered that the car had only had a new clutch fitted about two years ago. So the customer found it highly unlikely. Hence, that the clutch could be causing the clutch vibration in first gear problem. Especially, when driving the car along.

Ryan explained that the only way to tell is to check the clutch pedal vibration when engaging problem for the Clutch Vibration vibration when letting off clutch, by stripping the housing off and taking a look. The customer agreed and he took one of our courtesy cars while we explored his car to see what the problem was.

The other clutches that were done this week were standard sort of jobs,

taking two or three hours to do, but we always check with our Auto-data computer system, for the times it takes to do these jobs and this Toyota was shown to take seven hours, this included the Duel mass Flywheel having to be changed, but at this stage we did not exactly know what was wrong with the car.

Clutch Vibration Problem

Ryan, tripped down the Auris clutch housing and assembly. Only to find that the system was a Duel Mass Flywheel. To clarify, the car had only had the clutch fitted two years ago and nothing had been done to the Dual Mass Flywheel. This action had

caused the pressure plate and the Dual Mass Flywheel to wear prematurely. Causing the DMF to have more play in it. Therefore causing the Clutch Vibration.

We did not fit the first clutch.

However the customer said that he would not go back there again. The cost was estimated at about the £1000.00 mark. Of course, customer gave us the go ahead to do the job. The time given by Auto-Data was pretty accurate and it took Ryan near enough six hours to complete the job. We always fit LUK clutches and DMFs because they were the company who originally developed the products along with BMW in Germany and to date we have never had any warranty problems with the LUK products in the past.

The Toyota Auris clutch and DMF was finished, tested and returned to a happy customer another job well done by my excellent staff.
