My Toyota Auris 2010 has loss of engine power

[Laski]

My Toyota Auris 2010 1.6 engine manual drive with 140k m/h has been stalling and lost engine power. The max it would go while trying to speed is 40m/h. I’ve been to the mechanic and he said it’s the clutch, after changing the clutch, problem persists. It didn’t bring any check light on the dashboard. We checked with a machine and discovered the U011B error. I’ve read about it saying it’s the Valvematic controller but I just want to be sure if the problem will stop after I’ve changed the controller. Also, who knows what model number will suit my Toyota Auris 2010 1.6engibe manual drive. 
Thanks

The U011B code generally indicates a loss of communication with the "A" Camshaft Profile Control Circuit. This can often be caused by a malfunction within the Valvematic system, which could potentially explain the loss of power that you're experiencing with your Toyota Auris.

The Valvematic system in Toyota cars is designed to improve fuel efficiency and CO2 emissions by controlling the intake valve lift volume and timing of intake valve opening and closing, and if there's a failure in this system, it can certainly cause power loss.

However, it's also important to keep in mind that the U011B error code can be caused by several other things, including:

Faulty electrical connections in the camshaft profile control circuit wiring
Damaged or corroded connectors or pins within the camshaft profile control circuit
Faulty engine control module (ECM)
Faulty camshaft position sensor
As such, while replacing the Valvematic controller might resolve the issue, it's also possible that the problem lies elsewhere within the camshaft profile control circuit.

Regarding the model number for the Valvematic controller, I'd suggest getting in touch directly with a Toyota dealership or a reputable parts supplier. They should be able to provide you with the exact part number based on your vehicle's specifications. Make sure to have your Vehicle Identification Number (VIN) at hand as it will likely be needed to ensure you receive the correct part.

If the problem persists even after replacing the Valvematic controller, you may want to consider further diagnostic testing to pinpoint the issue. You might need to investigate those other potential causes for the U011B code I mentioned. This might involve checking the circuit wiring and connectors for any signs of damage or corrosion, as well as potentially testing the ECM and the camshaft position sensor.

Keep in mind this is an educated guess based on the information provided. For a comprehensive diagnosis and repair, it's best to rely on a certified mechanic or technician

Thanks for your input. I’m just worried and scared I don’t want to spend a lot on the Valvematic controller and still the problem persists. It seems most of the auto technician over here in Portsmouth doesn’t even know how to handle the issue. I’ve been to about 3 garages.

Hi, 

As you have shared the mechanic has changed  the clutch although it may never needed a new clutch. The problems you have indeed are about the vvti controller , it is a common fault on these cars from these years and an expensive fix. There are many more posts about this issue from before. Some people went for used one from lower mileage cars and newer years. 2012 for example, the problematic yers are as far as I know 2010-2011. 
Usually a mechanic should know what they are working on. If not then, you may need to look for another place, dealer or Toyota specialist. I know its not cheap and unfair I don’t know what to suggest to you. 
Good luck

I’m actually thinking of going for a used one as well but my worry is if a 2012 model will work for it. Do I’ve to let the mechanic take it out of the engine so I can check the model number that’s inscribed on it or what? I’m just confused.

Hi, 

you can use this side https://japancars.ru/index.php?route=catalog/toyota

to find any part numbers you need and search for the part. Find your car model and engine type and the part in question. You can also visit a dealer to speak to parts department for price availability and part number too, even if you don’t want to buy from them.

Finally I got a used Valvematic from eBay and threw it in the car. Car worked perfect and when we scanned, the error P1047 still appeared, the technician cleared the error and it didn’t come back on. My car drives perfect now and I hope this error doesn’t come back.  Thanks everyone.

Hello 

Well I had similar issue not too long ago.. my car has power loss as it would not speed over 20-30m/h. The technician wasn’t sure what was wrong, he asked me to put in a new clutch which I did, problem repeated itself. I came online and found it’s a popular issue with the 2010/2011 Toyota Auris. I changed my Valvematic and car works perfect now. 

[Laski]

May I ask what symptoms are your car giving or is it driving fine?

sometimes it goes slowly and the fuel consumption has increased a bit.

Next week change valvematic.

 

and P2648?

Yes

You may check with a mechanic but it’s most likely the Valvematic controller. It’s a general problem with the Auris 2010/2011. It cost about 1300pounds from the Toyota shops so you may want to try eBay. That’s where I got mine from and so far the car is working fine.
