我的丰田花冠2005现在开始感到非常地沉重,…

欢迎来到JustAnswer机械支持!我amCustomerand今天我将调查和支持你的问题。我的理解真的很令人沮丧,当你的汽车并非工作预期但别担心我在这里帮助!我可能需要进一步的信息,然而,如果需要我会让你知道!抱歉听到你与你的车有问题,我将尽力帮助你。* * P0741 * *是一种很常见的OBDII故障代码。这是知道影响经常* *丰田卡罗拉* *。意味着什么:P0741:液力变矩器离合器电路→性能或卡了卡罗拉使用离合器在发动机和液力变矩器锁定在高速公路的速度传播。P0741可以注册在这个连接不正常发生或者发生。P0741不会影响你的丰田卡罗拉发动机的方式执行。 It is purely a transmission related code. Although, the engine response may “feel” different without the torque converter locking. It’ll be at a higher RPM, which means The vehicles PCM (Powertrain Control Module) will throw the P0741 trouble code in the Corolla if there is a difference that is **greater than 200 rpm** between the transmission input shaft and the torque converter speed. This is standard for any Toyota vehicle made on or after the 1996 model year. With P0741, the code gives you two reasons as to why the code has registered. They are: - **Performance** – The clutch, like all clutches, is failing. - **Stuck Off** – Somewhere in the Corolla’s wiring, there is an error that is keeping the TCC from engaging. More often than not, this is going to be the issue. With this knowledge, there can only be so many things that are causing the P0741. We’ll discuss them directly below. Toyota Corolla P0741 Diagnosis These are the most common problems that can cause the P0741 in the Corolla: - **Bad Torque Converter Lock up Solenoid** – The solenoid that allows the torque converter to lock up is often the culprit. Here’s a good video on how to [diagnose and repair the TCC Solenoid](https://www.youtube.com/watch?v=XzniUfjK6Aw). This can be a tough problem for the shade tree mechanic to deal with. It involves a lot of checking for circuit resistance and testing the wiring. That being said, it sure doesn’t hurt to follow the wiring and see if you can find any noticeable issues. Here’s how to use a scanner to diagnose it: - **Bad Torque Converter Clutch** – The clutch itself can go bad, just like a manual transmission. The good news is that when this clutch goes out the transmission will still take you to where you need to go. Even if it does so at a slightly higher RPM. - **Short in the TCC** – A short in the wiring going from the TCC to the TCM can cause the P0741. - **Bad TCM** – The transmission control module itself can be the cause of P0741 in your Corolla. Although, it’s probably not going to be the first place that you should check. The wiring should be the first place that you should check, as it will most likely be the problem. - I think it could be a faulty torque convertor but would need diagnosing by a transmission specialist.
