故障现象:一辆2014款丰田RAV4,SUV越野车,自动变速器,行驶15 000km,客户反映踩下加速踏板无任何反应,无法加速行驶。故障诊断与排除:笔者接车后首先验证故障现象,踩下加速踏板没反应,打开发动机盖,发现电子节气门也无任何反应。但发动机启动、怠速均正常,发动机故障灯也未点亮。笔者连接故障诊断仪,经检测无任何故障码储存。由于笔者所在汽修厂规模较大,恰好有同款车型,为尽快解决故障,笔者随即调换了加速踏板,但故障依旧。紧接着,笔者又调换了电子节气门,仍无法解决问题。

Troubleshooting and troubleshooting: The first car after the test to verify the phenomenon of failure, did not press the accelerator pedal, open the engine cover and found no reaction of the electronic throttle. But the engine starts, idle speed are normal, engine failure lights did not light. The author connected to the fault diagnostic apparatus, the test without any fault code stored. As the author where the auto repair plant larger, just have the same models, as soon as possible to solve the problem, I immediately replaced the accelerator pedal, but the fault still. Then, I also replaced the electronic throttle, still can not solve the problem.
