Q: High RPM's when slowing down or coming to a stop

on2018年2月14日

I have a 2009 Chevy traverse LS with 110K miles.This is happened 4-5 times.. when I am driving my traverse either at a stop or trying to slow down my RPM will go way high. I push on the brake and it is like my car is fighting the brake and trying to go fast. i will pull of the side of the road and turn it off that sometimes helps other times when I start up I press on the gas and brings down the RPM. I went to a mechanic and he said it is a computer chip that works with the transmission for shifting. The part was $800 and labor was $700. they replaced the apart and a week later and it happened again. Any idea??

这是一个常见的问题,即节气门位置传感器失败,因为它在关闭车辆时倾向于重置自身,这就是为什么您可能会注意到它在关闭汽车并重新启动汽车时会消失。这节气门位置传感器monitors the throttle position of the throttle plate inside the throttle body in relation to your foot position on the gas pedal. Based upon the inputs from the sensor reading your foot’s position on the pedal, the ECU then makes the direction to supply more or less fuel to the motor. When this sensor is not working properly, this can cause intermittent responses when pressing the gas pedal.

这re are trouble codes that are typically associated with the TPS. One code will set if the TPS voltage is too high when the computer expects to see it lower. Another code will set if the TPS voltage is lower than the computer expects to see. The TPS code for low voltage is the most common and will usually set if the TPS is out of adjustment or the sensor has failed. The first thing you should do when you get a TPS code is to check adjustment and signal output of the TP sensor before replacing it. Be sure to wiggle all connections while watching scan data/voltage readout to make sure the problem is not a loose or bad connection.

在节气门位置传感器失败的情况下可能会发生某些情况,这些传感器可能无法设置故障代码。失败的TPS最常见的症状之一就是犹豫不决,或者当您使用油门从停车场起飞时跌跌撞撞。这可能是由TP传感器内部电路中的一个死点引起的,这通常会导致输出电压信号在油门打开时不会更改(或掉落)。我建议您让您的机电专家来您的位置诊断和检查您的车辆。万博体育入口
