P0228代码定义

Throttle/Pedal Position Sensor/Switch C Circuit High Input

P0228代码的意思是什么

P0228是一种通用OBD-II代码,表明节气门/踏板位置传感器/开关C电路具有很高的输入问题,导致传感器输入发动机控制模块(ECM)高于与冗余相比的预期电压输入节气门位置传感器A或高于指定范围。

是什么原因导致P0228代码?

  • ECM检测传感器电路电压是否高于传感器的指定范围

  • Short 5 volt reference to the signal wire could cause low voltage to the ECM. This can be from external wiring problems, or from an internally shorted sensor

P0228代码的症状是什么?

  • The Check Engine Light and Electronic Throttle Control (ETC) Light will be illuminated

  • The ECM goes into failure limp home mode; drive complaints may vary depending on manufacturer programming

  • 在停止期间,油门完全关闭,以防止RPM过度

  • 在加速期间,油门设置为固定位置,以限制油门开口

  • Uneven idle or jerking during braking, due to the closed throttle position

  • Limited acceleration due to very poor throttle response, or no response at all, during acceleration

  • Vehicle speed limited to 32 mph or less

  • 残疾巡航控制

机械师如何诊断P0228代码?

  • 扫描代码和记录冻结框架数据以验证问题

  • Clears the engine and ETC codes to verify whether the concern comes back

  • 对接线和与节气门身体传感器的连接进行直观检查,以进行短线或燃烧的电线,这可能会导致短暂的电源

  • 检查扫描数据以查看传感器信号电压是否短路到电源,并遵循精确测试步骤以找到短路

  • Disconnects and checks the sensor resistance to see if sensor short is internal

Common mistakes when diagnosing the P0228 code

遵循以下简单准则以防止误诊:

  • Do a visual check of the wiring to the sensor to make sure they are not shorted in any way

  • 寻找传感器烧伤或切线的任何问题,或连接中的腐蚀

P0228代码有多严重?

  • Any problems with the throttle sensor cause the limp mode to be activated

  • 发动机将进入li行的家庭模式,系统将受到限制,具体取决于制造商

  • The vehicle speed will be limited to less than 35 mph

  • The engine will lack acceleration or have limited acceleration

  • The engine idle will be low and erratic when coming to a stop

哪些维修可以修复P0228代码?

  • 修理或更换短线接线到传感器
  • 如果内部短路替换有缺陷的节气门控制组件
  • 更换或重新编程ECM如果通过精确测试来指导

Additional comments for consideration regarding the P0228 code

当信号到达ECM高于指定的信号时,触发代码P0228,可能是由于传感器和ECM之间的线束短线引起的。大多数制造商都不使用此代码,应遵循认可的精确测试。
