最近一个月引擎灯已经断断续续地亮过三次了,基本上都是亮一天左右,然后当天晚上
或第二天就自动灭了。今天又再次亮了,而且液晶屏显示“engine power is reduced
”“service traction control”,于是去autozone 去查code:
Troubleshooting P2122
OEM Brand: General_Motors
Definition
Accelerator pedal position (APP) sensor
1 circuit
low voltage
Explanation
The
ECM has detected that the APP
sensor 1 voltage
is less than 0.25 volts
for less than 1 second
Probable cause
1. Poor electrical connection
2. Failed APP sensor
查完code后去了本地的一个听说比较便宜的mechanic shop去问,得到答复说是gas
pedal 和engine之间的communication有问题,就是踩油门可能不能提速,说要修的话
有可能需要把gas pedal 换了,大概500刀左右,请问班上的车友有类似的经历吗?
