Coolant Temperature Switch - Test
本步骤用来测试冷却液温度开关是否正常工作。 发动机运转时执行本步骤。
- 使用 6V-7070 数字万用表来测量冷却液温度开关的电阻值。 冷却液的温度为
50 °C (122 °F) 或更低时，从冷却液温度开关上断开导线接头。 - 将万用表的一根导线与冷却液温度开关的接头连接。 将万用表的另一根导线与冷却液温度开关的接地相连。
测量电阻。 电阻应为 54 ± 2 欧姆。
- 冷却液温度约为
120 °C (248 °F) 时重复上述步骤。 电阻不应小于 15 欧姆。 - 若冷却液温度开关的电阻不在给定电阻值范围，更换冷却液温度开关。
