- 断开发动机转速/正时传感器的发动机转速/正时接头。 检查接头有无腐蚀、销弯曲、销或套筒丢失、导线不匹配或损坏。
- 将发动机转速/正时传感器从飞轮壳上取下。
- 检查传感器塑料端是否有磨损迹象或污染物，如金属屑。 发动机转速/正时传感器的塑料端不能有污染物。 发动机转速/正时传感器的塑料端也不能有距离表面超过 0.051 mm (0.0020 in) 的磨损。
- 使用螺丝刀小心撬开传感器的塑料端至完全伸展位置。 完全伸展位置超出传感器金属壳体大约 4.75 mm (0.187 in)。
- 抓住传感器的塑料端。 从一侧至另一侧晃动传感器以检查端隙。 不能有松动。
- 轻轻推入传感器的塑料端。 传感器的塑料端应当稳固。 传感器的塑料端应当能抵抗任何伸缩移动。 如果没有电阻，更换传感器。
- 为安装发动机转速/正时传感器，根据步骤 3 至步骤 6 中的检查说明检查传感器。
- 如果传感器端未完全伸展，使用螺丝刀小心撬开传感器的塑料端至完全伸展位置。 完全伸展位置超出传感器金属壳体大约 4.75 mm (0.187 in)。
注: 如果传感器滑头安装在正时齿圈上的槽中，则可能会导致传感器损坏。 安装前，确保传感器的安装孔中可看见正时齿圈的轮齿。
- 检查传感器螺纹底座处 O 形密封圈。 如果密封圈丢失或损坏，安装新的 O 形密封圈。
- 将发动机转速/正时传感器安装到飞轮壳体中。 将传感器上紧到 40 ± 5 N·m (29 ± 4 lb ft) 的扭矩。 尖端必须靠在正时参考环上。
- 连接发动机转速/正时传感器的接头。
注: 确保锁圈正确卡合。
注: 重新安装发动机转速/正时传感器之后，必须重新标定电子喷射正时。 请参阅故障诊断与排除, "发动机转速/正时传感器 - 标定"。
