Current Sensor Removal/Installation: Notes
WARNING: This page is about a different car, the 2014 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- If the nut for the current sensor is loosened with the negative battery cable terminal connected to the battery, excessive torque will be applied to the negative battery cable terminal and the battery terminal will be damaged. When removing the negative battery cable terminal and current sensor, be careful not to damage the battery terminal.
- Be careful not to contact the positive battery cable terminal.
- Disconnect the current sensor connector before disconnecting the negative battery cable terminal. If the negative battery cable terminal is disconnected first, the PCM may mistakenly recognize a signal from the current sensor causing interference with engine control.
