Mazda 2: Input/Turbine Speed Sensor

INPUT/TURBINE SPEED SENSOR INSPECTION

CAUTION:

• Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.

On-Vehicle Inspection

1. Disconnect the input/turbine speed sensor connector.

1. Disconnect the negative battery cable.
2. Disconnect the input/turbine speed sensor connector.

2. Measure the resistance between the input/turbine speed sensor terminals A and B.

• If there is any malfunction, replace the input/turbine speed sensor. (See INPUT/TURBINE SPEED SENSOR REMOVAL/INSTALLATION).

Input/turbine speed sensor specification

• 250-600 ohms

INPUT/TURBINE SPEED SENSOR REMOVAL/INSTALLATION

CAUTION:

• Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.
• Always use a new bolt. If the removed bolt is reused, it may cause oil leakage.
• A sealant coating is applied to the input/turbine speed sensor installation bolt to prevent oil leakage from the installation bolt hole which passes through the component.
• If foreign materials are stuck to the sensor, disturbance by magnetic flux can cause sensor output to be abnormal and thereby negatively affect control. Make sure that foreign materials such as iron filings are not stuck to the sensor during installation.

1. Disconnect the negative battery cable.

2. Remove in the order indicated in the table.

3. Install in the reverse order of removal.

1. Connector
2. Input/turbine speed sensor
3. O-ring
