INPUT/TURBINE SPEED SENSOR INSPECTION [AY6A-EL, AY6AX-EL]

id0517k3298300

  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.
  • Do not damage the terminals.

On-Vehicle Inspection

1. Disconnect the negative battery cable.

2. Remove the fresh-air duct and air cleaner component as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

3. Remove the TCM. (See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)

4. Measure the no continuity between coupler component terminals B12 and GND, B13 and GND.

  • If there is any malfunction, inspect the coupler component for continuity. (See COUPLER COMPONENT INSPECTION [AY6A-EL, AY6AX-EL].)
  • If the coupler component is normal, perform an off-vehicle inspection of input/turbine speed sensor. (See Off-Vehicle Inspection.)

B13—GND | No continuity

5. Measure the continuity between coupler component terminals B12 and B13.

Off-Vehicle Inspection

1. Connect the input/turbine speed sensor terminal B to the battery positive terminal, connect the battery negative terminal to input/turbine speed sensor terminal A through an ammeter set to a resistance of 100 ohm.

  Note
  • Inspect with a tester that can indicate more than 10 megohms and confirm that the value is more than 1 megohm.

2. Measure the current while waving a magnet back and forth over the top of the input/turbine speed sensor (less than 5 mm {0.2 in}).
