ECCENTRIC SHAFT POSITION SENSOR INSPECTION

BHE014018221W01

  Note

  • Before performing the following inspection, make sure to follow the troubleshooting flowchart. (See Troubleshooting Procedure.)

## Visual Inspection

1. Remove the eccentric shaft position sensor.

2. Verify that there are no metal shavings on the sensor.

  • If the monitor item condition (reference) is not within the specification even though there is no malfunction, perform the "Circuit Open/Short Inspection".

## Resistance Inspection

1. Disconnect the eccentric shaft position sensor connector.

2. Measure the coil resistance between eccentric shaft position sensor terminals A and B.

  • If not within the specification, replace the eccentric shaft position sensor.
  • If the monitor item condition/specification (reference) is not within the specification, even though the eccentric shaft position sensor resistance is within the specification, perform the "Circuit Open/Short Inspection" and repair or replace the malfunctioning part.

  Eccentric shaft position sensor resistance
  950-1,250 ohms (at room temperature)

## Circuit Open/Short Inspection

1. Disconnect the PCM connector.

2. Disconnect the eccentric shaft position sensor connector.

3. Inspect the following wiring harnesses for open or short circuit. (Continuity inspection)

### Open circuit

  • If there is no continuity in the following wiring harnesses, there is an open circuit. Repair or replace the wiring harness.
  – Eccentric shaft position sensor terminal A and PCM terminal 2U
  – Eccentric shaft position sensor terminal B and PCM terminal 2X

### Short circuit

  • If there is continuity in the following wiring harnesses, there is a short circuit. Repair or replace the wiring harness.
  – Eccentric shaft position sensor terminal A and body ground
  – Eccentric shaft position sensor terminal A and power supply
  – Eccentric shaft position sensor terminal B and body ground
  – Eccentric shaft position sensor terminal B and power supply
