Crankshaft Position Sensor: Testing and Inspection
Eccentric Shaft Position Sensor Inspection
ECCENTRIC SHAFT POSITION SENSOR INSPECTION
NOTE: Before performing the following inspection, make sure to follow the troubleshooting flowchart. (See FOREWORD.) See: Powertrain
Management/Computers and Control Systems/Testing and Inspection/Initial Inspection and Diagnostic Overview/Foreword
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 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 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
