Measure the resistance according to the value(s) in the table below.

Standard resistance

Tester Connection	Condition	Specified Condition
1 - 2	Cold	1630 to 2740 Ω
1 - 2	Hot	2065 to 3225 Ω

TEXT IN ILLUSTRATION

*a	Component without harness connected (Crankshaft Position Sensor)

HINT:

Terms "cold" and "hot" refer to the temperature of the coils. "Cold" means approximately -10 to 50°C (14 to 122°F). "Hot" means approximately 50 to 100°C (122 to 212°F).

Reconnect the crankshaft position sensor connector.

NG → See step 6

OK: Go to next step

CHECK HARNESS AND CONNECTOR (CRANKSHAFT POSITION SENSOR - ECM)

Disconnect the crankshaft position sensor connector.
Disconnect the ECM connector.

Measure the resistance according to the value(s) in the table below.

Standard resistance

Check for open

Check for short

Tester Connection	Condition	Specified Condition
B21-1 - B51-6 (NE+)	Always	Below 1 Ω
B21-2 - B51-5 (NE-)	Always	Below 1 Ω

Tester Connection	Condition	Specified Condition
B21-1 or B51-6 (NE+) - Body ground	Always	10 kΩ or higher
B21-2 or B51-5 (NE-) - Body ground	Always	10 kΩ or higher

Reconnect the ECM connector.
Reconnect the crankshaft position sensor connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (CRANKSHAFT POSITION SENSOR - ECM)

OK: Go to next step

  OK
  
  Sensor is installed correctly.
NG → See step 7

OK: Go to next step
CHECK CRANKSHAFT POSITION SENSOR PLATE (TEETH OF SENSOR PLATE)
1. Remove the crankshaft position sensor plate, refer to DISASSEMBLY .
2. Check the teeth of the sensor plate.
  OK
  
  Sensor plate does not have any cracks or deformation.
3. Reinstall the crankshaft position sensor plate, refer to REASSEMBLY .
NG → See step 8

OK → See step 5
