2. 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

   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).

3. Reconnect the CKP sensor connector.

NG → REPLACE CRANKSHAFT POSITION SENSOR 

OK: Go to next step

2. Disconnect the E3 ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard resistance (Check for open)

   Tester Connection	Specified Condition
   E9-1 - NE+ (E3-32)	Below 1 Ω
   E9-2 - NE- (E3-31)	Below 1 Ω

   Standard resistance (Check for short)

   Tester Connection	Specified Condition
   E9-1 or NE+ (E3-32) - Body ground	10 kΩ or higher
   E9-2 or NE- (E3-31) - Body ground	10 kΩ or higher

4. Reconnect the ECM connector.
5. Reconnect the CKP sensor connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Check the CKP sensor installation.

   OK

   Sensor is installed correctly.

NG → REPAIR OR REPLACE CRANK POSITION SENSOR 

OK: Go to next step 

1. Check the teeth of the sensor plate.

   OK

   Sensor plate does not have any cracks or deformation.

NG → REPLACE CRANKSHAFT POSITION SENSOR PLATE 

OK → REPLACE ECM
