Inspection
INSPECTION
PROCEDURE
1. INSPECT CRANKSHAFT POSITION SENSOR
(a) 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 |
| Hot | 2065 to 3225 Ω |
HINT:
In the table above, the 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).
If the result is not as specified, replace the crankshaft position sensor.
Installation
INSTALLATION
PROCEDURE
1. INSTALL CRANKSHAFT POSITION SENSOR
(a) Clean and remove any oil from the threads of the crankshaft position sensor installation bolts.
(b) Apply adhesive to 2 or 3 threads of the bolt.
Adhesive:
Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent.
(c) Apply a light coat of engine oil to the O-ring.
(d) Install the crankshaft position sensor with the bolt.
Torque:
10 N·m {102 kgf·cm, 7 ft·lbf}
NOTICE:
- When reusing the crankshaft position sensor, check the O-rings.
- Make sure that the O-ring is not cracked or jammed when installing to the timing chain cover assembly.
- Replace with a new part if it is dropped or if it receives a strong impact.
(e) Connect the crankshaft position sensor connector.
