Toyota Tacoma (2015-2018) Service Manual: Inspection
INSPECTION
PROCEDURE
1. INSPECT OIL CLEARANCE
|
(a) Using a micrometer and caliper gauge, measure the oil seal clearance. Text in Illustration
Standard clearance: 0.021 to 0.043 mm (0.0008 to 0.0017 in.) Maximum clearance: 0.07 mm (0.0028 in.) If it is greater than the maximum, replace the vane pump assembly. |
|
2. INSPECT VANE PUMP ROTOR AND VANE PUMP PLATE
|
(a) Using a micrometer, measure the height, thickness and length of the vane pump plates. Text in Illustration
Minimum height: 7.7 mm (0.303 in.) Minimum thickness: 1.408 mm (0.0554 in.) Minimum length: 11.993 mm (0.4722 in.) |
|
|
(b) Using a feeler gauge, measure the clearance between a side face of the vane pump rotor groove and vane pump plate. Text in Illustration
Maximum clearance: 0.025 mm (0.0012 in.) If it is greater than the maximum, replace the vane pump assembly. |
|
3. INSPECT FLOW CONTROL VALVE
(a) Coat the flow control valve with power steering fluid and check that it falls smoothly into the flow control valve hole under its own weight.
|
(b) Check the flow control valve for leakage. Close one of the holes and apply compressed air of 392 to 490 kPa (4.0 to 5.0 kgf/cm2, 57 to 71 psi) to the hole on the opposite side. Confirm that the air does not flow out of the end holes. Text in Illustration
If necessary, replace the vane pump assembly. |
|
4. INSPECT COMPRESSION SPRING
|
(a) Using a vernier caliper, measure the free length of the spring. Text in Illustration
Minimum free length: 36.9 mm (1.453 in.) If it is not within the specification, replace the vane pump assembly. |
|
5. INSPECT PRESSURE PORT UNION SUB-ASSEMBLY
(a) If the union seat in the pressure port union sub-assembly is badly damaged, it could cause fluid leakage, so replace the vane pump assembly.

Yaw Rate Sensor (C1A46)
DESCRIPTION
If the millimeter wave radar sensor assembly receives a yaw rate sensor malfunction
signal from the yaw rate sensor (airbag sensor assembly) or yaw rate sensor zero
point malfunction signal from the skid control ECU (master cylinder solenoid)*1
or skid control ECU (brake actuator ...

1. DATA LIST
HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful because intermittent conditions or signals ...
