Toyota Tacoma (2015-2018) Service Manual: Inspection
INSPECTION
PROCEDURE
1. INSPECT FRONT OIL PUMP BODY SUB-ASSEMBLY
|
(a) Using a dial indicator, measure the inside diameter of the front oil pump body sub-assembly bushing. Maximum inside diameter: 38.138 mm (1.50 in.) If the inside diameter is more than the maximum inside diameter, replace the front oil pump body sub-assembly. |
|
2. INSPECT STATOR SHAFT ASSEMBLY
|
(a) Using a dial indicator, measure the inside diameter of the stator shaft assembly bushing. Maximum inside diameter: 22.227 mm (0.875 in.) If the inside diameter is more than the maximum inside diameter, replace the stator shaft assembly. |
|
3. INSPECT CLEARANCE OF OIL PUMP ASSEMBLY
|
(a) Push the front oil pump driven gear to one side of the front oil pump body sub-assembly. |
|
(b) Using a feeler gauge, measure the clearance.
Standard body clearance:
0.10 to 0.17 mm (0.00394 to 0.00669 in.)
If the body clearance is more than the standard clearance, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly.
|
(c) Using a feeler gauge, measure the clearance between the front oil pump driven gear teeth and the front oil pump drive gear teeth. Standard tip clearance: 0.07 to 0.15 mm (0.00276 to 0.00590 in.) If the tip clearance is more than the standard clearance, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly. |
|
|
(d) Using a steel straightedge and a feeler gauge, measure the side clearance of both gears. Standard side clearance: 0.03 to 0.05 mm (0.00118 to 0.00196 in.) If the side clearance is more than the standard thickness, check the front oil pump drive gear, front oil pump driven gear and front oil pump body sub-assembly. |
|
4. INSPECT OIL PUMP DRIVE GEAR ROTATION
(a) Install the oil pump assembly to the torque converter assembly.
|
(b) Check that the front oil pump drive gear rotates smoothly. |
|
(c) Remove the oil pump assembly from the torque converter assembly.

Pressure Control Solenoid "C" Performance (Shift Solenoid Valve SL3) (P0796)
SYSTEM DESCRIPTION
The ECM uses the vehicle speed signal and signals from the transmission revolution
sensors (NT, SP2) to detect the actual gear (1st, 2nd, 3rd, 4th, 5th or 6th gear).
The ECM compares the actual gear with the shift schedule in the ECM memory to
detect mechanical problems of t ...
Precaution
PRECAUTION
CAUTION:
The vehicle is equipped with SRS, which consists of a driver airbag,
front passenger airbag, side airbags and curtain shield airbags and knee
airbags. Failure to carry out service operations in the correct sequence
could cause the SRS to unexpectedly deploy ...

FAIL-SAFE CHART
1. FAIL SAFE OPERATION
If there is a problem with any sensor signals or hydraulic brake booster
systems, the skid control ECU prohibits the power supply to the actuator
in the hydraulic brake booster and informs the ECM of VSC system failure.
The hydraulic brake b ...
