Removal and Installation
YD25DDTi ENGINE MODEL
REMOVAL
1.Remove harness connector.
2. Loosen nuts, and remove accelerator pedal assembly.
CAUTION:
+Do not disassemble the accelerator pedal assembly. Do not remove the sensors and the switches
from the assembly.
+Avoid impact from dropping etc. during handling.
+Be careful to keep the assembly away from water.
+Do not adjust the adjusting screw (painted white) of the accelerator work unit.
+When the harness connector of the accelerator sensor is disconnected, perform ªAccelerator
Pedal Released Position Learningº. Refer to ªBasic Service Procedureº in EC section.
INSTALLATION
Install in the reverse order of removal.
INSPECTION AFTER INSTALLATION
+Check that the accelerator pedal moves smoothly within the whole operation range.
+Check that the accelerator pedal securely returns to the original position.
+For the electrical inspection of the accelerator work unit, refer to EC section, ªDTC 0403 ACCELERA-
TOR PEDAL POSITION SENSORº.
+Check that the drum of the accelerator work unit can be fully opened.

WARNING:
+Situate vehicle on a flat and solid surface.
+Place chocks at front and back of rear wheels.
+Do not remove engine until exhaust system has com-
pletely cooled off. Otherwise, you may burn yourself

+Be sure to hoist engine and transmission in a safe man-
ner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATA-
LOG.
CAUTION:
+When lifting engine, be careful not to strike adjacent
parts, especially the following: Accelerator wire casing,
brake lines, and brake master cylinder.
+In hoisting the engine, always use engine slingers in a
safe manner.
+For 4WD models, apply sealant between engine and
transmission. Refer to MT section (ªRemoval and Instal-
lationº).
+For tightening torque, refer to M/T and PD sections.
+Before separating engine and transmission, remove the
crankshaft position sensor (TDC sensor) from the
assembly.
+Always pay extra attention not to damage edge of crank-
shaft position sensor (TDC sensor) or ring gear teeth.
