2001 NISSAN PICK-UP transmission

DescriptionNEEC1003The specification (SP) value indicates the tolerance of the value that is displayed in ªDATA MONITOR (SPEC)º
mode of CONSULT-II during normal operation of the Engine Control System. When the value in ªDATA MONI-
TOR (SPEC)º mode is within the SP value, the Engine Control System is confirmed OK. When the value in
ªDATA MONITOR (SPEC)º mode is NOT within the SP value, the Engine Control System may have one or
more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not light the
MI.
The SP value will be displayed for the following three items:
+B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board cor-
rection)
+A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)
+MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)
Testing ConditionNEEC1004+Vehicle driven distance: More than 5,000 km (3,107 miles)
+Barometric pressure: 101.3 kPa (1,013 mbar, 760.0 mmHg, 29.92 inHg)±3 kPa (30 mbar, 22.5 mmHg, 0.89
inHg)
+Atmospheric temperature: 20 - 30ÉC (68 - 86ÉF)
+Engine coolant temperature: 75 - 95ÉC (167 - 203ÉF)
+Transmission: Warmed-up*1
+Electrical load: Not applied*2
+Engine speed: Idle
*1: For A/T models, after the engine is warmed up to normal operating temperature, drive vehicle until ªFLUID
TEMP SEº (A/T fluid temperature sensor signal) indicates less than 0.9V. For M/T models, drive vehicle for 5
minutes after the engine is warmed up to normal operating temperature.
*2: Rear window defogger switch, air conditioner switch, lighting switch are ªOFFº. Cooling fans are not oper-
ating. Steering wheel is straight ahead.

Inspection ProcedureNEEC1005NOTE:
Perform ªDATA MONITOR (SPEC)º mode in maximum scale dis-
play.
1. Perform ªBasic Inspectionº, EC-3086.
2. Confirm that the testing conditions indicated above are met.
3. Select ªB/FUEL SCHDLº, ªA/F ALPHA-B1º and ªMAS A/F
SE-B1º in ªDATA MONITOR (SPEC)º mode with CONSULT-II.
4. Make sure that monitor items are within the SP value.
5. If NG, go to ªDiagnostic Procedureº, EC-3120.

SEF505U
Component DescriptionNEEC0272The vehicle speed sensor is installed in the transmission. It con-
tains a pulse generator which provides a vehicle speed signal to
the speedometer. The speedometer then sends a signal to the
ECM.
ECM Terminals and Reference ValueNEEC0273Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

DTC Confirmation ProcedureNEEC0275CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If ªDTC Confirmation Procedureº has been previously conducted,
always turn ignition switch OFF and wait at least 5 seconds before
conducting the next test.
TESTING CONDITION:
This procedure may be conducted with the drive wheels lifted
in the shop or by driving the vehicle. If a road test is expected
to be easier, it is unnecessary to lift the vehicle.

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
and/or fire may break out in fuel line.
+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
