INSPECTION
INSPECT FUEL TANK AND LINE
(a) Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.
(b) Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks fuel leakage
or tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and tube connections are as shown in the illustra- tion.
If a problem is found, repair or replace the part as necessary.

SFI MASS AIR FLOW (MAF) METER
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT MAF METER RESISTANCE
Using an ohmmeter, measure the resistance between terminals
THA and E2.
Between
terminalsResistanceTemperature
THA − E210 − 20 kΩ−20°C (− 4°F)
THA − E24 − 7 kΩ0°C (32° F)
THA − E22 − 3 kΩ20°C (68° F)
THA − E20.9 − 1.3 kΩ40°C (104° F)
THA − E20.4 − 0.7 kΩ60°C (140° F)
THA − E20.2 − 0.4 kΩ80°C (176° F)
If the resistance is not as specified, replace the MAF meter.
2. INSPECT MAF METER OPERATION
(a) Connect the MAF meter connector.
(b) Using a voltmeter, connect the positive (+) tester probe to
terminal VG, and negative ( −) tester probe to terminal E3.
(c) Blow air into the MAF meter, and check that the voltage
fluctuates.
If operation is not as specified, replace the MAF meter.
(d) Disconnect the MAF meter connector.

THROTTLE BODY
ON−VEHICLE INSPECTION
1. INSPECT THROTTLE BODY
(a) Check that the throttle linkage moves smoothly.
(b) Check the vacuum at each port.
Start the engine.
Check the vacuum with your finger.
Port nameAt idleAt 3,500 rpm
PNo vacuumVacuum
ENo vacuumVacuum
RNo vacuumVacuum
2. INSPECT THROTTLE POSITION (TP) SENSOR
(a) Disconnect the TP sensor connector.
(b) Apply vacuum to the throttle opener.
(c) Using an ohmmeter, measure the resistance between
each terminal.

conditionBetween terminalsResistance
Fully closedVTA − E20.2 − 5.7 kΩ
Fully closedIDL − E22.3 kΩ or less
OpenIDL − E2Infinity
Fully openVTA − E22.0 − 10.2 kΩ
−VC − E22.5 − 5.9 kΩ
(d) Reconnect the TP sensor connector.
3. INSPECT AND ADJUST DASHPOT
(a) Allow the engine to warm up to normal operating tempera-
ture.
(b) Check the idle speed.
Idle speed: 650 ± 50 rpm (N position)
(c) Open the throttle valve until the throttle lever separates from the dashpot end.
(d) Release the throttle valve gradually, and check the dash-
pot setting speed when the throttle lever touched the
dashpot end.
Dashpot setting speed: 2,200 ± 300 rpm

If not as specified, adjust using the following procedure:
(1) Stop the engine.
(2) Loosen the lock nut of the stopper bolt.
(3) Adjust the dashpot setting speed by turning thestopper bolt.
(4) Start the engine and check the dashpot setting speed.
(5) Retighten the lock nut.
(e) Maintain the engine at 3,500 rpm.
(f) Release the throttle valve, and check that the engine re- turns to idle in a few seconds.
4. CHECK THROTTLE OPENER
(a) Disconnect the vacuum hose from the throttle opener, and plug the hose end.
(b) Check the throttle opener setting speed. Throttle opener setting speed: 700 − 1,000 rpm
If the throttle opener setting is not as specified, replace the
throttle body.
(c) Stop the engine.
(d) Reconnect the vacuum hose to the throttle opener.
(e) Start the engine, and check that the idle speed returns to the correct speed.
Idle speed: 650 ± 50 rpm (N position)
