How to Read Flowcharts
A flowchart is designed to be used from start to final repair. lt's like a map showing you the shortest distance. But beware:
lf you go off the "map" anywhere but a "stop" symbol, you can easily get lost.
brARn
t.-OotO tw"t Describes the conditions or situation to start a troubleshooting flowchart.
FcTloNl Asks you to do something; perform a test, set up a condition etc.
@ Asks you about the result of an action, then sends you in the appropriate troubleshooting direction.
fS-OPl The end of a series of actions and decisions, describes a final repair action and sometimes directs you to
(bold type) an earlier part of the flowchart to confirm your repair.
NOTE:
. The term "lntermittent Failure" is used in these charts. lt simply means a system may have had a failure, but it checks
out OK at this time. lf the Malfunction Indicator Lamp (MlL) on the dash does not come on, check for poor connections
or loose wires at all connectors related to the circuit that you are troubleshooting (see illustration below).
. Most of the troubleshooting flowcharts have you reset the Engine Control Module (EcM)/Powertrain Control Module(PCM) and try to duplicate the Diagnostic Trouble Code (DTC). lf the problem is intermittent and you can't duplicate the
code, do not continue though the flowchart. To do so will only result in confusion and, possibly, a needlessly replaced
ECM/PCM,
o "Open" and "Short" are common electrical terms. An open is a break in a wire or at a connection. A short is an acci-
dental connection of a wire to ground or to another wire. ln simple electronics, this usually means something won't
work at all. In complex electronics (like ECM'S/PCM'S), this can sometimes mean something works, but not the way it's
suooosed to.

ldle Control System
Fast ldle Thermo Valve lA/T)
Description
To prevent erratic running when the engine is warming
up, it is necessary to raise the idle speed. The fast idle
thermo valve is controlled by a thermowax plunger.
When the engine is cold, the engine coolant surround-
ing the thermowax contracts the plunger, allowing addi-
tional air to be bvDassed into the intake manifold so that
the engine idles faster. When the engine reaches operat-
ing temperature. the valve closes, reducing the amount
of air bypassing into the intake manifold.

NOTE: The fast idle thermo valve is factory adjusted; it
should not be disassembled.
1. Remove the intake air duct from the throttle body.
2. Start the engine,
3. Put your finger over the lower port in throttle body,
and make sure that there is air flow with the engine
cold (engine coolant temperature below 86"F, 30'C).
lf there is no air flow, replace the fast idle thermo
valve and retest,

Start the engine. Hold the engine at 3,000 rpm with no
load (in Park or neutral) until the radiator fan comes
on, then let it idle.
Check that the valve is completely closed. lf the valve
is leaking, the idle speed will drop when you cover the
lower pon. Check the engine coolant level and for air
in the engine cooling system {see section 10). lf the
cooling system is OK, replace the fast idle thermo
valve and recheck.

Fuel Tube/Ouick-Gonnect Fittings
Procautions
@ Do not smoke whils working on the fuel
syst6m, Koop open flames away from your work ar9a.
The fuel tube/quick-connect fittings assembly connects
the in-tank fuel pump with the fuel feed pipe. For remov-
ing or installing the fuel pump and fuel tank, it is neces-
sary to disconnect or connect the quick-connect fittings.
Pay attention to following;
. The fuel tube/quick-connect fittings assembly is not
heat-resistant; be careful not to damage it during weld-
ing or other heat-generating procedures.
. The fuel tube/quick-connect fittings assembly is not
acid-proof; do not touch it with a shop towel which
was used for wiping battery electrolyte. R€place the
fuel tube/quick-connect fittings assembly if it came
into contact with electrolyte or somethino similar.
. When connecting or disconnecting the fuel tube/quick-
connect fittings assembly, be careful not to bend or
twist it excessively, Replace it if damaged,
A disconnected quick-connect fittings can be reconnected,
but the retainer on the mating pipe cannot be reused once
it has been removed from the pipe. Replace tha retainer

1. Disconnect the battery negative cable.
2. Remove the fuel fill cap to relieve fuel pressure in
the tank.
3. Relieve fuel pressure (see page 11-178).
4. Check the fuel quick-connect fittings for dirt, and
clean if necessary.
5. Hold the connector with one hand and press down
the retainer tabs with the other hand. then pull the
connector off.
NOTE:
. Be careful not to damage the pipe or other parts.
Do not use tools,
. lf the connector does not move, keep the retainer
tabs pressed down, and alternately pull and push
the connector until it comes off easily.
. Do not remove the retainer from the pipe; once
removed, the retainer must be replaced with a
new one.

Regulator Valve
The regulator valve maintains constant hydraulic pressure from the ATF pump to the hydraullc control system, while also
furnishing fluid to the lubricating system and torque converter. Fluid from the ATF pump flows through B and B'. Fluid
entering from B flows through the valve orifice to the A cavity. This pressure of the A cavity pushes the regulator valve to
the right side. and this movement of the regulator valve uncovers the fluid port to the torque converter and the relief
valve. The fluid flows out to the torque converter and the relief valve, and the regulator valve moves to the left side.
According to the level of the hydraulic pressure through B, the position of the regulator valve changes and the amount of
fluid from B,through the torque converter also changes. This operation is continued, maintaining the line pressure.
NOTE; When used, "|eft" or "right" indicates direction on the illustration below.
ENGINE NOT RUNNING
STATOR SHAFT ABM
Stator Reaction Hydraulic Pressurs Control
Increases in hydraulic pressure according to torque are performed by the regulator valve using stator torque reaction. The
stator shaft is splined to the stator in the torque converter, and its arm end contacts the regulator spring cap When the
vehicle is accelerating or climbing (Torque Converter Range), stator torque reaction acts on the stator shaft, and the stator
arm pushes the regulator spring cap in the direction of the arrow in proportion to the reaction. The stator reaction spring
compresses, and the regulator valve moves to increase the line pressure. Line pressure reaches its maximum when the
stator torque reaction reaches its maximum.
