NOTE:
a Tha tarm ,,lntormittgnt Failure" is used in these chans. lt simply means a system may have had a failur6, but it chocks
out OK !t this time. lf th6 Msltunction Indicator Lamp (MlL) on ihe dash does not come on, check for poor connections
or loose wires at all connectors rolated to the cilcuit that you are troubleshooting (see illustration b6low).
a Most ot tho troublashooting flowchans have you reset the Engine Control Module (ECM) and try to duplicate the Disg-
nostic Troubls Cod6 (DTC). lf the problem is intermittent and you c8n't duplicat€ the cod6, do not continus through

a ,,opon,'and ,,short,, are common electrical terms. An open is a break in a wir6 or at a conn€ction. A short is an
accidontal connaction ot a wir€ to ground or to another wire. In simple electronics, this usually means som€thing won't
work at all. In complex electronics (like ECM's), this can sometimes mean something wolks, but not the way it's sup-

Differential pressure is generated by the numerous grooves around the impellers.

lf tuel flow is obstructed at the discharge side of the tuel line, the relief valve will open to bypass the

Throttle Body
Description
The throttle body is ot the single-barrel side-draft 1ype.
The lower portion of the throttle valve is heated by en-gine coolant from the cylinder head. The idle adjusting
screw which increases/dec.eases bvDass air and the
Evaporative Emission (EVAP) Control Canister port are
located on the top of the throttle body.

CAUTION: Do not adiust the thlottle stop screw. lt ispreset at the lactory.
1. Start the engine. Hold the engine at 3,OOO rpm with
no load (A/T in S or E position, M/T in neutral) until
the radiator fan comes on, then let it idle.
2. Disconnect the vacuum hose (to the EVAP control
canister) from the top of the throttle body; connect
a vacuum, gauge to the throttle body.

3. Allow the engine to idle and check that the gauge
indicates no vacuum.
a li there is vacuum, check the throttle cable (see
page 1 1-'l 18, 119).
Check that vacuum is indicated on the gauge when
the throttle is opened slightly from idle.
a lf the gauge indicates no vacuum, check the throt-
tle body port. lf the throttle body port is clogged.
clean it with carburetor cleaner.
Stop the engine and check that the throttle cable
operates smoothly without binding or sticking.
a lf there are any abnormalities in the above steps,
check for:
- Excessive wear or Dlav in the throttle valve shaft.
Sticky or binding throttle lever at full close po-
srtron.
Clearance between throttle stop screw and throt-
tle lever at tull close Dosition.

CAUTION: Betore t€sting, be sure the transmission fluidis tilled to rh6 ploper l€vet.
1. Raise the car (see section i),
2. Warm up the engine {the cooling fan comes onl, thenstop the engine and connect a tachometer.
3. Connect the oil pressure gauge to each inspectionholels).

Troubleshooting
Noise and Vibration
NOTE: Pump noise in first 2 - 3 minutes after starting in cold weather (-20.C, -4"F or colder) is normal.
Humming
Rattle or chattering
Right cylinder end soal squeak
Pump noise. though not loud,lrom the vslvo bodv unit can be heard when turn-ing the steering wheel right or left. This is normsl.
Humming due to pulsation ol fluid is no.mal, paniculady when wheel is turnedwith ca. stopped.
lf equipped with automatic trans-mission, the hum could b€ tor-que convener or pump notse.
Confirm by temporarily removingpump b€lt.

Loose steering shaft connector.tie-rod, or balljoint.Check and tighten, or replacepa s as necessary.
Column shaft wobbling.Replace column assembly.
Check the rack guide for properadjustment (16o page 17-21).Adjust, if n€ca€ssry.
Rattling sound and feeling when turning the steoring wheel right and lett with thoengine OFF is a sound when th6 valve unit contacts tho stopper. This is normal.
Striking sound wh6n turning the ste€ring whoglfully right o. left is a sound whenthe r6ck end contacts th6 stopper. This is normal.
