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
the flowchart, To do so will only rosult in confusion and, possibly, a ne€dlessly replaced ECM
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-
poSad to,

The Fuel Injectors a.e a solenoid-actuated constant-stroke pintle type consisting of a solenoid, plungel n€edle valvs and
housing. When cur.ent is applied to the solsnoid coil, the vslve litts up and pressurized fuel is injected. Because the nee-
dle valve litt and the luel pressure are constant, the iniection quantity is determined by the length of time that the valv€
is open (i.e., the duration the cu.rent is supplied to the solenoid coill. The Fu€l Iniector is sealed by an O-ring and seal
ring at the top and bottom. These seals also reduce operating nois6.

Clearance Inspection
NOTE: lf replacement is required. always replace the
synchro sleeve and the synchro hub as a set.
1. Measure the clearance between 2nd and 3rd gears.
Standard: 0.06 - 0.21 mm {0.002 - 0.008 inl
Ssrvica Limit: 0.3 mm (0.01 in)

Service Limit34.8 mm
(1.370 in)
34.3 mm(1.350 in)
2. lf the clearance is more than the service limit, mea-
sure the thickness of 3rd gear.
lf the thickness of 3rd gear is less than the ser-
vice limit, replace 3rd gear with a new one.
lf the thickness of 3rd gear is within the service
limit, replace the 3rd/4th synchro hub with a new
one.
3RD GEAR

Measure the clsarance betw€en,lth gear and the
soacer collar.
St.ndffd: 0.06 - 0.21 mm (0.002 - 0.(xt8 in)

5. lf distance O is not within the standard, replace the
spacer collar with a n€w one. lf distance @ is within
th€ standard, measure the thickness of 4th gear.
lf the thickness of 4th gear is less than the ser-
vice limit, replace 4th gear with a new one.
lf the thickness of 4th gear is within the service
limit, replaco the 3rdl4th synchro hub with a new
one.

or the threaded section of the ball ioint pin might be
damag6d by the balljoint remover.
10. Use th€ ball joint remover, 28 mm, as shown onpage 18-11. to separate the ball joint and lower arm.
