ls DTC P1498 indicated?
Check for an open in tho EGRvalv6 lift sen3or:1. Turn the ignition switch OFF.
2. Disconnect the EGR valve lift
sensor 3P (M/T: 6Pl connector.
3. Turn the ignition switch ON (ll).
4. Measure voltage between the

12, Install the steering joint cover with the clamps and a
clrp.
Reconnect the tie-rod ends to the steering knuckles,
tighten the castle nut ('96 -'97 models) or nut ('98 -
'OO models) to the specified torque, and install new
cotter plns.
NOTE: Before connecting the tie-rod ends, wipe off
any grease contamination from the ball joint tapered
section and threads.
CAUTION: Torquo the castle nut to the lower torque
sp€cification, then tighten it only tar enough to align
the slot with the pin hole. Do not align the nut by
loosening {,96 -'97 models only).

Install the exhaust pipe A or TWC (see section 9).
Connect the shift linkage (see section 13 or section
14).
lnstall the front wheels
Fill the system with power steering fluid, and bleed
air from the system (see page 17-331
After installation, perform the following checks
. Start the engine, allow it to idle, and turn the
steering wheel from lock-tolock several times to
warm up the fluid. Check the gearbox for leaks
(see page 17-39).
. Adjust the front toe (see section 18).
. Check the steering wheel spoke angle. Adjust by
turning the right and left tie-rods, if necessary.
NOTE: Turn the right and left tie-rods equallv
