Replacement
CAUTION: While replacing the speed sensor, be sure not to allow dust and other foreign parliclos to enter into the trans-mission.
'1. Disconnect the connectors for the drive pulley, the driven pulley, and the secondary gear shaft speed sensor.
2. Remove the 6 mm bolt from the transmission housing, and remove the drive pulley. the driven pulley, and the sec-ondary gear shaft speed sensors.
3. Replace the O-rings before reinstalling the drive pulley, the driven pulley, and the secondary gear shaft sp€ed sen-sors.

Pressure Testing
. While testing, be careful of the rot8ling front wheels.
. M8k6 suro lifts, iacks, and satety stands are placed properly lsee section 11.
CAUTION:
. Before testing, be sur. the transmb3ion fluid is fillod to the propor lcvel.. Warm up the engin€ to nolmal operating tsmperature bofore testing. While t€sting, be 3ure not to allow dust and other loreign particles to onler into the transmi$ion.
1. Raise the front of the vehicle, and support it with safety stands (see section 1).
2. Set the parking brake. and block both rear wheels securely.
3. Allow the front wheels to rotate freely.
4. Warm up the engine (the radiator fan comes on), then stop arid connect a tachometer.
5. Connect the special tool to each inspection hole.
TOROUE: 18 N.m (1.8 kgt'm, 13 tbtfr)
GAUTION:
. Connect the oil pressuro gauge !!€curoly, bs sur6 not to allow dust and other foroign particlG3 to ontar the inspsc-tion hole.
. Whon troubleshooting by tho E indicltor light indic.t6 a problam. you mu3t u3e an oil p.essure gluge that moa,sures 4,9(X) kPa (a.90 MPa,50.0 kS cr*,771psi) or more when molsuring driv. pulley pressure and driven pullcypre33ure.
NOTE:
. D.ive pulley pressure may be above 3,430 kPa (3.i8 MPa,35.0 kgf/cmr, 498 psi) wh€n there is a transmission prob-
lem that causes the TCM or PCM to go into the fail-safe mode,. Use a commercially available oil pressure gauge that measures 4,900 kPa {4.90 MPa, 5O.O kgf/cmr, 711 psi) ormore, and the Ay'T Oil Pressure Hose, 2210 mm (07MAJ - PY4011A).
