DTC 31, DTC 32, DTC 33 & DTC 34: SPEED SENSOR CIRCUIT
Circuit Description
Speed sensor detects wheel speed and sends appropriate signals to ABS ECU. These signals are used to control
ABS system. Front and rear sensor rotors each have 48 teeth. When rotor rotates, magnetic field emitted by
permanent magnet in speed sensor generates an AC voltage. Since frequency of this AC voltage changes in
direct proportion to speed of rotor, frequency is used by ABS ECU to detect speed of each wheel. If
malfunction occurs in speed sensor circuit, ABS ECU cuts off current to ABS control relay and prohibits ABS
control.
DTC Detecting Condition
Detection of any of the following conditions may set DTCs 31-34:
Vehicle speed is 6 MPH or more and pulses are not input for 30 seconds.
Momentary interruption of speed sensor signal occurs at least 7 times during one ignition cycle.
Abnormal fluctuation of speed sensor signals when vehicle speed is 12 MPH or more.
Diagnostic Procedure
NOTE: To determine which speed sensor circuit is malfunctioning, see DTC

TORQUE CONVERTER
ONE-WAY CLUTCH TEST
1. Insert a turning tool into inner race of one-way clutch. Install Tester (09350-32014) so that it fits in notch
of converter hub and other race of one-way clutch.
2. With torque converter in normal operating position, clutch should lock when turned counterclockwise and
should rotate freely and smoothly when turned clockwise. See Fig. 7
. If one-way clutch fails test in either
direction, clean converter. Retest clutch. If clutch fails test, replace converter.

CONVERTER SLEEVE RUNOUT TEST
1. Temporarily mount torque converter to drive plate. Mount a dial indicator with needle resting on
converter sleeve. See Fig. 8
. Rotate converter. If runout exceeds .012" (.30 mm), ensure converter is
properly mounted to drive plate.
2. If converter is properl
y mounted and runout exceeds specifications, replace torque converter. Mark NOTE: Torque converter is a sealed unit and must be serviced as complete assembly.
Perform following tests to check converter condition. Torque converter and oil
cooler lines must be thoroughly cleaned and flushed if transaxle fluid is
contaminated.
