RE: speed sensor
I found this I don't know if it will help or not??
Vehicle speed sensor, mounted in transaxle housing, is an
input device consisting of speed sensor rotor and speed sensor. Input
signal is delivered from speed sensor to TCM with each revolution of
axle shaft. TCM uses speed sensor input signal for controlling
transaxle operation.
VEHICLE SPEED SENSOR (VSS)
1) To check speed signal, connect measuring unit to TCM. (Part#93F73165) Raise and support front wheels of vehicle. Set shift lever to " N" position. Turn ignition on.
2) Connect voltmeter between measuring unit terminals No. 20
and 48. Battery voltage should be present. Block one front wheel and
spin other wheel rapidly. Voltage should be 4-7 volts. If voltage is
consistently high or low, check wiring for an open or short circuit.
If no fault is found, replace TCM.
3) To check speed signal wiring to instrument panel, connect
measuring unit to instrument panel 30-pin connector. Ensure ignition
is off. Using a DVOM, measure resistance between measuring unit
terminal No. 6 and TCM connector "B" terminal No. 18. See Fig. 10.
4) Resistance should be zero ohms. If resistance is not as
specified, check wiring circuit and repair as necessary. If resistance
is as specified, check for incorrect installation of wiring which may
cause interference, such as ignition wiring, mobile phone, etc.
