Speed Sensor Wiring


Recommended Posts

Kevin I have a FSM for the 83 and I'm sorry I do not see the VSS connecting to the ECM control unit.

The VSS is generated in the speedometer head unit.

Exits as a yellow with red tracer wire from terminal 45 on the speed-0 conntector.

It is used for the CC and the TC but does not appear to be an ECM input.

Could it be a late build date 83, making it an 84?

Hope someone has a better answer.

is the speedo itself working? tjhe sensor is in the instrument cluster, and is for things like cruise control

 

so if speedo isnt reading, check the cable. my 83 wagonhad cruise

 

on jims sedan, he accidentally pulled away the speedo cable while changing heater hose, thus resulting in no speedo, and a VSS code on the ecu

Checked for code in BAT auto

 

22 --- Ignition pulse system (1983 only)/Vehicle speed sensor or circuit or VLC solenoid valve or circuit. (1984 to 1988 carbureted)

 

checked mine from the board's repair manual

 

1983

22 --- Ignition Pulse System

 

1984

22--- Vehicle Speed Sensor (VSS) or Circuit

 

Is it an automatic?

 

Wasn't the change to hyd lifters made between 83 and 84?

On the automatic cars??

 

What colors are these wires ?

 

If nobody else comes to the rescue, I'll dig out my 84 FSM and see what it says.

 

Your welcome
