Jeep 4.0L VSS
22 March 2007Vehicle Speed Sensor
All engines from ‘91 and up make use of a speed sensor to send the speedometer signal to the computer. 87-90 Renix systems did not use a vehicle speed sensor.
‘91-96 OBD I
While a VSS is part of the factory system, it is not clear how important this component is to the system. With a manual PCM, the engine will still run and drive.
- Cable-driven speedometers on CJs and SJs require a 7/8″ thread
- There is a stock speed sensor that provides the 91-96 VSS signal and mechanical 5/8″ output:
- Wells SU3008 [pic]
- Niehoff SN7005 [pic]
- Mopar 56027015
- An adapter is available toconnect this 5/8″ thread VSS to 7/8″ speedo cable [ ? ]
