Code 24 - Vehicle Speed Sensor: Notes
NOTE:
Test numbers refer to numbers on diagnostic chart.
- Code 24 will set if VSS signal circuit voltage is constant, engine speed is 1200-4400 RPM, TPS indicates throttle near idle position, transmission not in Park or Neutral and all conditions met for at least 4 seconds.
- A voltage of less than one volt at instrument panel connector indicates VSS signal circuit wire may be shorted to ground. Disconnect signal wire at VSS buffer. If voltage remains less than 10 volts, circuit is shorted to ground or open. If circuit is not open or shorted to ground, check for poor control module connection and faulty control module.
