Circuit Description
WARNING: This page is about a different variant/trim than selected.
Vehicle Speed Sensor (VSS) circuit is a magnetic induction type sensor. Gear teeth pressed on outside diameter of output shaft assembly induce an alternating current in sensor as shaft rotates. Signal goes directly to VCM. Pulsing action takes place about 40 times per revolution of output shaft of transmission and VCM will calculate vehicle speed based on time between pulses.
Conditions for setting DTC:
- No MAP sensor DTCs are set.
- Vehicle speed less than one MPH.
- Throttle angle less than 3 percent.
- ECT greater than 140°F (60°C).
- Engine speed 1400-4400 RPM.
- MAP pressure less than 20 kPa.
- Conditions are met for 5 seconds.
