VSV For Vapor Pressure Sensor: Inspection

REMOVE VSV
INSPECT VSV
1. Inspect VSV for open circuit.
  Using an ohmmeter, check that there is continuity between the terminals.
  
  Resistance: 30 - 36 Ω at 20°C (68°F)
  
  If there is no continuity, replace the VSV.

2. Inspect the VSV for ground.
  Using an ohmmeter, check that there is no continuity between each terminal and the body.
  
  If there is a continuity, replace the VSV.
