  1. REMOVE VSV 
  2. INSPECT VSV 
    1. Inspect the VSV for open circuit.

      Using an ohmmeter, measure the resistance between the terminals.

      Resistance: 30 to 36 Ω at 20°C (68°F)

      If the result is not as specified, replace the VSV.

    2. Inspect the VSV for ground.

      Using an ohmmeter, check that there is no continuity between each terminal and the VSV body.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
