Check the resistance.

Using an ohmmeter, measure the resistance between the terminals.

Standard resistance

RESISTANCE BETWEEN TERMINALS

Tester Connection	Specified Condition
1 - 2	26 to 30 Ω at 20°C (68°F)

If the result is not as specified, replace vacuum switching valve No. 1.

Check vacuum switching valve No. 1 for ground.

Using an ohmmeter, check the resistance between each terminal and the body.

Standard resistance

BETWEEN EACH TERMINAL AND BODY

Tester Connection	Specified Condition
1 - Body	10 MΩ or higher
2 - Body	10 MΩ or higher

If the result is not as specified, replace vacuum switching valve No. 1.

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.
