Test

To prevent component damage:
• Use connector test adaptor kit J 35616-A.
• When applying 12 V to a component,

always use a 3 A fused wire.

Resistance Check

1

Using a digital ohmmeter and connector test adaptor
kit J 35616-A, measure the resistance across
terminals 1 and 2.

2

Compare the reading against the specification.

3

If the resistance is not within specification, replace the
EVAP canister purge valve.

Functional Test

1

Attempt to blow air through the EVAP canister purge
valve inlet port (1). If air passes through the valve, the
valve is faulty and should be replaced.
