INSPECTION

PROCEDURE

1. INSPECT VACUUM REGULATING VALVE ASSEMBLY

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection

Condition

Specified Condition

1 - 2

20°C (68°F)

11.1 to 12.5 Ω

If the result is not as specified, replace the vacuum regulating valve assembly.

(b) Check the operation of the vacuum regulating valve assembly.

(1) Using a vacuum pump, apply a vacuum of 67 kPa (503 mmHg, 19.8 in. Hg) to the port (F) and check that the vacuum regulating valve assembly operates normally.
