(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)

6.2 to 8.2 Ω

If the result is not as specified, replace the oil pressure control valve assembly.

(b) Connect a positive (+) lead from the battery to terminal 1 and a negative (-) lead to terminal 2.

Check that a clicking sound is heard from the oil pressure control valve assembly.

NOTICE:

  • Check that the battery voltage is between 10 and 16 V before performing this test.
  • Perform this test within 10 seconds to prevent the coil from burning out.
  • Always switch the voltage on and off at the battery side, not the oil pressure control valve assembly side.
