Checking the Resistance of the Valve

Checking The Resistance Of The Valve







Take a resistance reading between

1 - Boost pressure control valve
2 - Boost pressure control valve

The reading should be 2 Ohm - 4 Ohm

Checking the wiring harness.
Jiggle the leads and in-line connectors at several places and in different directions to reveal intermittent breaks and short circuits in the wiring harness. Observe the multimeter, test lamp or diagnostic tool while doing this.

Is the function correct?

NO - Changing Components - II

YES - Continue With Checking The Resistance Of The Valve
