Inspection

  1. Inspect fuel injector assembly

Toyota RAV4. Inspect fuel injector assembly


  1. Measure the resistance between the injector terminals.

Standard resistance: 11.6 To 12.4 ٠at 20°c (68°f)

If the result is not as specified, replace the injector.

  1. Inspect the injector injection.

Caution:

Keep the injector away from sparks during the test.

  1. Connect sst (fuel tube connector) to sst (hose), then connect them to the fuel pipe (vehicle side).

Sst 09268-31011 (09268-41500, 90467- 13001, 95336-08070)

  1. Install the o-ring to the fuel injector.
