2. 2
   Disconnect the injector connector.
3. 3
   Measure the resistance between terminals 1 and 2 of the injector.
4. 4
   Check that the resistance is within specification.

   Specification: 1.5 ± 0.075 [20 °C]

DEPOSIT

1. 1
   Release the residual pressure in the fuel line. (Refer to Fuel System - "Fuel Line Residual Pressure Release".)
2. 2
   Turn the ignition switch to the OFF position and disconnect the negative (-) battery terminal.
3. 3
   Remove the fuel tube and injector assembly. (Refer to Fuel System - "Fuel Hose".)
4. 4

REMEDY

1. 1
   Combustion Seal
2. 2
   rubber washer
3. 3
   Retaining disc
4. 4
   O-ring

1. To install, perform the removal procedure in reverse order.

REPLACEMENT

1. 1
   Remove the combustion seal (A) using cutting pliers.

   

2. 2
   Before installing the seal, clean the groove with a clean cloth. Carefully remove the sealant from the sealing surface of the injector using a copper wire brush.

   

3. 3
   Place the seal installation guide (B) (SST No: 09353-2B000) onto the injector tip without damaging the injector tip (A). Press the O-ring (C) onto the conical fitting with your thumb and index finger until it enters the groove. The complete assembly should take no more than 2-3 seconds.

   

   

4. 4
   To measure the O-ring size, first fully insert the injector into the installation tool (A) (SST No: 09353-2B000), then press and simultaneously rotate it 180° in the gauge tool.

   

5. 5
   Remove the injector from the tool by rotating it in the opposite direction during pressing.
6. 6
   Check the installation of the combustion chamber seal (A).
