4                Expected Result:The pressure that is measured with the pressure gauge for each step and the pressure that is displayed on the electronic service tool for each step are within 1379 kPa (200 psi).Results:
Yes - The injection actuation pressure sensor is operating properly. Proceed to Test Step 12.
No - The injection actuation pressure sensor may be faulty. Replace the sensor and repeat this test step. If the problem still exists, verify the accuracy of the pressure gauge. Reinstall the original sensor and proceed to Test Step 12.Test Step 12. Perform the "Injection Actuation Pressure Test" at both Low Idle and at High IdleStart the engine. Run the "Injection Actuation Pressure Test" at low idle and at high idle.Record the data in the following table.

Turn the engine off.
Remove the Injection Actuation Pressure Control Valve (IAPCV).
Install a 219-2368 Plug and 9X-1484 Seal Kit and perform the pressure test.
Disconnect the high pressure oil line from the cylinder head and install the
