If any of the specified value's were Not obtained:
-- Replace the Charge Air Pressure Sensor 2 / Intake Manifold Temperature Sensor 2 - G447 / G430-. Refer to appropriate Service Information.
-- Go to Final procedures.
If the specified values were obtained:
-- Replace the Engine Control Module -J623 -. Refer to appropriate Service Information.
Final procedures
-- Reinstall the engine cover with air filter, if necessary. Refer to the appropriate Service Information.
-- After the repair work, the following work steps must be performed in the following sequence:
- Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY .
- If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
- If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
