1. Check the Air Intake System
1. Check in accordance with "6.[1] AIR INTAKE SYSTEM
INSPECTION PROCEDURE". (Refer to page 1-S285)
IMPORTANT
• If the two errors occur from "Emergency exhaust gas
temperature sensor T0 high", "Emergency exhaust gas
temperature sensor T1 high", and "Emergency exhaust gas
temperature T2 high" at the same time, check the exhaust
gas temperature starting from a bigger number.
NOTE
• Check the clogging condition of the air cleaner. If it is very
dirty, replace the new one.
• Check if the suction hose of the turbo blower does not
come off. If the hose comes off, install it.
• Check the suction path for leaks. (Suction path joints,
suction pipes, hoses)
• Check the clogging condition of the fuel filter. If it is very
dirty, replace the new one.
• Check the installation of all exhaust gas temperature
sensors (T0, T1 and T2).
• Check the engine oil level.
• Check the engine coolant level.
