1. Check the Air Intake System
1. Check in accordance with "6.[1] AIR INTAKE SYSTEM
INSPECTION PROCEDURE". (Refer to page 1-S320)
IMPORTANT
• If the two errors occur from "Emergency exhaust gas
temperature sensor T
0
high", "Emergency exhaust gas
temperature sensor T
1
high", and "Emergency exhaust gas
temperature T
2
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 turbocharger 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 (T
0
, T
1
and T
2
).
• Check the engine oil level.
• Check the engine coolant level.
