DTC set condition
(1)
DTC detection condition
The conditions described below remain for 11 seconds or more.
•
The battery voltage is in the range of 10 to 16 V.
•
The condition that the engine speed remains at 500 r/min or more for 5 seconds or more.
The conditions described below remain for 40 seconds or more.
•
The battery voltage is in the range of 10 to 16 V.
•
The engine is stopped, or the engine speed remains at 500 r/min or more for 5 seconds or more.
•
The engine speed is 1000 r/min or less.
•
Fuel injection quantity is 35 mm
3
/st.cyl or less.
•
Engine coolant temperature is in the range of -30 to 60
C {-22 to 140
F}.
•
The battery voltage is in the range of 10 to 16 V.
•
The engine is stopped, or the engine speed remains at 500 r/min or more for 5 seconds or more.
(2)
Judgement criteria
•
Judged when the calculated EGR cooler efficiency is greater than 65%,
•
the difference between the calculated intake manifold air intake temperature and the actual intake air is higher
than 60
C {140
F} or less than -60
C {-76
F}, and
•
the calculated intercooler efficiency is higher than the specified value (30% or more when the vehicle speed is
13 mile/h, 50% or more when the vehicle speed is 25 mile/h).
3.
Reset condition
•
After restoration to normal condition
4.
Indication, warning or system control regulation when the DTC is set.
•
MIL: ON
•
SVS light: OFF
5.
Symptoms on the vehicle when the DTC is set
<Symptoms on the vehicle due to backup control (fail safe function)>
•
–
<Symptoms on the vehicle due to malfunction>
•
–
6.
Pre-inspection work
•
Check that the battery voltage is in the normal range.
7.
After-inspection work
•
Clear all past DTCs.
•
Check that no DTC is stored after test drive.
8.
Estimated failure factors
•
Failure of intercooler outlet temperature sensor
•
Failure of intake air temperature sensor (with built-in air flow sensor)
•
Failure of intake manifold temperature sensor
•
Failure of boost pressure sensor
- Sensor is disconnected from measuring site or sensing unit is malfunctioning (due to dirt, clogging, damage, etc.)
- Faulty resistance (due to sticking)
•
Malfunction of ECU sensor power supply
