ENGINE (J05E)/TROUBLESHOOTING
2–215
DTC: P0106
EN01H02127030602016041
P0106: Boost pressure sensor - rationality
INFORMATION
1.
Technical description
•
The boost pressure sensor mounted on the diesel throttle outlet constantly measures the boost pressure.
<Description of malfunction>
•
Boost pressure cannot be correctly recognized.
2.
DTC set condition
(1)
DTC detection condition
•
Engine speed is between 720 r/min and 980 r/min.
•
Engine speed variation is 234.4 r/min/sec or less.
•
Fuel injection rate is between 0 mm
3
/st. cyl and 80 mm
3
/st. cyl.
•
Fuel injection rate variation is 78.1 mm
3
/st. cyl or less.
•
Engine coolant temperature is 55
C {131
F} or less.
•
EGR valve opening is 0% or less (EGR-cut status)
•
Exhaust brake is not actuated
(2)
Judgement criteria
•
Theoretical air quantity calculated from boost pressure and atmospheric pressure and actual air quantity are
compared for at least 10 seconds, and the ratio of theoretical air quantity to actual air quantity is at least 1.15
or no greater than 0.75.
•
And: Difference between DCY value prior to above result and current DCY value is 0.10 or less; and
•
When prior DCY starter key is turned "LOCK" and engine is stopped, (Average boost pressure
–
average
atmospheric pressure) is
≥
18 kPa, and this condition continues for at least 3 seconds.
3.
Reset condition
•
After restoration to normal condition and starter key "LOCK".
4.
Indication, warning or system control regulation when the DTC is set.
•
MIL: ON
•
SVS light: OFF
•
Engine output is restricted.
