SELF-DIAGNOSTIC FUNCTION AND DIAGNOSTIC CODE TABLE
DTC Item
P0106 Intake air pressure
sensor 1: clogging
of hose or sensor in-
stallation improper-
ly. Stable pressure
is not supplied.
P0107 [P0107] Intake air
P0108 pressure sensor 1:
short to ground cir-
cuit is detected.
Normal signal is not
received from the in-
take air pressure
sensor 1 circuit.
[P0108] Intake air
pressure sensor 1:
open or short to
power circuit is de-
tected. Normal sig-
nal is not received
from the intake air
pressure sensor 1
circuit.
Probable cause of
malfunction
• Intake air pressure
sensor 1 hose is
not installed.
• Intake air pressure
sensor 1 hose is
not installed cor-
rectly (Detached,
clogged, twisted or
pinching).
• Intake air pressure
sensor 1 hole is
clogged, or intake
air pressure sen-
sor 1 is not in-
stalled correctly.
[P0107] Low voltage
of the intake air
pressure sensor 1
circuit (0.5 V or less)
[P0108] High volt-
age of the intake air
pressure sensor 1
circuit (4.8 V or
more)
• Defective coupler
between intake air
pressure sensor 1
and ECU.
• Open or short cir-
cuit in wire har-
ness between
intake air pressure
sensor 1 and ECU.
• Poor circuit conti-
nuity in wire har-
ness between
intake air pressure
sensor 1 and ECU.
• Defective intake
air pressure sen-
sor 1.
• Malfunction in
ECU.
