TROUBLE DIAGNOSIS
Revision: 2006 November2007 350Z
INT/V SOL(B1) [%]
The control value of the intake valve timing control
solenoid valve (determined by ECM according to the
input signals) is indicated.

The advance angle becomes larger as the value
increases. INT/V SOL(B2) [%]
EX VTC DTY B1 [%]

The control value of the exhaust valve timing control
magnet retarder (determined by ECM according to the
input signals) is indicated.

The retard angle becomes larger as the value
increases. EX VTC DTY B2 [%]
TP SEN 1-B2 [V]

The throttle position sensor signal voltage is dis-
played.
THRTL SEN 2-B2 signal is converted by ECM
internally. Thus, it differs from ECM terminal
voltage signal. TP SEN 2-B2 [V]
AIR COND RLY [ON/
OFF]

The air conditioner relay control condition (determined
by ECM according to the input signals) is indicated.
FUEL PUMP RLY [ON/
OFF]

Indicates the fuel pump relay control condition deter-
mined by ECM according to the input signals.
VENT CONT/V [ON/
OFF]

The control condition of the EVAP canister vent control
valve (determined by ECM according to the input sig-
nals) is indicated.
ON: Closed
OFF: Open
THRTL RELAY [ON/
OFF]

Indicates the throttle control motor relay control condi-
tion determined by the ECM according to the input sig-
nals.
COOLING FAN
[HI/LOW/OFF]

The control condition of the cooling fan (determined by
ECM according to the input signals) is indicated.
HI: High speed operation
LOW: Low speed operation
OFF: Stop
HO2S2 HTR (B1) [ON/
OFF]

Indicates [ON/OFF] condition of heated oxygen sensor
2 heater determined by ECM according to the input
signals. HO2S2 HTR (B2) [ON/
OFF]
I/P PULLY SPD

Indicates the engine speed computed from the turbine
revolution sensor signal.
VEHICLE SPEED
[km/h] or [mph]

Indicates the vehicle speed computed from the revolu-
tion sensor signal.
IDL A/V LEARN [YET/
CMPLT]

Display the condition of Idle Air Volume Learning
YET: Idle Air Volume Learning has not been performed
yet.
CMPLT: Idle Air Volume Learning has already been
performed successfully.
TRVL AFTER MIL [km]
or [mile]

Distance traveled while MIL is activated.
ENG OIL TEMP [°C] or
[°F]

The engine oil temperature (determined by the signal
voltage of the engine oil temperature sensor) is dis-
played.
A/F S1 HTR(B1) [%]

Indicates A/F sensor 1 heater control value computed
by ECM according to the input signals.

The current flow to the heater becomes larger as the
value increases. A/F S1 HTR(B2) [%]
AC PRESS SEN [V]

The signal voltage from the refrigerant pressure sen-
sor is displayed. Monitored item [Unit] Description Remarks
