｠

Not continuity.

Q:Is the harness connector in good condition?

YES:

Then go to Step 7.

NO:

Repair it. Then go to Step 8.

STEP 7. Replace the fuel tank differential pressure sensor.

(1)

Replace the fuel tank differential pressure sensor.

(2)

Carry out test drive with the drive cycle pattern. Refer to
Diagnostic Function. OBD-II Drive Cycle. Pattern 24 P.
13Ab-8.

(3)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0452 set?

YES:

Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 8.

NO:

The inspection is complete.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0452 set?

YES:

Repeat the troubleshooting.

NO:

The procedure is complete.

CIRCUIT OPERATION

｠

The ECM (terminal No. 114) supplies a 5-volt
reference voltage to the fuel tank differential
pressure sensor (terminal No. 3). The ECM
(terminal No. 113) supplies a ground to the fuel tank
differential pressure sensor (terminal No. 2).

｠

The ECM (terminal No. 112) receives a voltage
signal proportional to the pressure in the fuel tank
from the fuel tank differential pressure sensor
(terminal No. 1).

TECHNICAL DESCRIPTION

｠

To determine whether the fuel tank differential
pressure sensor is defective, the ECM monitors the
fuel tank differential pressure sensor output voltage.

｠

The ECM judges if the fuel tank differential pressure
sensor output voltage is normal.

NOTE:

In rare cases, this DTC may be also set

under some fuel and driving conditions regardless
of the fuel pressure sensor output voltage when
the fuel system is clogged.

DESCRIPTIONS OF MONITOR METHODS

｠

Compare purge solenoid status with fuel tank
differential pressure sensor output voltage.

MONITOR EXECUTION

｠

Continuous.
