DTC P0453 EVAP CONTROL SYSTEM PRESSURE SENSOR

Specification data are reference values and are measured between each terminal and ground.

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Diagnostic Procedure

UBS00D83

1. 

CHECK RUBBER TUBE CONNECTED TO THE SENSOR

Check rubber tube connected to the sensor for clogging, vent, kink, disconnection or improper connection.

OK or NG

OK

>> GO TO 2.

NG

>> Reconnect, repair or replace.

2. 

RETIGHTEN GROUND SCREWS

1.

Turn ignition switch OFF.

2.

Loosen and retighten engine ground screws.

>> GO TO 3.

3. 

CHECK HARNESS CONNECTOR

1.

Disconnect EVAP control system pressure sensor harness con-
nector.

2.

Check sensor harness connector for water.
Water should not exist.

OK or NG

OK

>> GO TO 4.

NG

>> Repair or replace harness connector.

4. 

CHECK POWER SUPPLY

1.

Turn ignition switch ON.

2.

Check voltage between EVAP control system pressure sensor
terminal 3 and engine ground with CONSULT-II or tester.

OK or NG

OK

>> GO TO 6.

NG

>> GO TO 5.

5. 

DETECT MALFUNCTIONING PART

Check the following.

●

Harness connectors C1, M67

●

Harness connectors M59, F27

●

Harness for open or short between EVAP control system pressure sensor and ECM

>> Repair harness or connectors.

6. 

CHECK GROUND CIRCUIT

1.

Turn ignition switch OFF.

2.

Check harness continuity between EVAP control system pressure sensor terminal 1 and engine ground.
Refer to Wiring Diagram.

3.

Also check harness for short to power.

OK or NG

OK

>> GO TO 8.

NG

>> GO TO 7.

7. 

DETECT MALFUNCTIONING PART

Check the following.

●

Harness connectors C1, M67

●

Harness connectors M81, F36

●

Harness for open or short between EVAP control system pressure sensor and ECM

>> Repair open circuit or short to power in harness or connectors.

Voltage

: Approximately 5V

SEF410Q

Continuity should exist.

8. 

CHECK INPUT SIGNAL CIRCUIT

1.

Disconnect ECM harness connector.

2.

Check harness continuity between ECM terminal 62 and EVAP control system pressure sensor terminal
2.
Refer to Wiring Diagram.

3.

Also check harness for short to ground and short to power.

OK or NG

OK (With CONSULT-II)>>GO TO 10.
OK (Without CONSULT-II)>>GO TO 11.
NG

>> GO TO 9.

9. 

DETECT MALFUNCTIONING PART

Check the following.

●

Harness connectors C1, M67

●

Harness connectors M59, F27

●

Harness for open or short between EVAP control system pressure sensor and ECM

>> Repair open circuit or short to ground or short to power in harness or connectors.

10. 

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

 With CONSULT-II

1.

Start engine.

2.

Perform  “PURG VOL CONT/V” in “ACTIVE TEST” mode with
CONSULT-II. Check that engine speed varies according to the
valve opening.

OK or NG

OK

>> GO TO 12.

NG

>> GO TO 11.

Continuity should exist.
