DTC P0453 EVAP CONTROL SYSTEM PRESSURE SENSOR
Component Description
INFOID:0000000001326212
The EVAP control system pressure sensor detects pressure in the purge line. The sensor output voltage to the
ECM increases as pressure increases.
CONSULT-III Reference Value in Data Monitor Mode
INFOID:0000000001326213
Specification data are reference values.
On Board Diagnosis Logic
INFOID:0000000001326214
NOTE:
If DTC P0453 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.
Refer to

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.
