CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
1.
Remove EVAP control system pressure sensor with its harness
connector connected.
2.
Remove hose from EVAP control system pressure sensor.
3.
Use pump to apply vacuum and pressure to EVAP control system pressure sensor as shown in figure.
CAUTION:
●
Always calibrate the vacuum pump gauge when using it.
●
Do not apply below
−93.3 kPa (−700 mmHg, −27.56 inHg) or over 101.3 kPa (760 mmHg, 29.56
inHg) of pressure.
4.
Check output voltage between ECM terminal 62 and engine
ground.
CAUTION:
Discard any EVAP control system pressure sensor which
has been dropped from a height of more than 0.5 m (19.7 in)
onto a hard surface such as a concrete floor; use a new
one.
OK or NG
OK
>> GO TO 18.
NG
>> Replace EVAP control system pressure sensor.

On Board Diagnosis Logic
UBS00D87
This diagnosis detects very small leaks in the EVAP line between the fuel tank and the EVAP canister purge
volume control solenoid valve using intake manifold vacuum in the same way as conventional EVAP small
leak diagnosis.
If the ECM judges a leak equivalent to a very small leak, the very small leak DTC P0456 or P1456 will be
detected. If the ECM judges a leak equivalent to a small leak, the EVAP small leak DTC P0442 will be
detected. Correspondingly, if the ECM judges there is no leak, the diagnosis result is OK.
