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 17.

NG

>> Replace EVAP control system pressure sensor.
