Emission Control System
Check the vacuum when hot:1. Turn the ignition switch OFF.2. Block the rear wheels and setthe parking brake.3. Jack up the front of the vehi-cle and support it with safetystands.4- Start the engine. Hold theengine at 3,000 rpm with noload (in Park or neutral) untilthe radiator fan comes on, thenlet it idle.5. Check for vacuum at the vacuum hose with transmissionin gear (A/T in E position,M/T in 'l st gear) after startingrne engrne.6. Ouickly raise the engine speedto 3,000 rpm.

Remove the fuelfill cap.
Remove the vapor line from the EVAP two way
valve, and connect it ro a T-fitting from a vacuum
gauge ano a vacuum pump as shown.

3. Apply vacuum slowly and continuously while watch-
ing the gauge. The vacuum should stabilize momen-
tarily at 0.8 - 2.1 kPa (6 - 16 mmHg, 0.2 - 0.6 in.Hg).
lf the vacuum stabilizes {valve opens) below
0.8 kPa (6 mmHg,0.2 in.Hg) or above 2.1 kPa(16'mmHg,0.6 in.Hg), install a new valve and retest.
4. Move the vacuum oumo hose from the vacuum fit-
ting to the pressure fining, and move the vacuum
gauge hose from the vacuum side to the pressure
side as shown.
PRESSUREstoE
Slowly pressurize the vapor line while watching thegauge. The pressure should be stabilize momentarily
above 1.0 kPa (8 mmHg, 0.3 in.Hg).
lf the pressure momentarily stabilizes (valve
opens) above'1.0 kPa (8 mmHg.0.3 in.Hg), the
valve is OK.
lf the pressure stabilizes below 1.0 kPa {8 mmHg,
0.3 in.Hg), install a new valve and retest.
