If you do not know the atmospheric pressure refer to the Vapor Pressure Pump value of other vehicles in the workshop and check the difference in pressure. RESULT Result Proceed to If the Vapor Pressure Pump value differs from the atmospheric pressure by +/- 3.5 kPa (+/- 26.25 mmHg) or more A If the MAP value differs from the atmospheric pressure by +/- 3.5 kPa (+/- 26.25 mmHg) or more B B --> See step 4 A: Go to next step
3. REPLACE CANISTER Replace the canister. Refer to «REMOVAL»(ref-393178-S22090145052011040700000) . NEXT --> See step 5
4. REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR Replace the manifold absolute pressure sensor. Refer to «REMOVAL»(ref-393178-S01480003242011040700000) . NEXT: Go to next step
5. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED Connect the Techstream to the DLC3. Turn the power switch on (IG) and the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Data List / MAP and Vapor Pressure Pump. Confirm that the difference between Vapor Pressure Pump and MAP are 3.5 kPa (+/- 26.25 mmHg) or less. NEXT --> END
6. GO TO DTC CHART. Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-393183-S20320380732011040700000)
