PROCEDURE
INSPECT VACUUM SENSOR (MANIFOLD ABSOLUTE PRESSURE SENSOR)
Check the terminal voltage.
Disconnect the vacuum sensor (manifold absolute pressure sensor) connector.
Turn the engine switch on (IG).

Measure the voltage according to the value(s) in the table below.
| Standard Voltage | ||||||||
|---|---|---|---|---|---|---|---|---|

If the result is not as specified, repair or replace the wire harness or connector.
Check the intake manifold pressure.
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Engine and ECT / Data List / MAP.
According to the display on the GTS read the Data List.
| OK |

| The value is approximately equal to atmospheric pressure. |
Tech Tips
Standard atmospheric pressure is 101 kPa (abs) (758 mmHg (abs)).
For every 100 m (328 ft.) increase in altitude, pressure drops by 1 kPa (7.5 mmHg). This varies with the weather.
