Toyota Yaris: Manifold Absolute Pressure Sensor / On-vehicle Inspection
ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT NO. 1 TURBO PRESSURE SENSOR
(a) Check the terminal voltage.
(1) Disconnect the No. 1 turbo pressure sensor connector.
(2) Turn the ignition switch to ON.
| (3) 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. |
|
(b) Check the turbo pressure.
(1) Connect the GTS to the DLC3.
(2) Turn the ignition switch to ON.
(3) Turn the GTS on.
(4) Enter the following menus: Powertrain / Engine / Data List / Boost Pressure Sensor.
Powertrain > Engine > Data List| Tester Display |
|---|
| Boost Pressure Sensor |
(5) According to the display on the GTS read the Data List.
OK:
The value is approximately equal to atmospheric pressure.
HINT:
- 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.
