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: Tester Connection | Condition | Specified Condition | D95-3(VC) - D95-2(E2) | Ignition switch ON | 4.75 to 5.25 V | D95-1(PIM) - D95-2(E2) | 3.0 to 5.25 V | 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

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.
REMOVAL PROCEDURE 1. DISCONNECT ENGINE WIRE (a) Remove the bolt.
(b) Disengage the clamp and disconnect the engine wire. 2. REMOVE NO. 1 TURBO PRESSURE SENSOR (a) Disconnect the No...
