Title: G16E-GTS (ENGINE CONTROL): MANIFOLD ABSOLUTE PRESSURE SENSOR: ON-VEHICLE INSPECTION; 2023 - 2025 MY GR Corolla [09/2022 -        ]

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 engine switch on (IG).

(3) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

Tester Connection

Condition

Specified Condition

C136-3(VC) - C136-2(E2)

Engine switch on (IG)

4.75 to 5.25 V

C136-1(PIM) - C136-2(E2)

1.2 to 5.25 V

If the result is not as specified, repair or replace the wire harness or connector.

2. INSPECT NO. 2 TURBO PRESSURE SENSOR

(a) Check the terminal voltage.

(1) Disconnect the No. 2 turbo pressure sensor connector.

(2) Turn the engine switch on (IG).

(3) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

Tester Connection

Condition

Specified Condition

C135-3(VC) - C135-2(E2)

Engine switch on (IG)

4.5 to 5.5 V

C135-1(PTA) - C135-2(E2)

3.0 to 5.5 V

If the result is not as specified, repair or replace the wire harness or connector.

(b) Check the turbo pressure.

(1) Connect the Techstream to the DLC3.

(2) Turn the engine switch on (IG).

(3) Turn the Techstream 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 Techstream read the Data List.

OK:

The value is approximately equal to atmospheric pressure.

HINT:

  • Standard atmospheric pressure is approximately 101 kPa (abs) (15 psi (abs)).
  • For every 100 m (328 ft) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.15 psi). This varies by weather.
