DTC P0105-15: Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Battery or Open [10/2022 - ]: Procedure
WARNING: This page is about a different car, the 2025 Toyota Highlander, 2024 Toyota Highlander, and 2023 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK HARNESS AND CONNECTOR
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
- Disconnect the No. 1 turbo pressure sensor connector.
- Turn the ignition switch to ON.
- Measure the voltage according to the value(s) in the table below.

(to No. 1 Turbo Pressure Sensor)Standard Voltage
Tester Connection Condition Specified Condition C77-3 (VC) - C77-2 (E2) Ignition switch ON 4.5 to 5.5 V C77-1 (PIM) - C77-2 (E2) Ignition switch ON 1.2 to 5.25 V - Turn the ignition switch off and wait for at least 30 seconds.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition C77-2 (E2) - Body ground Ignition switch off Below 1 Ω C77-3 (VC) - C77-1 (PIM) Ignition switch off 171 to 189 kΩ Result
Proceed to OK NG
Result:
OK
REPLACE NO. 1 TURBO PRESSURE SENSOR
Refer to PROCEDURE - Step 2
Result:
NG
See step 2
- CHECK HARNESS AND CONNECTOR (NO. 1 TURBO PRESSURE SENSOR - ECM)
- Disconnect the No. 1 turbo pressure sensor connector.
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition C77-2 (E2) - C88-84 (EPIM) Always Below 1 Ω C77-1 (PIM) - C88-83 (PIM) Always Below 1 Ω C77-1 (PIM) or C88-83 (PIM) - Other terminals Always 10 kΩ or higher Result
Proceed to OK NG
Result:
OK
REPLACE ECM
Refer to REMOVAL [10/2022 - 11/2023] , or refer to REMOVAL [11/2023 - ]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
