DTC P0107: Manifold Absolute Pressure / Barometric Pressure Circuit Low Input; DTC P0108: Manifold Absolute Pressure / Barometric Pressure Circuit High Input [03/2019 - 11/2022]: Procedure
WARNING: This page is about a different car, the 2022 Toyota Corolla, 2021 Toyota Corolla, 2020 Toyota Corolla, and 2019 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK TERMINAL VOLTAGE (POWER SOURCE OF MANIFOLD ABSOLUTE PRESSURE SENSOR)
*a Front view of wire harness connector
(to Manifold Absolute Pressure Sensor)HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
- Disconnect the manifold absolute pressure sensor connector.
- Turn the ignition switch to ON.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition C115-3 (VC) - C115-1 (E2) Ignition switch ON 4.75 to 5.25 V C115-2 (PIM) - C115-1 (E2) Ignition switch ON 3.0 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 C115-3 (VC) - C115-2 (PIM) Ignition switch off 171 to 189 kΩ C115-1 (E2) - Body ground Always Below 1 Ω Result
Proceed to OK NG
Result:
OK
REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR
Refer to REMOVAL [01/2019 - 11/2022]
Result:
NG
See step 2
- CHECK HARNESS AND CONNECTOR (MANIFOLD ABSOLUTE PRESSURE SENSOR - ECM)
- Disconnect the manifold absolute 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 C115-3 (VC) - C77-77 (VCPM) Always Below 1 Ω C115-1 (E2) - C77-76 (EPIM) Always Below 1 Ω C115-2 (PIM) - C77-78 (PIM) Always Below 1 Ω C115-2 (PIM) or C77-78 (PIM) - Body ground and other terminals Always 10 kΩ or higher Result
Proceed to OK NG
Result:
OK
REPLACE ECM
Refer to REMOVAL [03/2019 - 09/2022] , or refer to REMOVAL [09/2022 - 11/2022]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
