DTC P0069-00: Manifold Absolute Pressure - Barometric Pressure Correlation [03/2022 - 03/2023]: Procedure
WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0069-00)
- Read the DTCs.
Powertrain > Engine > Trouble Codes
Result
Result Proceed to DTC P0069-00 is output A DTC P0069-00 and other DTCs are output B HINT:
If any DTCs other than P0069-00 are output, troubleshoot those DTCs first.
Result:
B
GO TO DTC CHART. Refer to DIAGNOSTIC TROUBLE CODE CHART [03/2022 - 03/2023] , or Refer to
Result:
A
See step 2
- Read the DTCs.
- READ VALUE USING GTS (INTAKE MANIFOLD ABSOLUTE PRESSURE)
- Turn the ignition switch off and wait for at least 50 minutes.
- Using the following table, determine the normal atmospheric pressure for the current altitude and temperature.
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 (0.1 psi). This varies depending on the weather.
- Compare the value of the Data List item Intake Manifold Absolute Pressure with the actual atmospheric pressure.
Powertrain > Engine > Data List
Tester Display Intake Manifold Absolute Pressure Result
Result Proceed to Approximately the same as the actual atmospheric pressure A Not approximately the same as the actual atmospheric pressure B
Result:
B
REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR. Refer to REMOVAL [11/2021 - ]
Result:
A
See step 3
- READ VALUE USING GTS (ATMOSPHERIC PRESSURE)
- Using the following table, determine the normal atmospheric pressure for the current altitude and temperature.
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 (0.1 psi). This varies depending on the weather.
- Compare the value of the Data List item Atmospheric Pressure with the actual atmospheric pressure.
Powertrain > Engine > Data List
Tester Display Atmospheric Pressure Result
Result Proceed to Approximately the same as the actual atmospheric pressure A Not approximately the same as the actual atmospheric pressure B
Result:
A
CHECK FOR INTERMITTENT PROBLEMS. Refer to CHECK FOR INTERMITTENT PROBLEMS [11/2021 - ]
Result:
B
REPLACE ECM. Refer to REMOVAL [11/2021 - ]
- Using the following table, determine the normal atmospheric pressure for the current altitude and temperature.
