DTC P0069-273: Manifold Absolute Pressure - Barometric Pressure Correlation [08/2013 - ]: Procedure
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK DTC OUTPUT (ENGINE AND ECT)
- Connect the Techstream to the DLC3.
- Turn the power switch on (READY).
- Fully depress the accelerator pedal for 5 seconds to start the engine and keep it running.
- Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
- Check for DTCs.
Result
Result Proceed to DTCs except those listed in the following table are output. A Any of the following DTCs are also output. B DTC No. Relevant Diagnosis P0107 Manifold Absolute Pressure / Barometric Pressure Circuit Low Input P0108 Manifold Absolute Pressure / Barometric Pressure Circuit High Input P106A Evaporative Emission System Pressure Sensor - Manifold Absolute Pressure Correlation HINT:
P0069-273 may be stored due to a malfunction which causes the DTCs in the preceding table to be stored. In this case, first troubleshoot the output DTCs in the preceding table. Then, perform a reproduction test to check that no DTCs are output.
- Turn the power switch off.
B → See step 10
A: Go to next step
- CHECK DTC OUTPUT (HYBRID CONTROL)
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
- Check for DTCs.
Result
Result Proceed to P0069-273 only is output, or DTCs except the ones in the table below are also output. A Any of the following DTCs are also output. B DTC No. Relevant Diagnosis P0A1A-151, 155, 156, 658, 659 Generator Control Module P0A1B-193, 512, 661, 786 Drive Motor "A" Control Module P0A1D-148 Hybrid Powertrain Control Module P2228-268 Barometric Pressure Sensor "A" Circuit Low P2229-269 Barometric Pressure Sensor "A" Circuit High P2511-149 ECM/PCM Power Relay Sensor Circuit Intermittent P324E-788 MG-ECU Power Relay Intermittent Circuit U0100-211, 530 Lost Communication with ECM/PCM "A" U0110 (all INF codes)*1 Lost Communication with Drive Motor Control Module "A" HINT:
- *1: If any INF codes are output for this DTC, refer to the corresponding diagnostic procedure.
- P0069-273 may be stored due to a malfunction which causes the DTCs in the preceding table to be stored. In this case, first troubleshoot the output DTCs in the preceding table. Then, perform a reproduction test to check that no DTCs are output.
- Turn the power switch off.
B → See step 12
A: Go to next step
- READ VALUE USING TECHSTREAM (MAP, ATMOSPHERE PRESSURE)
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Enter the following menus: Powertrain / Hybrid Control / Data List / MAP, Atmosphere Pressure.
- Using the table, read the normal atmospheric pressure value for the applicable altitude.
- Compare the MAP and Atmosphere Pressure values in the Data List with the normal atmospheric value from the table.
Result
Result Proceed to Except the following. A Difference between "MAP" in Data List and normal atmospheric pressure value is 10 kPa or more. B Difference between "Atmosphere Pressure" in Data List and normal atmospheric pressure value is 10 kPa or more. C - Turn the power switch off.
B → See step 5
C → See step 11
A: Go to next step
- READ VALUE USING TECHSTREAM (MAP)
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Move the shift lever to P.
- Enter the following menus: Powertrain / Hybrid Control / Data List / MAP
- Read the "MAP" value in the Data List with the engine stopped.
- While depressing the brake pedal, turn the power switch on (READY).
- With the READY indicator light illuminated, fully depress the accelerator pedal.
- Read the "MAP" value in the Data List with the engine running.
- Compare the "MAP" value noted with the engine stopped and the "MAP" value noted with the engine running.
OK
The "MAP" value changes (pressure decreases when the engine is started).
- Turn the power switch off.
NG → See step 5
OK → See step 11
- CHECK TERMINAL VOLTAGE (POWER SOURCE OF MANIFOLD ABSOLUTE PRESSURE SENSOR). Refer to PROCEDURE - Step 2
NG → See step 9
OK: Go to next step
- REPLACE MANIFOLD ABSOLUTE PRESSURE SENSOR
Refer to COMPONENTS [08/2013 - ]
NEXT: Go to next step
- CLEAR DTC
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
- Read and record the DTCs and freeze frame data.
- Clear the DTCs and freeze frame data.
- Turn the power switch off.
NEXT: Go to next step
- CHECK DTC OUTPUT (HYBRID CONTROL)
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
- Check for DTCs.
Result
Result Proceed to P0069-273 is not output. A P0069-273 is output again. B - Turn the power switch off.
B → See step 13
A → COMPLETED
- CHECK HARNESS AND CONNECTOR (MANIFOLD ABSOLUTE PRESSURE SENSOR - ECM). Refer to PROCEDURE - Step 5
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 13
- GO TO DTC CHART (SFI SYSTEM). Refer to DIAGNOSTIC TROUBLE CODE CHART [08/2013 - ]
- REPLACE INVERTER WITH CONVERTER ASSEMBLY. Refer to COMPONENTS [08/2013 - ]
- GO TO DTC CHART (HYBRID CONTROL SYSTEM). Refer to DIAGNOSTIC TROUBLE CODE CHART [08/2013 - ]
- REPLACE ECM. Refer to COMPONENTS [08/2013 - ]
