DTC P0069-273: Manifold Absolute Pressure - Barometric Pressure Correlation: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON (READY).
3. Fully depress the accelerator pedal for 5 seconds to start the engine and keep it running.
4. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
5. Check if DTCs are output.

   Result

   Result	Proceed to
   DTCs other than 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 output due to a malfunction which causes the DTCs in the table above to be output. In this case, first troubleshoot the output DTCs in the table above. Then, perform a reproduction test to check that no DTCs are output.

6. Turn the ignition switch off.

   HINT: 

   • *1: If any INF codes are output for this DTC, refer to the corresponding diagnostic procedure.
   • P0069-273 may be output due to a malfunction which causes the DTCs in the table above to be output. In this case, first troubleshoot the output DTCs in the table above. Then, perform a reproduction test to check that no DTCs are output.
5. Turn the ignition switch off.

B → See step   11 

A: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Enter the following menus: Powertrain / Hybrid Control / Data List / MAP, Atmosphere Pressure.
4. Using the table, read the normal atmospheric pressure value for the applicable altitude.

5. Compare the MAP and Atmosphere Pressure values in the Data List with the normal atmospheric pressure value from the table.

   Result

   Result	Proceed to
   Other than 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

6. Turn the ignition switch off.

B → See step   5 

C → See step   10 

A: Go to next step 

1. Move the shift lever to P.
2. Enter the following menus: Powertrain / Hybrid Control / Data List / MAP.
3. Read the MAP value in the Data List with the engine stopped.
4. While depressing the brake pedal, turn the ignition switch to ON (READY).
5. With the READY indicator light illuminated, fully depress the accelerator pedal.
6. Read the MAP value in the Data List with the engine running.
7. 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).

8. Turn the ignition switch off.
