DTC P0069-273: Manifold Absolute Pressure - Barometric Pressure Correlation [10/2015 - ]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the power switch 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 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.

6. Turn the power switch off.

A 

See step  3

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
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 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

6. Turn the power switch off.

A 

See step  4

1. Connect the Techstream to the DLC3.
2. Turn the power switch on (IG).
3. Move the shift lever to P.
4. Enter the following menus: Powertrain / Hybrid Control / Data List / MAP
5. Read the "MAP" value in the Data List with the engine stopped.
6. While depressing the brake pedal, turn the power switch on (READY).
7. With the READY indicator light illuminated, fully depress the accelerator pedal.
8. Read the "MAP" value in the Data List with the engine running.
9. 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).
