HYBRID CONTROL SYSTEM, Diagnostic DTC:P0069-273

DTC Code DTC Name
P0069-273 Manifold Absolute Pressure - Barometric Pressure Correlation

DESCRIPTION

The atmospheric pressure sensor mounted on the MG ECU circuit board detects the atmospheric pressure. This reading is used to perform system control that determines vehicle usage conditions.

A01SFLWE01
DTC No. Detection Item DTC Detection Condition Trouble Area MIL Warning Indicate
P0069-273 Manifold Absolute Pressure - Barometric Pressure Correlation Difference between the atmospheric pressure value of the atmospheric pressure sensor in the inverter with converter assembly and the manifold absolute pressure sensor (for EGR control) exceeds a specified value. The same condition recurs within 3 hours when driving in EV drive mode.

PROCEDURE


  1. CHECK DTC OUTPUT (ENGINE AND ECT)


    1. Connect the GTS 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.


      Powertrain > Engine and ECT > Trouble Codes

      Powertrain > Hybrid Control > Data List
      Tester Display
      MAP
      Atmosphere Pressure

    4. Using the table, read the normal atmospheric pressure value for the applicable altitude.

      A01SF7Q

    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.
