P006D62 |
Barometric Pressure - Turbocharger/Supercharger Inlet Pressure Correlation Bank 1 Signal Compare Failure |
DESCRIPTION
The manifold absolute pressure sensor is installed upstream of the turbocharger compressor and measures the air inlet duct internal pressure with a built-in sensor.
At ignition switch to ON or during idling, the manifold absolute pressure sensor and the atmospheric pressure sensor built into the ECM are at atmospheric pressure and their output match.

SAE Code: P006D |
MONITOR DESCRIPTION
At ignition switch to ON or during idling, if the difference in atmospheric pressure values is the threshold or greater when the output values from the manifold absolute pressure sensor and the atmospheric pressure sensor built into the ECM are compared, or if the deviation between the air cleaner pressure loss calculated from the atmospheric pressure and manifold absolute pressure sensor and the air cleaner pressure loss estimated from the mass air flow meter sub-assembly is at the threshold or higher while driving (example: when the intake air volume is 40 gm/sec, the value obtained by subtracting the atmospheric pressure from the manifold absolute pressure sensor value is larger than 7.5 kPa [1.09 psi]or less than -9.2 kPa [-1.33 psi]), the ECM stores a DTC.
CONFIRMATION DRIVING PATTERN
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON and turn the GTS on [A].
- Start the engine and wait 5 seconds or more [B].
- Drive the vehicle at 40 km/h (25 mph) for 5 seconds or more [C].
- Enter the following menus: Powertrain / Engine / Trouble Codes [D].
-
Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P006D62.
-
Check the DTC judgment result.

CAUTION / NOTICE / HINT
HINT:
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
|
1. |
CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P006D62) |
(a) Read the DTCs.
Powertrain > Engine > Trouble Codes
|
Result |
Proceed to |
|---|---|
|
P006D62 is output |
A |
|
P006D62 and other DTCs are output |
B |
HINT:
If any DTCs other than P006D62 are output, troubleshoot those DTCs first.

|
Atmospheric Pressure |
|
Turbocharger/Supercharger Inlet Pressure Bank1 |
(b) Compare Turbocharger/Supercharger Inlet Pressure Bank1 and Atmospheric Pressure in the Data List.
|
Result |
Proceed to |
|---|---|
|
Difference between Turbocharger/Supercharger Inlet Pressure Bank1 and Atmospheric Pressure in the Data List exceeds 7.1 kPa [1.03 psi] |

READ VALUE USING GTS (ATMOSPHERIC PRESSURE) |
(a) Enter the following menus.
Powertrain > Engine > Data List
|
Tester Display |
|---|
|
Atmospheric Pressure |
(b) Using the table, read the normal atmospheric pressure value for the applicable altitude and temperature.
HINT:
- Standard atmospheric pressure is approximately 101 kPa(abs) [14.65 psi(abs)].
- For every 100 m (328 ft.) increase in altitude, atmospheric pressure drops by approximately 1 kPa [0.15 psi]. This varies by weather.
(c) Compare the Atmospheric pressure value in the Data List with the normal atmospheric value from the table.
|
Result |
Proceed to |
|---|---|
|
Other than the following |
A |
|
Difference between Atmospheric Pressure in the Data List and normal atmospheric pressure value is 10 kPa (1.45 psi) or more. |
