DTC |
P00CF62 |
Barometric Pressure - Turbocharger / Supercharger Boost Sensor "A" Signal Compare Failure |
DESCRIPTION
The No. 2 turbo pressure sensor is installed to the intercooler assembly and detects the turbo pressure.
When the ignition switch to ON or the engine is idling, the pressure detected by the No. 2 turbo pressure sensor and the atmospheric pressure sensor built into the ECM will both be the same as atmospheric pressure.

P00CF62 |
Barometric Pressure - Turbocharger / Supercharger Boost Sensor "A" Signal Compare Failure |
Difference between atmospheric pressure value of the No. 2 turbo pressure sensor and atmospheric pressure sensor is higher than threshold value (1 trip detection logic). |
|
Comes on |
SAE Code: P00CF |
MONITOR DESCRIPTION
When the ignition switch to ON or the engine is idling, the pressures detected by the the No. 2 turbo pressure sensor and the atmospheric pressure sensor (built into ECM) are compared. If the difference in the pressures detected is higher than threshold value, the ECM determines that the No. 2 turbo pressure sensor or atmospheric pressure sensor may be malfunctioning. In this case, the ECM illuminates the MIL and stores this DTC.

CONFIRMATION DRIVING PATTERN
HINT:
-
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

![2023 - 2025 MY GR Corolla [09/2022 - ]; G16E-GTS (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR](/t3Portal/stylegraphics/info.gif)
-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- 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.
- Start the engine and wait 5 seconds or more [A].
- Enter the following menus: Powertrain / Engine / Trouble Codes [B].
-
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: P00CF62.
-
Check the DTC judgment result.

ABNORMAL
- DTC judgment completed
- System abnormal
INCOMPLETE
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result is INCOMPLETE, perform steps [A] through [B] again.
-
[A] to [C]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

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.

- 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 and Boost Pressure Sensor or Boost Pressure Sensor2 values in the Data List with the normal atmospheric value from the table.
