NR Series ENGINE CONTROL  SFI SYSTEM  P00CF62  Barometric Pressure - Turbocharger / Supercharger Boost Sensor "A" Signal Compare Failure  


DESCRIPTION

The No. 1 turbo pressure sensor is installed between the intercooler and throttle body with motor assembly and measures the internal pressure of the intercooler. When the ignition switch is ON or the engine is idling, the No. 1 turbo pressure sensor and the atmospheric pressure sensor build into the ECM detect atmospheric pressure and output same value.

MONITOR DESCRIPTION

When the ignition switch is turned to ON or the engine is idling, the pressures detected by the No. 1 turbo pressure sensor and the atmospheric pressure sensor built into the ECM are compared. If the difference in the pressures detected is 15 kPa (2.18 psi) or higher, the ECM determines that the No. 1 turbo pressure sensor or atmospheric pressure sensor may be malfunctioning. In this case, the ECM illuminates the MIL and stores this DTC.

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.

·

When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

Click hereEngine / Hybrid System>NR Series (ENGINE CONTROL)>SFI SYSTEM>DTC CHECK / CLEAR



1.

Connect the GTS to the DLC3.

2.

Turn the ignition switch to ON.

3.

Turn the GTS on.

4.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

5.

Turn the ignition switch off and wait for at least 30 seconds.

6.

Start the engine and wait 5 seconds or more [A].

7.

Turn the GTS on.

8.

Enter the following menus: Powertrain / Engine / Trouble Codes [B].

9.

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.



10.

Enter the following menus: Powertrain / Engine / Utility / All Readiness.

11.

Input the DTC: P00CF62.

12.

Check the DTC judgment result.

GTS Display Description

ABNORMAL
·

·

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.

·

[A] to [B]: 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.


PROCEDURE

1.CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P00CF62)
a.

Connect the GTS to the DLC3.


b.

Turn the ignition switch to ON.


c.

Turn the GTS on.


d.

Enter the following menus: Powertrain / Engine / Trouble Codes.

HINT:

If any DTCs other than P00CF62 and P023400, P023562, P211900, P211904 or P211977 are output, troubleshoot those DTCs first.

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 depending on the weather.




f.

Compare the values of Atmospheric Pressure and Boost Pressure Sensor with the normal atmospheric pressure in the table.

Result:

·

In Example 1, as the pressure difference is higher than 4 kPa (0.58 psi), proceed to the next step.

·

In Example 2, as the pressure difference is less than 4 kPa (0.58 psi), replace the ECM.
