1.

DTC P045011: Canister pressure sensor voltage low

If the canister pressure sensor voltage output (pressure) is less than 0.45 V: 42.11 kPa(abs) (6.11 psi(abs)), the ECM interprets this as an open or short circuit in the canister pressure sensor or its circuit, and stops the EVAP system monitor. The ECM then illuminates the MIL and stores the DTC (1 trip detection logic).

2.

DTC P045015: Canister pressure sensor voltage high

If the canister pressure sensor voltage output (pressure) is higher than 4.9 V: 123.761 kPa(abs) (17.95 psi(abs)), the ECM interprets this as an open or short circuit in the canister pressure sensor or its circuit, and stops the EVAP system monitor. The ECM then illuminates the MIL and stores the DTC (1 trip detection logic).

3.

DTC P04502F: Canister pressure sensor abnormal voltage fluctuation

If the canister pressure sensor voltage output fluctuates rapidly for 10 seconds, the ECM stops the EVAP system monitor. The ECM interprets this as the canister pressure sensor voltage fluctuating, and stops the EVAP system monitor. The ECM then illuminates the MIL and stores the DTC (2 trip detection logic).


MONITOR STRATEGY

Required Sensors/Components Canister pump module
Frequency of Operation Continuous: P045011, P045015
Once per driving cycle: P04502F

CONFIRMATION DRIVING PATTERN

NOTICE:
·

The Evaporative System Check (Automatic Mode) consists of 7 steps performed automatically by the GTS. It takes a maximum of approximately 24 minutes.

·

Do not perform the Evaporative System Check when the fuel tank is higher than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable.

·

Do not run the engine during this operation.

·

When the temperature of the fuel is 35°C (95°F) or higher, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature below 35°C (95°F).



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.

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

·

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.

Enter the following menus: Powertrain / Engine / Data List / Intake Air Temperature.

5.

Check that the intake air temperature is between 4.4 and 35°C (40 and 95°F).

6.

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

7.

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

8.

Turn the ignition switch to ON [A].

9.

Turn the GTS on.

10.

Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check / Automatic Mode [B].

11.

After the Evaporative System Check is completed, check for All Readiness by entering the following menus: Powertrain / Engine / Utility / All Readiness.

12.

Input the DTC: P045011, P045015 or P04502F.

13.

Check the DTC judgment result.

GTS Display Description

·

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.

NOTICE:
·

When replacing the canister pump module, check the canister pump module interior, canister interior and related pipes for water, fuel and other liquids. If liquids are present, check for disconnections and/or cracks in the following: 1) the hose between the canister and the canister pump module; 2) the pipe between the air inlet port and the canister pump module; 3) the canister filter; and 4) the fuel tank vent hose. If liquids are present in the canister interior, replace the canister and canister pump module together.

·

Check for filter blockage in the canister. If the charcoal filter inside the canister is clogged, replace the canister and canister pump module together.

·

Check for filter blockage in the canister filter. If the canister filter has blockages, replace the canister filter.
