Toyota RAV4 (XA40) 2013-2018 Service Manual: Evaporative emission control system leak detected

Toyota RAV4. Evaporative emission control system leak detected


Dtc summary

Toyota RAV4. Dtc summary


Description

The description can be found in the evap (evaporative emission) system (see page es-335).

Inspection procedure

Refer to the evap system (see page es-340).

Monitor description

5 Hours* after the ignition switch is turned off, the leak detection pump creates negative pressure (vacuum) in the evap system. The ecm monitors for leaks and actuator malfunctions based on the evap pressure.

Hint:

*: If the engine coolant temperature is not below 35°c (95°f) 5 hours after the ignition switch is turned off, the monitor check starts 2 hours later. If it is still not below 35°c (95°f) 7 hours after the ignition switch is turned off, the monitor check starts 2.5 Hours later.

*: If only a small amount of fuel is in the fuel tank, it takes longer for the evap pressure to stabilize.

Toyota RAV4. Monitor description


  1. P0455: evap gross leak

In operation c, the leak detection pump creates negative pressure (vacuum) in the evap system and the evap system pressure is measured. If the stabilized system pressure is higher than [second reference pressure x 0.2] (Near atmospheric pressure), the ecm determines that the evap system has a large leakage, illuminates the mil and sets the dtc (2 trip detection logic).

  1. P0456: evap very small leak

In operation c, the leak detection pump creates negative pressure (vacuum) in the evap system and the evap system pressure is measured. If the stabilized system pressure is higher than the second reference pressure, the ecm determines that the evap system has a small leakage, illuminates the mil and sets the dtc (2 trip detection logic).

Evaporative emission control system pressure sensor
Dtc summary Hint: The canister pressure sensor is built into the canister pump module. Description The description can be found in the evap (evaporative emission) system (see page es ...

Vehicle speed sensor "A"
description The speed sensor detects the wheel speed and sends the appropriate signals to the skid control ecu. The skid control ecu converts these wheel speed signals into a 4-pulse signal ...

Brake switch "b" circuit high
Description The purpose of this circuit is to prevent the engine from stalling while driving in the lock-up condition when the brakes are suddenly applied. When the brake pedal is depressed, this switch sends a signal to the ecm. Then the ecm cancels the operation of the lock-up clutch ...

Pressure control solenoid "d" electrical (shift solenoid valve slt)
Description Refer to dtc p2714 (see page ax-91). Monitor description When an open or short in the shift solenoid valve slt circuit is detected, the ecm interprets this as a fault. The ecm will illuminate the mil and store the dtc. Monitor strategy Typical enabling conditions ...
