Toyota Avalon (XX50) 2019-2022 Service & Repair Manual: Data List / Active Test

DATA LIST / ACTIVE TEST

DATA LIST

HINT:

Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

NOTICE:

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Knock F/B Value

Knocking feedback value

Min.: -1024 deg(CA), Max.: 1023.9 deg(CA)

-20 to 0 deg(CA): Driving at 70 km/h (43 mph) (engine running)

This is the ignition timing retard compensation amount determined by the presence or absence of knocking.

Ignition timing = Most retarded timing value*1 + Knock Correct Learn Value*2 + Knock F/B Value*3 + each compensation amount

Example: 21 deg(CA) = 10 deg(CA) + 14 deg(CA) - 3 deg(CA)

*1: The most retarded timing value is a constant determined by the engine speed and engine load.

*2: The knock correction learned value is calculated as shown below in order to keep Knock F/B Value as close to -3 deg(CA) as possible.

When Knock F/B Value is less than -4 deg(CA), Knock Correct Learn Value is slowly decreased.

When Knock F/B Value is higher than -2 deg(CA), Knock Correct Learn Value is slowly increased.

*3: The base value is -3 deg(CA) and is adjusted based on the presence or absence of knocking. When there is no knocking, the value is increased, and when knocking is present, the value is decreased.

HINT:

If Knock F/B Value does not change around the time when knocking occurs even though knocking continues (for example, stays at -3 deg(CA)), it can be determined that knocking is not being detected.

Possible Causes:
  • There is a problem with the knock control sensor sensitivity.
  • The knock control sensor is improperly installed.
  • There is a problem with a wire harness.

Knock Correct Learn Value

Knocking correction learned value

Min.: -1024 deg(CA), Max.: 1023.9 deg(CA)

0 to 17 deg(CA): Driving at 70 km/h (43 mph) (Engine running)

  • Refer to "Knock F/B Value".
  • When there is knocking or a lack of power, compare the values of following items to another vehicle of the same model.
    • Engine Speed
    • Calculate Load
    • Ignition Timing Cylinder #1
    • Knock F/B Value
    • Knock Correct Learn Value
  • Knock Correct Learn Value is large: There is no knocking and the ignition timing is advanced.
  • Knock Correct Learn Value is small: Knocking is present and the ignition timing is being retarded.

HINT:

When knocking continues even though Knock Correct Learn Value is less than that of the vehicle being used for comparison (in other words, the ignition timing is being retarded but the knocking does not stop), there may be a buildup of deposits or other such problems due to deterioration over time (oil entering the cylinders, poor quality fuel, etc.).

    HINT:

    • During the Active Test, air fuel ratio feedback control and feedback learning are stopped.
    • Usually, the value of A/F (O2) Sensor Current B1S1 drops below -0.075 mA when the control value for Control the Injection Volume for A/F Sensor is changed to 12.5%.
    • Usually, the value of A/F (O2) Sensor Current B1S1 changes to more than 0.037 mA when the control value for Control the Injection Volume for A/F Sensor is changed to -12.5%.
    • Usually, the value of A/F (O2) Sensor Current B1S2 drops below -0.86 mA when the control value for Control the Injection Volume for A/F Sensor is changed to 12.5%.
    • Usually, the value of A/F (O2) Sensor Current B1S2 changes to more than 0.33 mA when the control value for Control the Injection Volume for A/F Sensor is changed to -12.5%.
    • The air fuel ratio sensor (sensor 1) has an output delay of a few seconds and the air fuel ratio sensor (sensor 2) has a maximum output delay of approximately 20 seconds.

    HINT:

    • Even when the Active Test is performed (the purge VSV is opened approximately 50%), the ECM performs air fuel ratio feedback to maintain the air fuel ratio at the stoichiometric ratio. Therefore, by observing the change in the Data List item "Injector Cylinder #1 (Port)", it is possible to determine whether the purge VSV is actually open.
    • The graphs and values above are for reference only because the fuel injection volume (compensation volume) varies depending on the HC density of the purge air from the canister.
