2Tr-Fe Engine Control. Sfi System (W/O Secondary Air Injection System) Data List / Active Test

Using the intelligent tester 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.
The actual values may differ from the values listed in the chart under "Results of real-vehicle check" due to climate, weather conditions, etc.

HINT:

Normal Condition: If no conditions are specifically stated for "idling", the shift lever should be in N or P, the A/C should be off and all accessory switches should be off.

Evap Purge Flow	Diagnostic Note: This is the percentage of total engine airflow contributed by EVAP purge operation. (Evap Purge Flow = Purge flow / Engine airflow x 100 (%)) It is based on MAF and a stored value for airflow and controlled by adjusting the duty cycle for the purge VSV.

Purge Density Learn Value
Tester Display	Measurement Item/Range	Normal Condition	Stored as Freeze Frame Data
Purge Density Learn Value	Purge density learned value/ Min.: -200, Max.: 199.993	-	Yes
Purge Density Learn Value	Diagnostic Note: Purge Density Learn Value is the proportion of the decrease in injection volume (based on the change in the air-fuel ratio feedback compensation value) related to a 1% purge flow rate. When Purge Density Learn Value is a large negative value, the purge effect is large. The purge density is determined from the change in the air-fuel ratio feedback compensation value when purge flow is introduced. Purge density learning is performed so that the feedback compensation value is 0 +/-2%. HINT: Usually, the value is approximately +/-1%. 1%: The concentration of HC in the purge gas is relatively low. 0%: The concentration of HC in the purge gas is approximately equal to the stoichiometric air-fuel ratio.

Long FT #1	Diagnostic Note: The ECM will learn the Long FT values based on Short FT. The goal is to keep Short FT at 0% to keep the A/F mixture at the stoichiometric ratio. This value is used to determine whether the air-fuel ratio control system is malfunctioning. The condition of the system is determined based on the sum of Short FT and Long FT (excluding times when the system is in transition). +15% or more: The air-fuel ratio may be lean. -15 to +15%: The air-fuel ratio can be determined to be normal. -15% or less: The air-fuel ratio may be rich. The learned value is cleared when the battery cable is disconnected.

Tester Display	Measurement Item/Range	Normal Condition	Stored as Freeze Frame Data
Knock Feedback Value	Knocking feedback value/ Min.: -1024° CA, Max.: 1023.9° CA	-	Yes
Knock Feedback Value	Diagnostic Note: This is the ignition timing retard compensation amount determined by the presence or absence of knocking. Ignition timing = Most retarded timing value1 + Knock Correct Learn Value2 + Knock Feedback Value3 + each compensation amount Example: 21°CA = 10° + 14° - 3° 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 Feedback Value as close to -3°CA as possible. When Knock Feedback Value is less than -4°CA, Knock Correct Learn Value is slowly decreased. When Knock Feedback Value is more than -2°CA, Knock Correct Learn Value is slowly increased. 3: The base value is -3°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. -1°CA: There is no knocking and ignition timing is advanced. -6°CA: Knocking is present and the ignition timing is being retarded. HINT: If Knock Feedback Value does not change around the time when knocking occurs even though knocking continues (for example, stays at -3°CA), it can be determined that knocking is not being detected. Possible Causes: There is a problem with the knock sensor sensitivity. The knock sensor is improperly installed. There is a problem with a wire harness.

Knock Correct Learn Value
Tester Display	Measurement Item/Range	Normal Condition	Stored as Freeze Frame Data
Knock Correct Learn Value	Knocking correction learned value/ Min.: -1024° CA, Max.: 1023.9° CA	-	Yes
Knock Correct Learn Value	Diagnostic Note: Refer to "Knock Feedback Value". When there is knocking or a lack of power, compare the following values to another vehicle of the same model. Engine speed Calculate Load IGN Advance Knock Feedback 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 is not stopping), there may be a buildup of deposits or other such problems due to deterioration over time (oil entering the cylinders, poor quality fuel, etc.).

ACTIVE TEST

HINT:

Using the intelligent tester to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

Warm up the engine.
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT / Active Test.

According to the display on the intelligent tester, perform the Active Test.

HINT:

Usually, Throttle Position Command (Target Value) and Throttle Position No. 1 (Actual Value) are almost the same.
If any DTCs related to the ETCS are stored, this Active Test does not function.

	Throttle Motor Duty (Close)	0%	10%

*3: Activate the VSV for Evap Control (Idling after warming up)

HINT:

Even when the Active Test is turned on (the purge VSV is opened 30%), air-fuel ratio feedback continues and control is performed so that the air-fuel ratio is the stoichiometric ratio. Therefore, by observing the change in "Short FT", it is possible to determine whether the purge VSV is actually open as well as the concentration of HC in the purge gas.

Tester Display	Measurement Item/Range	Normal Condition
Activate the VSV for Evap Control	-	▲A	▲B
	Active Test operation	ON	OFF
	EVAP Purge VSV	ON	OFF
	Short FT #1	-1.563%	0.000%
	Injection (Port)	2288.0 μs	2430.0 μs
	O2S B1S1	0.85 V	0.03 V

HINT:

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.

*4: Control the VVT Linear (Bank 1)

Tester Display	Measurement Item/Range	Normal Condition
Control the VVT Linear (Bank 1)	-	▲A	▲B
	Active Test operation*	+20%	-20%
	VVT Change Angle #1	54.9 DegFR	0.0 DegFR
	VVT OCV Duty #1	53.9%	13.9%
	VVT Aim Angle #1	33.9%	33.9%

HINT:

*: Change the control value for Control the VVT Linear to +20% or -20% in increments of 5%.
The Control the VVT Linear Active Test considers the value of VVT Aim Angle to be 0 and raises or lowers the duty ratio with respect to VVT Aim Angle.
The sum of the control value for the Control the VVT Linear Active Test and the value of VVT Aim Angle is approximately equal to the value of VVT OCV Duty.
When the control value for the Control the VVT Linear Active Test is changed a few times, there should not be a large discrepancy between VVT OCV Duty when the system starts advancing or retarding the timing and the rate of change of VVT Change Angle.
