Title: K313 (CVT): CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM: DATA LIST / ACTIVE TEST; 2020 - 2023 MY Corolla Corolla Hatchback [01/2019 - 11/2022]

DATA LIST / ACTIVE TEST

DATA LIST

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.

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.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / Engine and ECT / Data List.

HINT:

  • To display the list box, press the pull down menu button next to Primary. Then select a measurement group.
  • When selecting a measurement group, the ECM data belonging to that group is displayed.

(g) According to the display on the Techstream, read the Data List.

Diagnostic Note

Vehicle Speed

Vehicle speed

Min.: 0 km/h (0 mph)

Max.: 255 km/h (158 mph)

Actual vehicle speed
  • This is the current vehicle speed.
  • The vehicle speed is detected using the wheel speed sensors.
  • Vehicle speed data is delayed when it is displayed. Therefore, even if the vehicle speed listed in the freeze frame data is 0 km/h (0 mph), this does not always mean that the malfunction occurred when the vehicle was stopped.

Engine Speed

Engine speed

Min.: 0 rpm

Max.: 16383.75 rpm

700 to 800 rpm: Engine idling

When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.

MAF

Airflow rate from mass air flow meter sub-assembly

Min.: 0 gm/sec.

Max.: 655.35 gm/sec.
  • 1.0 to 3.0 gm/sec: Engine idling
  • 3.0 to 8.0 gm/sec: 3000 rpm (without load)

This is the intake air amount detected by the mass air flow meter sub-assembly.

MAP

Intake manifold pressure

Min.: 0 kPa (0 psi), Max.: 255 kPa (36.98 psi)
  • 80 to 110 kPa(abs) [11.6 to 15.95 psi(abs)]: Ignition switch ON
  • 20 to 40 kPa(abs) [2.9 to 5.8 psi(abs)]: Engine idling (engine warmed up, A/C off and shift lever in P or neutral)
  • When the ignition switch is ON, the manifold absolute pressure and atmospheric pressure are approximately the same (standard atmospheric pressure = 101 kPa(abs) [14.65 psi(abs)]).
  • MAP is almost the same as Atmospheric Pressure when the engine is stopped, these items can be used to help determine if the manifold absolute pressure sensor characteristics are abnormal, if there is noise, or if the sensor output is stuck at a certain value by comparing the values.

Coolant Temp

Coolant temperature

Min.: -40°C (-40°F)

Max.: 140°C (284°F)

75 to 100°C (167 to 212°F): After warming up
  • After warming up the engine, the engine coolant temperature will be 75 to 100°C (167 to 212°F).
  • After a cold soak, the engine coolant temperature, intake air temperature and ambient air temperature will be approximately equal.
  • Check if the engine is overheating if the value indicates 140°C (284°F).
