1. SFI SYSTEM
HINT: The standard normal voltage between each pair of the ECM terminals is shown in the table below. The appropriate conditions for checking each pair of the terminals are also indicated.
The check results should be compared with the standard normal voltage for that pair of terminals, listed in the "Specified Condition" column.
The illustration above can be used as a reference to identify the ECM terminal locations.
*1: The ECM terminal voltage is constant regardless of the output voltage from the sensor.
HINT: The wavelength becomes shorter as the engine rpm increases.
HINT: In the DATA LIST, item O2S B1S2 shows the ECM input values from the heated oxygen sensor.
HINT: The wavelength becomes shorter as the engine rpm increases.
HINT:
HINT: The wavelength becomes shorter as the engine rpm increases.
HINT: The wavelength becomes shorter as the engine rpm increases.
HINT: If the waveform is not similar to that shown in the illustration, check the waveform again after idling for 10 minutes or more.
HINT:
HINT: The duty ratio varies depending on the throttle actuator operation.
HINT: The duty ratio varies depending on the throttle actuator operation.
HINT: The wavelength becomes shorter as the engine rpm increases.
Terminals of ECU
1. CHECK POWER BACK DOOR ECU
Disconnect the P13 and P14 ECU connectors, and
check the voltage or resistance of each terminal of
the wire harness side connectors
If the result is not as specified, there may be a
malfunction on the wire harness side.
Reconnect the ECU connector ...
