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.
(a) WAVEFORM 1
(1) Camshaft Timing Oil Control Valve (OCV) operation signal
HINT:
The wavelength becomes shorter as the engine rpm increases.
(b) WAVEFORM 2
(1) Heated oxygen sensor signal
HINT:
In the DATA LIST, item O2S B1S2 shows the ECM input values from the heated oxygen sensor.
(c) WAVEFORM 3
(1) Fuel injector operation signal
HINT:
The wavelength becomes shorter as the engine rpm increases.
(d) WAVEFORM 4
(1) Knock sensor signal
HINT:
(e) WAVEFORM 5
(1) Variable Valve Timing (VVT) sensor signal (1)
(2) Crankshaft position sensor signal (2)
HINT:
The wavelength becomes shorter as the engine rpm increases.
(f) WAVEFORM 6
(1) Igniter IGT signal (from ECM to igniter) (1)
(2) Igniter IGF signal (from igniter to ECM) (2)
HINT:
The wavelength becomes shorter as the engine rpm increases.
(g) WAVEFORM 7
(1) Purge VSV for EVAP system operation signal
HINT:
If the waveform is not similar to that shown in the illustration, check the waveform again after idling for 10 minutes or more.
(h) WAVEFORM 8
(1) Vehicle speed signal
HINT:
(i) WAVEFORM 9
(1) Throttle drive motor operation signal (positive terminal)
HINT:
The duty ratio varies depending on the throttle actuator operation.
(j) WAVEFORM 10
(1) Throttle drive motor operation signal (negative terminal)
(k) WAVEFORM 11
1) Engine speed signal
HINT:
The wavelength becomes shorter as the engine rpm increases.
Transmission Range Sensor Circuit Malfunction
(PRNDL Input)
DTC P0705 Transmission Range Sensor Circuit Malfunction
(PRNDL Input)
DESCRIPTION
The park/neutral position switch detects the shift lever position and sends
signals to the ECM.
HINT:
After confirming DTC P0705, use the intelligent tester to confirm the PNP switch
signal in the ALL menu ...
