Szia!
Köszi a gyors választ.
A kipufogóm szerintem nem fúj ki, hallanám. Minden apró cstresz zaját meghallom ami kopok, zörög az autón. Alig 2 hete voltam Toyotáéknál átvizsgáláson. Akkor rámértek a CO-ra is és mindne tökéletes volt.
Oxigénszenzor teszthez van pontos leírás, hogy hogyan lehet megcsinálni? Illetve mik a jó avagy rossz értékek?
Üdv:T
Van ám, angolul:
(a) Connect the hand–held tester to the DLC3, or connect the probe of the oscilloscope between terminals
OX1A, OX2A, OX1B or OX2B and E2 of the ECM connectors.
(b) Start the engine and warm it up with all the accessories switched OFF until the engine coolant temperature
is stable.
(c) Run the engine at 2,500 to 3,000 rpm for about 3 minutes.
(d) After confirming that the waveforms of the heated oxygen sensor (bank 1, 2 sensor 1 (OX1A, OX2A))
which oscillates around 0.5 V during feedback to the ECM, check the waveform of the heated oxygen
sensor (bank 1, 2 sensor 2 (OX1B, OX2B)).
HINT:
If there is a malfunction in the system, the waveform of the
heated oxygen sensor (bank 1, 2 sensor 2 (OX1B, OX2B)) is
almost the same as that of the heated oxygen sensor (bank 1,
2 sensor 1 (OX1A, OX2A)) on the left.
There are some cases where, even though a malfunction exists,
the CHK ENG may either light up or not light up.
2 READ VALUE OF HAND–HELD TESTER(OUTPUT VOLTAGE OF HEATED OXYGEN
SENSOR)
(a) Warm up the heated oxygen sensor (sensor 1) with the engine speed at 2,500 rpm for approximately
90 seconds.
(b) Read the output voltage of the heated oxygen sensor during idling.
Heated oxygen sensor (sensor 1) output voltage:
Alternates repeatedly between less than 0.4 V and more than 0.55 V (See the following table).
(a) Disconnect the H7 or H9 heated oxygen sensor connector.
(b) Measure the resistance between the terminals of the
heated oxygen sensor connector.
Standard (Bank 1, 2 Sensor 1):
Terminal No. Resistance
1 (HT) – 2 (+B) 11 to 16 at 20C (68F)
1 (HT) – 4 (E1) No Continuity
Az utolsó meg a kiszerelés és ohm mérés.
