Re: sonda lambda Sv 1000 błąd c44
Skoro rozkodowałeś już C44 jako błąd lambdy, to zakładam, że serwisówkę masz
FI System, 4-61 do 4-63
Step 1
1) Lift and support the fuel tank with its prop stay . (r-74-65)
2) Turn the ignition switch OFF .
3) Check the H02 sensor coupler for loose or poor contacts .
4) Insert the needle pointed probes to the H02 sensor lead wire
coupler .
5) Warm up the engine enough .
6) Measure the H02 sensor output voltage at the coupler
(between W/G or B and B/Br or Gr wires) when idling condition .
7) Measure the H02 sensor output voltage while holding the
engine speed at 3 000 r/min .
H02 sensor output voltage at idle speed :
0.4 V and less (E W/G or B - O B/Br or Gr)
H02 sensor output voltage at 3 000 r/min :
0.6 V and more (OO W/G or B - O B/Br or Gr)
Is the voltage OK?
YES Go to Step 2 .
NO Replace the H2O sensor with the new one.
Step 2
1) Turn the ignition switch OFF .
2) Turn the ignition switch ON and measure the heater voltage between O/W wire (ECM side) and ground .
3) If the tester voltage indicates the battery voltage for few seconds, it is good condition .
• Heater voltage : Battery voltage
( 01W - O Ground)
NOTE:
Battery voltage can be detected only during few seconds after ignition switch is turned ON.
Is the voltage OK?
YES Go to Step 3 .
NO Replace the H02 sensor with a new one .
Step 3
1) Turn the ignition switch OFF .
2) Disconnect the H02 sensor coupler .
3) Check the resistance between the terminals (White - White)
of the H02 sensor .
• H02 heater resistance : 4 - 5 Q (at 23 °C/73 .4 °F)
(White - White)
NOTE:
• Temperature of the sensor affects resistance value largely-
• Make sure that the sensor heater is at correct temperature .
Is the resistance OK?
YES
• W/G, W/B, O/G or B/Br wire open or shorted to ground, or poor ®, 015), 24 or C4) connection . (r r4-23)
• If wire and connection are OK, intermittent trouble or faulty ECM .
• Recheck each terminal and wire harness for open circuit and poor connection . (f"74-6)
NO
Replace the HO2 sensor with a new one .
Z tego co pamiętam, to do SV pasuje sonda od jakiegoś BMW i skody felicii
