Re: 1.8T - "The Topic"
eu estive lá com ele na semana passada a ver o carro e a sonda que lá estava tinha tudo para lá chantado dai meter-se uma decente.
o carro sem ela trabalha bem.
17521 - O2S: B1 S1: Internal Resistance too High
35-10 - - - Intermittent
16518 - O2S B1 S1: No Activity
35-10 - - - Intermittent
"internal resistance too high" quase sempre indica ou sonda nas couves ou cablagem nas couves.
Manu, tens um multimetro para testar a cablagem por quebras?
Suposto teste para 1.8t
So to test the O2 Sensor 1...
1) Check fuse G39
2) Switch ignition off and ensure that all misc electric items are off; i.e. fan, radio, lights, A/C, etc.)
3) Coolant temp has reached at least 80C
4) Ensure the ground connection for the wire harness is good
5) Disconnect the O2 Sensor wire harness connector
6) Switch ignition on (DO NOT START THE CAR!) and using a multimeter touch connector pins #3 and #4 and if you get .4 to .5 volts, sensor is bad replace it.
7) If you do not get the reading noted above check the wire harness and/or the O2 sensor heater (Z19).
8) O2 sensor heater, follow steps 1 thru 5 above ONLY
9) Using a multimeter check the wire harness voltage; pin #1 is the power lead and if you do not get 12.5 volts the wire harness is bad, check/fix it and perform all test again.
10) Using a multimeter check the ohms and touch connector pins #1 and #2 and if you do not between 2.5 and 10 ohms, sensor is bad replace it.

Um sensor com o erro não quer dizer que o problema esteja no mesmo
