Sensor Circuit voltage - lambda sonda

[Anthraxx9]

Zdravím. Tak začala mi svietiť diagnostika na Opel Frontera 2.2i 16V r.v 96. dal som to na počítač a píše mi jednu chybu a to 39 O2 Sensor Circuit voltage high čo to je a ako to odstránim?


Váha vzduchu je nová.(20km má za sebou) a tak isto aj lambda sonda je nová

Našiel som toto.. avšak niesom do angličtiny..



O2 Sensor Circuit High Voltage
What does this mean?
OBD Code P0138refers to
The Heated Oxygen Sensor (2) located rear of catalytic converter produces an output signal relative to oxygen storage capacity of catalytic converter. Ho2S 2 signal is less active than signal produced by front oxygen sensor. This code sets when HO2 Sensor voltage is greater than 999 mV for more than 2 minutes (time depends on model. Could be as high as 4 minutes)
Symptoms
Possible sumptoms of OBD code P0138
There may be no noticeable symptoms except for MIL illumination. Possible high fuel pressure can over rich the system.
Causes
Possible causes of OBD code P0138
A code P0138 may mean that one or more of the following has happened: Faulty O2 sensor Short to battery voltage in O2 sensor signal circuit High fuel pressure (not as likely)
Possible Solutions
Here are some potential solutions: Replace O2 sensor Repair short to battery voltage in o2 sensor signal circuit

Je to lambda sonda. Ta sonda je original alebo niaka universalna? Ci pracuje ta sonda by mala ukazat ta diagnostika. Ked nie, tak skus pozret napajanie tej sondy.

Lambda je náhrada. práveže píše Voltage High.. keď to je napichnute je tam 1200 mV ale pod 1100 mV nejde

No viem ze s tymi nahradami boli problemy. Netvrdim ze je to tvoj pripad ale aj jeden kolega tu z fora po vymene sondy za nahradu musel potom menit za original. Sice stoji 200 euro, ale potom to uz bolo dobre. Alebo jedine jednotka ze by zle fungovala.

nemoze byt ze by bol kabel niekde seknuty a preraza? ale to by slo do skratu a potom vlastne by bolo napatie nulove
