Corsa Fault Code

[hazzaboy69]

I read the fault code on a friends corsa the other day and am not sure what to make of it.

It says P0141 - O2 sensor heater circuit (bank 1, sensor 2)

Does this mean there is a problem with the O2 sensor or is there something else wrong here. Whats the heater circuit?

Cheers Harry

if there is more than 2 wires on the sensor then yes its got another circuit if its running lumpy then disconect it while its running if it runs better its the sensor

Some oxygen sensors have heater elements to bring them up to operating temperature quicker.
