1997 Civic CX (non vtec) -- Ecu Code

[SiR Master]

Hello all,

Can anyone let me know the cause of code P0141 I think it may be an O2 sensor. But I would like to confirm.

Thanks

O2 heater circuit (bank 1, sensor 2).

Thanks.

Would that be the exhaust manifold sensor or the one at the Cat.

secondary o2. @ cat = reference o2
