P0141 Honda Code - Secondary Heated Oxygen Sensor 2 Heater Circuit Malfunction
Quick Answer
A heater for the zirconia element is embedded in the Secondary Heated Oxygen Sensor (Secondary HO2S (Sensor 2)), and it is controlled by the Powertrain Control Module (PCM). Common causes include Faulty Secondary Heated Oxygen Sensor 2, Secondary Heated Oxygen Sensor 2 harness is open or shorted, Secondary Heated Oxygen Sensor 2 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Discuss the causes and fixes for P0141 Honda OBDII Code
-
I repalced sensor 1 and 2 and the check engine light still remains on honda 2001 crv.
-
P0141 was my code i replaced both sensors on honda crv 2001; and check engine light stayed on.
-
According to the factory service manual, If the sensors are OK, then the problem could be the wire from the sensor to the Engine Control Module (ECM) or the ECM itself.
-
Depends on the model and year of your Honda, but O2 Bank 1 Sensor 2, means that the problem is the Rear Oxygen (O2) Sensor bank 1
-
Had the same trouble, after changing both 02s, I change the ECU and that solved my trouble
-
It is 2007 Accord ex 2.4 regular 4 cyl.
O2 sensor had Po141 reading, had it and cat converter replaced, and engine light still on. (Right after being reset, it came right back on.)
Never had these problems with my old Toyota -
I have been checking what else could set the P0141, but unfortunately, other than the sensor, there is nothing else common that could set the P0141 code. I recommend to double check the sensor installation. Make sure there are no exhaust leaks near the sensor.
One more thing, there is a fuse for the sensor, but that fuse powers other things (e.g. MAF, EVAP Canister) and if the fuse is blown, you will also get other codes.

I have a 01 Honda Accord and it won't turn over at all but there's still power to the vehicle and when I use my code reader it came up with the code p0141 as one of the codes. Now my Cadillac converter got cut off play some douchebag a while ago to my o2 sensor hasn't been connected since then however I put a straight pipe on it so I don't know like that would cause this but not sure why it won't try to turn over whatsoever all of a sudden...pls help
-
Bad O2 sensor or even disconnected sensor will not stop the engine to turn over at all, the O2 sensor are for emission only.
