Empowering You Overcoming the Po141 Code with Precision

The only code was the rear sensor. Replaced it and code changed to the heated circuit code, been only that one ever since. The P0141 code shows up in the scanner, it means there is something wrong with the heating circuit of the oxygen sensor located in the middle of the catalytic ... That code isn't for the sensor directly. It is for the "heated oxygen sensor heater" circuit. The current supplying the heater in the O2 sensor ... Looks like your downstream HO2 sensor has bit the dust. Check fuse but first HO2 would have set codes also. Check for broken wires first, but my ... This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. Sensor #2 would be the second sensor ... Disconnect the negative terminal on your battery for ten minutes. This will hopefully clear the codes and do a soft reset of the computer. p0141 Not Clearing · Faulty oxygen sensor heater (most common) · Circuit problems (e.g., damaged wiring, loose connections – fairly common) ... This is an issue with the heater element or wiring of the o2 sensor. Replace that oxygen sensor to make the fault go away. Means the heater circuit for the downstream O2 sensor has a problem. It's located aft of the cat converter under the middle of the van. More ... Code P0141 is set when the Rear Oxygen Sensor does not show signal activity indicative of closed loop fuel system operation within the required time.
