    Good I can wait to get it fixed then. It's just the light that's annoying. Is this a hard thing to fix?

Thats nothing really to worry about the heater is use untill the exhaust gas is hot. like 400 degrees or somthing, thats were O2 sensors work the best. only for emmisons. won't effect your cars proformance

    the heater and the O2 sensor comes as a unit. so you'd have to replace the whole thing unfortunely.

Trouble code p0141-heat oxygen sensor bank1 sensor 2


Hey I had a similar problem with my '02 Focus. The problem was the actual wiring into the distributor. The wire into cylinder 1 and 3 broke (but were very difficult to see) and was giving me codes as well. Pretty common problem in that age of the focus. It made my focus hesitate and chug until the temps came up. I went to the junk yard, found a focus with a rewired module (with a heavier gauge wire), replaced it and magic. Hope that helps

I am getting codes p0141 and p0134, and I have replaced the sensor 1 upstream already


P0141 Heated o2 sensor. P0134 Heater 02 sensor circuit, These 02 sensor has a fuse in the engine junction box listed as IGN 1. This supplies 12volts to the heater circuit, check to make sure its not a open fuse. If you already replaced the sensors make sure you clear the code. or it will stay in memory.

Engine Light on --Scaning appeare Code 0141


P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141. See also: P0135 (Bank 1, Sensor 1).

Symptoms
You will likely notice poor fuel economy the illumination of the Check Engine Light.

Causes: A code P0141 may mean that one or more of the following has happened:
* open or short to ground in the wiring harness
* O2 heater circuit wiring high resistance
* O2 heater element resistance is high
* Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Possible Solutions
* Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
* Repair short or open or high resistance in wiring harness or harness connectors

Hope helps (remember to rate this answer).
