Hey everyone my '98 3.2 TL had a CEL and I ran the codes and p0141 came back, O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2). I bought a universal bosch 02 sensor kit, but I am having a hard time figuring out what the stock O2 sensor wire colors are. The universal kit came with a color chart for their sensor, but I don't know what the OE wire colors are. I can't find a wire color diagram. My OE wire colors are: 1 white, 1 green and 2 black? Does anyone know, thanks!

 

I suggest looking at Autozone.com wiring diagrams for your vehicle. I took a quick peek and it looks like white is signal to ECU and green is signal ground. The two black are heater circuit and interchangeable.

good luck

 

Thanks for your help, TexasHonda! The colors of each wire you said, were correct.
