Does anyone know which other O2 sensors you can use for B230FT engines? When splicing do you just match the colours from the Volvo lead to the replacement?

I read somewhere on the forum that 5.0 litre Mustang sensors worked well, they only have a 4" lead on them.

Someone else had said that all 3 wire sensors heads are the same, is there anyway to confirm this?

I just finished installing a Ford sensor my Foreign Auto parts guy got me. It was a short harness, about 4-6" after I snipped off the Ford connector, and I soldered the old harness in place. There is one black wire, two white. I found that neither of the white is common to ground (the case of the O2) so I decided polarity is fine either way. Just make sure your iron's hot, as the (steel?) wires are not as easy to heat as copper. A little heatshrink and careful reuse of the original protective sleeve, and you've probably saved $50-$75.

Unfortunately it looks like that may go to a new AMM in my case. The O2 voltage is still .8-.9, with the only changes coming at throttle closed, falling back to idle from 2K rpm.

A good snip and solder O2 sensor is the Bosch #13913. It ran me $32. I don't know what car the connector was made for but the price was made for me. The Bosch website said that the OEM, universal, 2, and 3 wire sensors will all work on my Volvo leading me to believe that Bosch a O2 sensor is a Bosch O2 sensor. The price difference comes with the luxury of an OEM connector.

Thanks, good luck w/ the AMM. Hope it's OK

Just be sure not to use a Walker o2 sensor. Mine only lasted abour 5k. What a headache (time/money/...) to diagnos. "I just replaced the o2 sensor, must be the Catalytic converter, No, it must be the MAF, It can't be the fuel filter, just replaced that!"
