Working on my wife's 2001 Town and Country 3.8 V6 when I spotted a broken sensor(?) in the block, back firewall side below the take down exhaust tube. I know its been broken for a while but everything seems to function correctly.....for the most part. No codes, gauges seem okay, starts, runs, idles. Kind of not important (to me) at the moment as I was in the middle of replacing the power steering rack and the upstream 02 sensor (which is stripped or cross threaded ) and the downstream 02 sensor both taken out by the groundhog along with two spark plug wires, The PS rack replacement is a major PIA. Thanks in advance and here are the sensor photos and location. Though it might be a crankshaft sensor or temp sensor of some kind but can't find anything that looks close to it online?

Thanks again.
