Bought a supposedly genuine Denso O2 sensor 1x43-9F472-AC for genuine money, but measuring the heater resistance I am getting 1.1ohm.
I can not find the spec of what it should be anywhere, not listed on the Denso site and I can't find it in the XK manuals I have - anyone got a source for the correct value as I am suspicious of this one..

 

After hours of google i finally ended up back here at a post from @RaceDiagnostics 7 years ago when he measured a DOX-0430 which is the new name for the sensor above and got 0.9ohms so it looks like mine should be fine. https://www.jaguarforums.com/forum/x...72/#post841963
In the meantime I dropped Denso a mail and if they ever get back to me I'll confirm here.

 

Well Denso never got back to me but it turns out despite the ebay and seller reassurances it is the wrong unit.
Searching for the Jag code LJA1682AE all I can find are US Bosch, Denso and Walker units with no UK equivalents, Got a Walker 250-24485 which works fine with a heater resistance of 5 Ohms
