Firstly, a big thank you for all you folks willing to help me bring this XKR back from Plonkerville. I'm down to one code via OBDII! MAP sensor. Well then. Let's inspect! Wiring seems to be good! Let's check the vac line to the map sensor, and....

(no vac line to MAP sensor)

So now, I need to determine where that vac line is supposed to either connect or tee in, and if it really matters WHERE, or if just a general access to the vac subsystem will suffice. Any pointers? I've not found a good diagram or link that's 404 yet. If someone could just take a quick pic under their XKR hood when they get the chance... the MAP sensor is directly behind the throttle body on the firewall, connected via a bracket. Usually Denso P/N LNF1622AA.

 

Welp. I found the line, capped off and tucked under a bunch of stuff. Reconnected, reset OBDII and no more P0105. Why on earth would anyone take the time to cap off the MAP? It's a cap in and of itself! So many stupid plonker things done to this car. Ooof. Down to just the P1000 drive cycle code now. Maybe, just maybe, I'll pass emissions!

 

Nice, now you just need to drive it and enjoy
