I have two connectors that I can't find anything to plug into. One is the orange connector by the coolant reservoir and the other is a two prong white sensor by the passenger firewall.

 

Second one, white, is an 02 connection, not sure what the first harness includes, why do you ask?

 

I just replaced my engine and have cam sensor codes, evap codes, and tps codes coming up. Just wondering why I can't find the other end of these connectors coming off the motor.

 

The service manager at Royal Jaguar Land Rover of Tucson looked at the photos and said both of these come unplugged from the factory. I think what happened is I fried all my sensors when I overheated my last engine and tried to reuse all of them. I'm just going to have to replace every single sensor. No big deal, it will probably be less than $500 altogether and everything will be brand new.

 

That sounds extremely fishy. How hot did you get this engine to damage every sensor on it? Did it catch on fire, or melt?

 

Trying to figure out where to start. Every sensor hopefully isn't bad. I think one is setting off the others. As of right now the codes are cam sensor, tps, MAF, O2 x 2, two evap codes, and the M & S lights are blinking. It idles high at 2k rpm at startup then drops down to about 4-600 rpm and does not respond well to throttle. I replaced TPS last week with no results, it still bogs out when I give it gas. My next best idea is to replace the MAF sensor. Any help appreciated.

 

On a further note, I just looked at a ford taurus that was acting the same way and the problem ended up being the temp sending unit. I will likely replace that as well if the 4.0 has one since the coolant reservoir was boiling over after about ten minutes of idling.
