my F54 bloc had an CHT sensor and my N42 block with N47 head does not have a spot whare the CHT . haveing problem with it running. any help please

 

Don't quote me, because im not sure if its the right thing to do, i had to run my Cht up to the cts in the thermostat housing. from what i under stand (someone correct me if im worng please) the ecu interpits the signal the same, but you have to make sure the correct sensor is in the correct hole. my car runs fine after i extended the wires.

 

IIRC only the P90 head has the CHTS in the head (none are in the block) so the rest are probably in the thermostat housing...

 

^^^ And P79.

Yes, connect the CHTS plug to the same sensor in the thermostat housing (obviously you will need to lengthen the wires).

 

NO!! The P79 head also has a CHTS in the head
