I have a 2002 accord lx coupe 5 speed . I pulled out the f23a ulev motor and put in an f20b. The check engine light is on reading a p0166 code is a sensor bad or is there a problem with the wiring or need to be pinned in a different location? Also the temperature gauge isn't working same question do i need to pin that in else where or can i wire one up with an after market gauge.? If so which sensor do i go off of the one on the head or the thermostat housing?

 

Would running a obd2 h22 fix my head ache

 

If your running the f23 ecu it wont
Also you must use the f23 dizzy

 

The f23 dizzy does not have the positioning sensor like the f20b. So i would be throwing a code for that and still wouldn't pass new York state inspection.
