hello I am new to this forums but not new to Honda/ Acuras. I have a 99 Acura CL 2.3L with the f23a1 engine and my car is throwing the P1381 code.( CYP sensor intermittent interruption)
I have changed:

Spark Plugs
wires
distributor Housing w/ new CYP sensor
new coil pack

Its still throwing the code and the car runs weak. Anyone know what might be the problem?

I'm out of ideas and money.

Any Honda techs out there please help

 

I'm having the similiar issue with my 2000 Accord Ex, 5spd w/ F23a1. It acts fine till you get to about 3000 rpms and it shoots out the P1381 code, then just miss fires or whatever till you shift gears. then it acts the same till you get to 3k for all gears.

I have also replaced pretty much the same things with luck for about a 250km trip with stops, then the same problem/code shot up just as I was gettin back home. I was hoping maybe a fuel filter could have been the problem, then found out there is no replaceable fuel filter.

So any info/help you can find, I hope will help me as well
