what is a code 40 on a civic obd1?

[dereksi]

what year? I can find out tomarrow from Alldata at the shop. I dont know codes off the top of my head. Include engine size and year

from what i remember there isnt a cel40, atleast i never remember pulling one and i know there isnt one listed from the info i have at home on the web or in a book.....might wanna recheck it real quick....but his list is accurate....bookmark the following page for future reference...its for obd1 and later ecu's


THANK YOU
