i have a d15b7 multipoint 88 civic. everything runs good except for that i keep getiing a code 1. if im not mistaken its a faulty o2. ive bought a new o2 still get that problem. my car runs rich. another thing i dont understand is that my code 1 blinks twice. its not code 2 cuz there is no code 2. i dunno. if anyone can help that would be great. this is the only thing stopping me from going turbo. thanks

 

is it code 20??
can u read codes, do you know how??

 

i believe if it were code 20 wouldnt the ecu flash 20 times. the ecu is a pm6 out of a 90 crx si. it flashes once then pauses and flashes once again. and yes i know how to read the codes.

 

once pauce once pauce once pauce



thats one dude

 

im sorry i forgot to say that i also have another code for the vss. so it blinks pause blinks pause then blinks 17times for the vss. sorry i should have said that earlier

 

for 17 it blinks once long and 7 short
for 20 it blinks 2 long
it doesnt blink 20 times

 

im just going by what the honda book tells me. 17 constant blinks vss. by the way my car is obd-0. car runs fine i just cant get rid of the o2

 

Thats obd1 blinky style


obdo blinky style will do the whole 17 blinks trust me I have had code 17 in every car I have owned LOL

 

Tiiming, untuned vehicle will alter the o2 readings and throw a code not to mention runnin the sensor


also your lookin at more likely a wiring problem
