does anyone know where the 2-wire from the evap purge vavle goes to? does it go directly to the ecu? if so, which pins do i hook them up to?

 

ok i did some more searching around and i found im suppose to wire it up to pin A20. am i right? however i thought there were 2 wires? not just 1?

also is it suppose to throw a CEL if its not hooked up?
cuz mine isnt hooked up and its throwing no CEL at all.
im also using a 94gsr ecu for my 96 b18c swap if that helps.

i think im using the jdm harness that came with the motor so im pretty sure there is no 2-wire for the evap purge vavle? am i correct?

The other wire is power from the main relay. The ECU closes the ground side of the circuit when it wants to energize the relay.

 

ahh i see.

wat about my other questions? anyone know?

weird.. well maybe if i used an obd2 ecu then the CEL would most likely come on.

 

But I think an OBD-2 ECU would also require a gas-tank pressure sensor & a small handful of additional valves.

 

yeah tahts why i will never use obd2 ecu. i do not have the time nor the money to get all that.

isn't it code 91? Evaporative Emission Control System insufficient purge flow.
or is that a code for obd2 ecu's?

 

91 doesn't exist in my '95 Integra list, probably only OBD-2.

 

ahh ok. well thats good to know.
