what sensor is this called? im thinking maybe i have two plugs reversed which is why my car is running like ***. thanks

 

btw, that plug will also fit the iacv and iat. thanks

 

what engine?

 

I'm thinking air purge valve? Not sure though.

Switch the plugs, reset ecu, and turn the car on again. You probably have them switched.

 

obd1 ls vtec

 

apv,i heard you only need it wen you use a obd2 ecu not really sure about it i dont use it and i got no cel

i dont think i need that sensor. nothing seems to happen when i unplug it...

 

It is an EVAP purge control solenoid valve. You do need it for emissions if it is strict where you are at.

 

no emissions where i am...why dont i get a code when i unplug it?

<FONT SIZE="3">DO NOT...... I REPEAT..... DO NOT SWITCH THE IAC AND EVAP PLUGS LIKE THERE THE SAME</FONT>

EVAP and IAC run off 2 different type of power systems (ones ground and ones power) and when you switch them you could fry out the ecu. IAC is a blue/yel with a yel/blk (i believe yel/blk) and evap is a pink with another color. But yea dont mix them like whatever because your ecu will smoke cause its burning.


What exactly is your car doing thats making it run like ***?


EDIT: Im talking IAT not IAC it was to early when i wrote this.

at the moment its just looped. i dont know what to connect it to. im having idle surging issues so i thuoght i might have switched some connections giving the iacv the wrong voltage, ie reversing the two, which might explain the idling.

ya ok thanks. i didnt switch them but im thinking i have the evap and iat wires reversed. i have switched them not but im getting the same code. the code goes away when i put the iat plug (red/yel and grn/wht) to the evap....this makes no sense at all. i have searched and the (red/yel and grn/wht) is definatly the iat sensor but i get a code when its plugged into the actual sensor but the code goes away when i have it plugged into the evap.

 

ok right now i have a blk/yel and solid red wire going to that evap canister. the iat plug is now connected to the right sensor but im getting a code. it must be my iat sensor that has gone bad. im going to try a friends sensor this afternoon.
