I need to know what plug is connected to the knock sensor. There's 2 loose plugs that aren't connected to anything but people keep saying they don't connect to the knock sensor

 

B

 

That is probably for the power steering pressure Switch. The knock sensor one is generally gray and only has one wire (pink/ blue stripe)

 

Ok thank you and is it this one?

 

Any help please!

 

Give us more info, what year chassis? engine swap? what engine? what engine harnes is being used?

Knock sensor should be a one wire plug.

 

Its a 1994 gsr shell. Engine is a b16a with an L's block, and I don't know what harness it has because not too long ago it was replaced due to electrical issues.

 

You made a previous post about the map sensor and a left over plug and low idle thats turns the engine off sometimes.

Is the engine tuned on a EMS or are you using a stock ecu or a chipped ecu? base map ect..

stock injectors?

You might have a GSR engine harness which would leave i believe two plugs left over from the GSR intake manifold thats not used on a B16 intake manifold or ITR intake manifold.

 

Yes the ecu is stock and injectors

 

Get it tuned and see how it runs. Don't have a tuner? then have a tuner setup a base map tune on a obd1 with at least a hondata S100 to at least run the engine better than a stock ecu. You can't expect a stock edu to run a hybrid engine.

 

I can't man I've invested way too much money in this junk and getting it chipped and tuned is like $800 smh

 

You can get it done for much less than that man come on!! theres free software you can use to chip the ECU and a tuner shouldn't charge much at all to at least put a base map on. But why would you build this setup but not factor in tuning it? you should of used a stock engine.

 

My dumbass bought it like that. That was one of the first things I was gonna do but I came across other major problems. So its not the knock sensor that's making it idle and die?

 

Save some money research the cheapest way to tune the engine and do it! it will never run right plain and simple. Look for a ECU thats already chipped with hondata and send it to a tuner and have them at least upload a base map if thats all you can afford.

Theres a hondata s300 ecu for like $300 here in the F.S section.

Knock sensor is not your problem.

Try cleaning out the IACV on the back of the intake manifold. Just spray it with brake parts cleaner and get all the gunk out as well as clean off the screen in there. Let it dry for 10 min and bolt it back on, just unbolt the two bolts don't disconnect the coolant hoses if you don't have two but if you do just plug the hoses with a bolt and pull out the IACV and clean it. Seach the sticky on the thread to clean the IACV here. Its worth a try to get the engine to idle right.

 

I know it won't run right without a tune but I'm just trying to fix the idle issue and the car dying. But I can't find the knock sensor plug

 

That harness uses a lot of plugs like that. Does that one have one wire coming out the back?

 

Yes its red with a blue stripe

 

Ok then it should be it

 

OK thanks but the wire is tapped with other wires. Let me send you a picture

 

Sounds like that might be the plug for the Knock sensor..

 

Sorry about the **** quality but why is it tapped there? And its not long enough if maybe i cut the tape

 

?????

 

Taped or tapped? If its just taped with electrical tape then cut some of the tape back. If its tapped with another wire then it should definitely not be.

 

Then which one is the knock sensor plug??????

 

Get some better pics of the splice in the wire, is it just taped to another wire or is the wire tapped into another wire? did you try pluging it in and clearing the code to see if it comes back??
