Ok, hello to all! I have a civic with a d16z6 block vtec single cam with a 2000 vtec head swap. From what I read the z6 has no knock sensor but I get a check engine light code for knock sensor, and my light never goes off. When I took it to auto zone I also got error codes for the following: FTP sensor circuit high voltage, system too rich bank 1, evap control system pressure high input, Secondary H02S12 heated oxygen sensor bank1, and vtec solenoid. Now my question is, is all of this being caused because of the swap or something, because I drive my car daily and I feel nor hear any problems, so what is going on? My check engine does not go away.

 

check you codes again an 0bd1 p28 isn't capable of throwing a knock sensor code, as the knock sensor circuit is not even on the P28 board

Ok, what if I reset the computer by removing the negative battery cable? Cause Im thinking that maybe whoever did the swap did not reset the computer.

 

what year is your civic? i swapped my 98 with a 95 motor and ended up having to put my knock sensor on the motor using jb quik and what not because my light would not go off either.... yes there is not spot for the sensor so what i did was find a nut that fits the thread of the sensor then i jb quik'd it together and again jb quik'd it to the block right beside the oil filter hope this helps

 

mines is a 97 hatchback.

 

what do u mean by "jb quik'd it"?

 

the codes u have are not p28 codes check to c what ecu u have.

 

there is ur problem, it if its an hx there could be many different things wrong and one sounds like an o2 sensor isnt even connected along with it needing a knock sensor for the car itself

 

Ok, thanks, but how to check what computer I have? I just took a look at it but I see nothing related besides a bunch of numbers in the front of it, none indicating a p28 or something.

 

see where it says p06



thats where you'll find the code indicating what ecu you have

 

You must be running a OBD2 ECU. Show us some pics from under the hood. It sounds like a bunch of stuff is disconnected.

 

Ok, so I figured it out its a p2p ecu. Should it be asking for a knock sensor?, because as far as I know the d16z6 does not have one, and if so what can I do to get rid of it?

 

the p2p will be asking for a knock sensor.

 

yep. and there is no good way to bypass it. aside from welding a bung to the back of your block and plopping in a knock sensor

 

Ok, thanx to everyone that reply. Thanks to all!

 

or going to obd1 and sticking in a p28

 

well yes that is the obvious way to solve this however my response was in regards to if the op felt like staying with the obd2 ecu.

 

or using the resistor trick

 

ive only done that on a nissan

 

doesn't work very well, if at all. the knock sensor is not simply an electrical load read by the ecu, it produces its own voltage. if the ecu does not see this varying voltage, you will trip the knock code.

the only time i've seen someone have any success bypassing the knock sensor is by wiring up piezo transducers in series and mounting them in some fashion to the fuel rail/back of the engine area. unfortunately even this method doesn't seem to work 100% of the time. it's not meant to be a permanent fix by any means.

 

welding it are u nuts? why not just use some rtv?.. or gum?

 

thats why "JB-quik'd" came up

 

WTF are you talking about? A welded bung on a metal strap bolted to the block is a common mod.
