hey everyone. i have a swapped 5th gen, (h22a) , and last nite i was driving and hit vtec right as i passed over a bump and the cel popped on right after. code was a 325 i believe for a knock sensor malfunction 1. so i erased it thinking it was the bump that tripped it and drove for another 10 minutes reved it out again and it popped on only this time no bump in road. any suggestions? ideas? location of the knock sensor on this motor ? (i think its dead center in back up top) but a pic or exact place would be great - thanks for the help

car has vafc2 -2 corrected in vtec. so i changed it back to 0 to problem solve.

 

Do a search on knock sensor location...there is a good post on location and whatnot w/ pictures. gl

 

tried searching...but i guess the ht server is down for the count

bump

 

got the sensor out....well half of it, looks as if the actual sensor wire ripped out of the sensor housing so the actual screw in part is still there...anyone know if the h22a4 knock sensor is the same as the h22a...thanks

 

mine did the same thing i just found a small strand of wire soldered it to the other wire and solder it to the chip and then glued it back together works great been about 5 months now

 

i hate not having super tiny and bendable arms / hands haha. its so tight to get in there w/o a lift.

 

a broken knock sensor is one of the main reasons i went swapped to OBDI and a p28 (doesnt look for a knock sensor)

i really hate those things. They break so easily and are so expletive expensive.

 

yeah for real 150 bucks for this damn thing wtf....i even work at advance auto and the discount aint gonna save me much. oh well i can break it as man times as i want and take it back lol.

98vtec funny u mention that my friend just calld and recomended doing the same thing. ill hafta lookinto it...any advice ?

 

will ur car not kick into vtec without that sensor working? where is it located?

 

it will, it jsut retards the timing and makes the car run shitty.

 

yeah i noticed ever so slightly the torqueness seemd to drop off ever so slightly. but yea it still hits vtec...the damn thing is under the intake manifold and above and in front of the oil filter ...aka biggest pain in the a** place u could put it haha. -


98 vtec what all would i need for a obd1 / p28 switchover <i heard p13 could work too>
