one after another

[suprra_girl]

there are two knock sensors on your block
they are located on the intake side
one is between about #2 & #3 cylinder, if you stick your arm under there (when it's cold) you'll be able to feel it
the other one is about #5 & #6 right before the starter motor

more than likely you have a broken wire and you just need to repair it

well i fixed the nock sensor and im still getting the same code what else could i be missing???????

help plz

[jfunez]

did you replace both knock sensors?

if not ,replace the other one. also make sure the wiring is not broken and that they have good contact.

im ordering it but does both have a wire coming out of them or is the first one the only one.
also i heard that theres a nock sensor sircuit board that could be bad. i think thats what its called. is there anything else that im missing with the nock sensor????????

is there a wire on the knck sensor thats close to the firewall

yes both knock sensors need to have wires coming out of them... if they don't then they won't work

ok well i dont have any wire going to the one next to the firewall, so do you have schematic on it or a pic on where the wire goes and comes from.

[suprra_girl]

i don't know of a pic offhand

but try looking under your intake manifold where your plugs go to your starter, transmission/manual wires and you should see another wire thats sorta seethrough, that should be connected to your knock sensor, more than likely it's broken off at the rubber bung

there is a tech tip on the sogi website for repairing knock sensors

maybe someone knows the link offhand

ok man, i got ur solution. i had my teacher look it up. hes an ase tech. ok what me and u have is a code 52, kjnock sensors are f*cked up. what it is thought, is the coaxial cable, the lines running from the knock sensor to wherever, i think the wiring harness/ecu..i dk. anyways, they way u fix it is u need ot replace these wires. toyota wants u to buy a new wiring harness for 2500$, butttt. go to radioshack and buy microphone wire cord, its the same wire with shielding aroudn it. u have to very carefull cut the wire at the knock sensor and wherever it is ending at. and then solder the new wire on. ahh i feel smart lol
