one after another
 

well i just fixed code 11 and know im looking to find out how to fix code 52. i know its the knock sensor control. my question is were is it located and how to fix it. "pic would be nice"

88 turbo.

thanks for all your help hopefully this could be the last thing that i need to take the check engine light off and i can get it registered and get this car on the road.

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

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????????

if anyone can help i really need some help on this so if theres somthing im missing let me know plz.

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.

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
