Knock Sensor

[Dan Evans]

i just re-set it, if it was bad it would of stayed on the system, i think i may have over boosted at some stage which cause it to go on, I've turned the actuator down and im going to give it a go tomorrow.

[micky boy]

Sweet im glad it wasnt nothing to bad :harhar:

ps the blitz ecu is still unreal ;)

[Dan Evans]

lol. its now on my mind, i wanted to buy new plugs,leads,cap and arm, BUT now you have offered this im unsure what to do??

i dont know weather to bother because of the 5E, or do i get it and enjoy it for the rest of the year??

[micky boy]

Lol buy it and enjoy it for the rest of the year :harhar: class it as in investment you can sell the blitz ecu come next year lol then you will have the money ready for when you need a new ecu ;)

[Dan Evans]

Right, its back on again now, would it come on if say the FMIC pipes knock against the gearbox or something??? or is it an internal problem???

if someone could shed some light please

cheers

knock sensors are quite delicate, it might be the case that it's a bit intermittent. so you reset and it's ok... you hit boost and it goes crazy again and puts the ecu into safe mode.

they can play up when ever, remember they are probably the original so pretty old. mine went in my old V. might just be good to replace it and see how it goes.

[Dan Evans]

ok mate, im going to make sure no pipework is tapping the gearbox/engine give that ago, if not then il replace the knock sensor and see what happens. I've just been quoted £158 for a new one!!!

I have this same problem hit with 2,5k the engine light.. and it's code 52 to..

And have got the save mode now for 3 or 4 times.. then it runs like shit.. and on my wideband it runs rich.. like -10

And if i don't hold the thottle it will faul out

Please help..

check fuel presure and do a plug read to see which cylinder has detonation. i have had blocked fuel filters that have chased this problem.

[Jeroen W.]

There is noting wrong with the plugs.. and the stock fpr is on there..

Does anyone know what nm the knock sensor must be installed?

The wire on the knock sensor tends to get damaged easily, it has happened to my cars twice in the past. Is the wire on yours in good condition? It's the single wire on the left side of the inlet manifold that runs down.

lol i am with Idres on this, check the wiring on the knock sensor first (hes said 3 times to check!!), at the end of your fuel rail (on the left) its a single wire, it runs down to the sensor and is sat between your starter motor and alternator on the back of the engine.

Probably worth while, pulling the plug off, clean it, clean the terminals on the plug then put it back on,

I know what wire it is.. but how can i test it if it's good ?

With a Multimeter?

And knows any one at what moment it need to be installed the knock sensor?
