    I'm getting this code, I've researched what it is, how to fix it etc.

    Just a couple of questions i can't find the answer to.
    How risky is it to bypass? What difference will bypassing it make? Should i be driving it with the DS faulty?

    The multimeter is measuring about 450 on the ECU positive. Shouldn't it be closer to 500?
    Measures with the car off, But I'm not a mechanic nor am i a auto electrician.
    My multimeter is set on
    V-... 2000m
    is that the right setting?

    My car is using allot of fuel (around 360km to a tank) and its throttle response is not perfect, also stalls sometimes from idol to accelerating.

    I would assume that this wouldn't be the solution to those problems but its one at a time for the moment and this is the first.

    Its an N/A Auto.

    Shouldn't be too dangerous for NAs. I'd make sure I'm running highest octane fuel available though. Bypassing will take it out of rich maps, giving better fuel economy + more power.

    you can check out my post on det sensor man i was having some trouble and tuned out to be faulty wiers so i did the usual cut and soldered and have not had the code since .. you might want to follow the cables and see if there is any dodgy bits ... .. from what i understand the resistor just tricks the ecu to think then dett sensor is in working order and that you have no "knock .. .. it sounds to be quite fine but id mutch rather not do it just incase you truly are detonating cause your engine will not last long at all .. :zlove: so check cables clean connectors etc etc if it doesnt help then your sensor may well be screwed ... also just to add to my ramblings .. if you do a "bypass" and your fault is on the ecu side .. it wont do **** and you have been hacking wiers for nothing lol ....

    Sorry, but why did you need to actually cut them? Couldn't you just add solder to add to thinkness of them? (if they are flimsy)

    Reason I ask is i'm getting code 34 also, and also looks like my wiring is a little shitty near the plug. I was going to just strip the wiring and add some solder so it's a bit thicker..

    i only cut and put new wire because mine has been soldered already once defore and from where there was no insulation just elect tape the wires has gone all oxidized all green and useless so i just though to save the headache put new ones in lol ... but yeah solder should!!!! work if there are no other factors except breaking wier :)

    wiring is fine. Multimeter is getting about 450 from the connection, is this an ok result? or is my wiring actually not fine...
