I have discovered my detonation sensor is dead!

    Hi all,

    Well, again I have found more things to repair - why can't they be some small ones for a change? Error Code 34 - detonation sensor circuit. The testing I have completed verifies that the wiring to the E.C.U. is good and no circuit for the detonation sensor (read open circuit). - bugger.

    Anyway, I have read a lot of the previous posts and the bypass method from Twin Turbo forum/our tech area and was wondering what the latest thoughts were on the 'alternative' placement of a new detonation somewhere on the engine block? Or should I just bypass it for now, bearing in mind it will be 'some' time before I get excited and dismantle the engine to get to the detonation sensor!

    Cheers, Kaz

    IMHO, bypassing is fine. Most aftermarket tuners of the stock ecu run the same safety maps as the normal ones, with identical timing, and with a boost controller, totally negate the detonation sensor.

    Relocating is another good option. Depends on what work you are getting done, it may be worth replacing the det sensor.
     
  3. Unplug the old one and relocate your new one to the top of your motor.

    At least until your next engine rebuild when you can get rid of the old one entirely. I would not run without a det sensor. :cool:

    There are a couple of spots you can bolt one to at the rear of the ODS head. It's not correct that you don't need one with an a/market ECU. I know the Link ECU still reads the det. sensor.I should imagine that most would still want to reduce power when sensing detonation. When you do a re-build or 100k service and remove the lower intake manifold you can cut off the EGR mount which then gives future access to the det sensor(you would replace it anyway). Here's a before and after pic. Thats also a good pic of where the oil leaks usually come from .The two half moon seals and the EX cam covers
