Having taken from the middle of january to the middle of May to replace my f@cked engine and turbos and then sort out various other problems Anglia Engine Services decided that the best thing to do when the engine then overheated was to send the car over to the suppliers of the engine, Nippon Spares, for them to replace it again and carry out the job. Compared to that prick at Anglia Engines Nippon have been very good, in a month they have replaced the engine, disconnected my heater matrix (perished pipe I cant afford to have that job done now), sorted out a water flow problem, sorted out a idle problem and everything was fine until engine check light comes on. They find the code and its knock sensor. Guess what? The bloody bleed valve that was on the car when I brought it and is probably the reason why my engine detonated and cracked two pistons and replacing with the standard actuator was gonna be the first thing (as well as the engine obviously) that Kerry at Anglia Engines was gonna do IS STILL ON THE CAR! The thing thats concerning me with Nippon Spares is that it was only when he told me about the Knock Sensor and I mentioned it used to have a bleed valve but it had been taken off that he realised that the bleed valve been on the car may be a problem. He said "yeh I noticed that little blue thing and thought it looked a bit dodgy"! Christ a bit dodgy, understatement! Well this was 10 days ago and he said he would get an actuator and replace the knock sensor (I thought why when surely its working fine becuase its doing its job if its sensing knocking but then I suppose if its a new one in there then we know if it tells us something then it will be accurate), well the parts were gonna be in friday and I have the car monday then they were due monday,then they would have it all ready wednesday and now it will be done friday - I am noticing a pattern developing here! I am going on holiday on Saturday and the bag of crap that I brought as a runabout is due an MOT next wednesday and Ive got more hope of Ronaldinho playing for England than there is of this car passing its MOT! As you can imagine I am just a tiny bit annoyed! Anyway, as the thread says as anyone dealt with Nippon Spares before just to put my mind at ease, because Im starting to feel like these are mucking me about as well.

The ECU has recorded a fault code for the Det sensor becuase the det sensor or its harness has failed. It does'nt record a fault for actual detting. The car will be in safety mode at the moment (Reduced boost, retarted timing).

 

Its usually a £300-£500 job to replace. Most usually just bypass it.

Think I got my replacement Engine off them which was transported down on the back of a low loader... They we're very quick to take my money and didn't even say thanks but it all arrived ok with just a few bits needed replacing off my old engine to make the new one complete and 400BHP later... At least they gave me a good 'un!! :D

our company avensis had work carried out by them and new engine, The took cash very fast , customer services was crap , took 4 weeks instead on 1 week they said and now the engine is making a funny noise and smoking !! id avoid mate like the plague.

Is this Nippon in Derby?

That's where I bought my Z from last week.

They seem genuine and they did everything they said they would do.

Matt is the best bloke to talk to.

Had a look round the stores, got a right load of stuff there. Didn't see much in the way of engine overhaul facilities tho.

i was talking about the london one.

i bought an AFM from nippon in london the part was ok but there delivery left alot to be desired. they said it was next day delivery but it took about a week! but at least it got my workin again.

So if it doesnt record faults for detonation / knocking then what does the det sensor actually do? When you say bypass, you mean not have det sensor a tall? But then if it doesnt record faults for detonation / knocking then I suppose I wouldnt be any worse off if it was bypassed.

to bypass the det sensor a 1 mega ohm resistor is bridged between the terminals of the engine loom plug of the det sensor harness.if you dont know what detonation sounds like i wouldnt advise you to do this as it will cause piston failure.usually the piston land between the scraper and compression ring breaks up causing blow by then its rebuild time again.i have heard of relocating the sensor to one of the inlet valley studs to save time and money but the ideal place is on the block between the two banks.

the det sensor is an engine protection device which senses detonation rattling then retards the timing and increases fuelling to prevent damage.without the sensor (dreaded code 34)the engine will stay in safety boost/timing retarded until it is rectified.

Basically yes the knock/det sensor does detect detonation and reports it back BUT when u have the code on the ecu 34 that means the actual sensor itself is faulty
