I know I need a 1m ohm resistor for the bypass but which one do I need?

1M, that is 1 meg ohm, the others are denominations, like 3M5 is 3.5 meg ohms...

As my mini loom from dett. sensor to ECU loom connector was knackered, I cut off the plug, unclipped the top, soldered in my resistor the clipped the top back on, that way you are just left with a plug with the resistor in it, just plug it into the ECU loom, looks nice and neat...

Went into the shop but they had 2 the chosse from a 0.6w and a 2w. Which is the right on to put in? Leaning towards to 2w as it is larger but wanted to check to be on the safe side

try find the watt value of the dett sensor which its going to replace...i think it would be 0.6w

Either one will do, So long as you have got 1 meg ohm resistance you will be fine.

I think the .6w and 2w respectively is showing the level of wattage they can handle.

cool had a look in old threads and both seem to be used and as they were only 30p each was easier to buy both and find out later

Read somewhere that fitting a EBC would also bypass the det sensor, is this better as a more permanent fix?

if your fitted EBC Directly to the turbos and by passing the safety valves then yes ... but its still recommended that u use the det sensor and keep the safety valves in the the vac system with the EBC

Been out to fit the resistor and it looks like the black cable coming out of the plug has been cut!

 

 

Is this what is likely to be causing my code 34 rather than the sensor itself?

nope thats Normal ...

 

only the white wire is connected it takes its Earth from the engine its self ( bolt ) ..

 

just do your resister bypass on the main Loom side on both black/white wire

Have done that, just to check the resistor goes onto the male side of the plug?

resistor goes on the Main loom side

That's the side I put it on but is also the side with the cut wire so by the look of it i'm making a full circuit to nothing.

 

Taken it out for a test and still not going above 7.5 psi.

 

Should get my consult cable tomorrow so can plug it in and have a better view

The main loom side connector is the female one.......hope it solves your problem bud!

agree and just solder the resistor on to 2 spade conections and fit into the female plug...the "live" side of any loom is normaly a female socket so its protected from touching earth..htp.

thanx for the help guys will see how I go. Only going to be temp as I need to replace my tubs over winter so will fit a new senor and harness while I'm at it

Getting a bit confused I connected the resistor to the connecter that I have put the blue arrow on, but in the engine by numbers FAQ the det sensor is labeled as number 26.

 

Which one is correct?

 

does this make it more clear...

That's the FAQ that I was following but got confused when getting conflicting information.

only meant from the point of view of what connector to use ....

My DET sensor sits where the pexcom write up points to not the engine by numbers diagram. However it is possible to jumble thos rear connectors as I have previously plugged it into a VTC one on the loom mistakinly! Best way is to look at the wire colours on the main loom side connector

DET sensor should be a white and a black wire(earth shield). The VTC connectors should be a red/black and a green/black wire.

Cool then I have the right one.
