and thought oh F£$K I have forgot to plug something in. What plug is this for? the subaru wiring diagram lists it as a pressure sensor its a three pin grey square plug yu can see it in the middle of pic but everything around the solenoid area is plugged in, there is nothing I can see around the engine that side that I have missed and the CEL is intermittent on/off, I have driven the car and I do get turbo shutoff at about 4500rpm so something is wrong, there are no splits in any of the vac hoses and all loook to be plumbed in correctly, I swapped the decat exhaust back to a cat exhaust for mot would this cause the CEL?

To be honest I am stuck although pretty quick at engine swaps is clear I have made a mistake but cant really afford to see a specialist (although the men in white coats are hiding around the corner!)

thanks

 

Lambda sensor?

 

looks like a lambda sensor plug to me to

 

thanks chaps will have a look in the daylight! I thought my lambda sensor was the white cylinder which is plugged in, whereabouts should the grey plug be plugged in?

 

i think that plug is to the (cat on fire) senscor ive decated my 96 import and left that un pluged wont make any difference (just means when the original cat was on its getting very hot )

 

on mine the white plug with the steel overbrade is the cat on fire and the grey plug is the lambda sensor that is on the headers
