Car wont start - oil on connector thingy!!

[DAMO 40/172]

Hi

Car wont start again. Had this prob a few times now. Oil/liquid seems to be getting in to the connection pictured below. if cleaned and dried car starts again. Problem is it keeps happening and i dont know why. Anyone offer any help and advise?

Can you not see where the leak is?

Try wrapping the connector in something for the mean time.

Id say switch is knackered mate, and leaking through onto the plug at a guess

Is that not the power steering sensor?

Yes, Mines full of oil too

the pas sensor wouldnt not stop it from starting.

any lights on the dash?

Was going to say lol

no warning lights at all, car turns over but just wont start. if i get all the oil off it works but i cant stop the sodding oil coming back. the connector goes in to some sort of solid metal pipe at one and and them the lose wired cable connector plugs in to that.

It's the pas pressure sensor. If it's leaking ps fluid, then it will need replacing. Although I'm pretty sure as said that it won't affect the starting of the engine at all.

sod knows then. if i clean it up the car starts.

Well I'm pretty sure you can run the car with the sensor disconnected. Had one fail on my 172 years back. Where is the oil coming from?

Fault with the immobiliser/key? Does the red flashing light on the dash go out when you put the key in and turn it to stage 1? Mine was well on its way out, sometimes the light would go out, othertimes the light wouldn't, in the end had to get a new plip/fob key.. Have a check, as for the sensor I'm sure the PAS pressure connection would have little to do with the starting of the car..

looks like from the metal pipe. outside was caked in black looking oil residue. inside looks like a very pale looking oil substance.

incase you havent guessed i know sod all about cars!

If you can't start the car and clean the PAS connector up and the car starts that seems to be the issue - get the leaking bits replaced. But what happens when it's cleaned and you disconnect it again - will the car start?

Might be putting a short onto something that doesn't like it and dragging an ecu voltage down hence it not starting. As the actual switch input "doesn't" do anything apparently.

I'd go for changing the pressure switch itself as previously mentions as i'd imagine its leaking through it as said. PAS fluid will probs want topping up after if you loose a lot, worth checking anyway.

What does the sensor actually do, Mine kept unplugging itself and nothing came up on the dash or felt different

Mines been cut off and the car is fine without it. Doesn't affect it if its unplugged, but as said if its shorting something on the ECU when plugged in that may do.
