Cam and crank sensors
In the future, I wish to perform oil and filter changes myself on my 1993 WRX 4-door... Can anyone tell/show me where to locate the cam and crank sensors and how to disconnect them on this model, etc...
|
the crank sensor is more or less in the middle of the engine below the alternator just aboe where the plastic cam covers are. The cam sensor I think is on the top left hand side of the cam cover so that will be the right hand side if you look at it from the front of the car.

You need to disconect only the cam sensor, front right side of motor by oil filler cap.

So *Un-ink*, just to be certain, if I disconnect ONLY the cam sensor, I definetely WON'T cause the plugs to spark when priming the oil pump after an oil change, yes? |
yep plugs wont spark without sensor connected
|
Am I barking up the right tree?...

They are the right sensors, but undoing the nuts will actually loosen/remove the sensors themselves. They should have an electrical plug that can be prised off.

Disconect Just the cam sensor you will be fine.

Please describe the removal procedure/technique, etc... Thanks, John. |
With the nuts undone both sensors just pull out of the block (sensors are a round metal cyclinder with plastic electrical connector on top) leaving a round hole in the block into which they slot back easily. On the electrical connector there is a slot - ease a flat head screwdriver in there gently and pull sensor away from cable - easy.
The cam and crank sensors are a doddle to disconnect Changed my crank sensor recently when it failed - five minute job if you have a suitable size spanner which can get to nut behind alternator. |
Yours are the early sensors, you need to chase the wires back and disconnect from there. I have read before that the crank sensor is the one that is used whilst cranking, and the cam when the engine has fired
Hence it won't start of the crank sensor is faulty. |
does anyone know how to teach my subaru to run on 95 octane i ave heard from a few people you can,i dont know..

It's a multiplug, all you need to do is follow the wires back and you will see where they connect
Have a look and you will see what I mean. Adam |

Have a look and you will see what I mean. Adam I traced it back and it appears to be a grey multiplug that sits directly underneath the short I.C.-to-plenum chamber hose. Is this correct? Thing is, it looks a pig to try to prise the male and female connectors apart - would I need to temporarily remove the hose to do so? Or can it be done with the hose in situ? If so, what's the technique? |
