00513 - Engine Speed Sensor (G28)

[Leon27]

Aside from scoping it with the proper equpiment theres not much you can do except removing it and inspecting it or getting right under the car to have a good look.

Another test could be to find where the crank sensor wiring goes to from the plug picture you posted and find its earth/signal wire etc. Got a wiring diagram? Anyone! I'll see what I can come up with tmrw.

Cheers mate. I'm sure someone will know where it grounds to.

Have you checked to see if the Speed Sensor is loose. Its in a fiddly position behind the oil filter area and held in with an allen screw.

Also some ECU's throw this fault code up when you scan without the engine running.

If there is a fault I would expect the car to cut out or not start.

1 - red/yel - ecu pin 68
2 - green/blk - ecu pin 67
3 - brn/blu - earth, in engine wiring harness.

I believe the earth is on the back of the head, or internal to the wiring loom to the main battery -ve. if in doubt, bare some insulation from the wire and solder a fresh earth to it, run to ground somewhere good

Cheers Rubjonny! Mr. Khare, little tip, dont push something big into the hole of the ECU plug like a safety pin etc, try to match up a pin like on the ECU to test with, Ive had numerous come backs because some people have spread the contacts of the looms and when plugging it back in it doesnt make contact anymore.

Good advice by Paul as well, check that sensor is tight!

[Khare]

Nice tip guys, thanks. I'll make sure it's tight then I'll check the wiring

So I can just redirect the earth to a good ground anywhere on the engine and that would make a perfect earth?

[rubjonny]

yep
Thats how it should be anyway, the earth for the crank sensor runs back inside the loom and is joined to an earth wire which runs to the battery or head, cant remember which off hand. its on the same wire as the inlet temp sensor earth.

[Khare]

I see. Ok, well I will check the tightness of the sensor, then put a new earth from the plug to the head (do I have to chop the old earth or just tap into it?) and if it persists then new sensor time I guess.

[rubjonny]

I would tap into the earth rather than chop it
