Codes and this sensor thing came up?
I no nowt I very stressed upset and could
Do with a kind person to send me instructions
Xxx I can give my number and email?

The crank sensor is on the left hand side rear of the engine (passengers side RHD) The electrical connector can be seen attached to a bracket just inside of the exhaust manifold looking from the top, (rear corner of l/h cylinder head) the connector slides out of the bracket and comes apart once the latch on the plug is depressed...

You will need to get under the car to access the sensor, the cover is held in place with 2 x 7mm nuts then there are two more nuts holding the sensor and spacer onto the rear of the block...re fit in reverse order to dismantling and check spacer they can sometimes be deformed or cracked if over tightend... (Just for referance, if you cant see the sensor, find the starter motor then look on the opposite side of the engine)...

Hope this helps...

Dont assume its the sensor gone down. It may have a faulty connection broken wire or corrosion at the ECU connection. Check all these things before spending on new parts.
