List of error codes from www.mytuscan.co.uk

•A - Speedo sensor not activating zero switch
•B - Speedo sensor not releasing zero switch
•C - Water level sensor not activating zero switch
•D - Water level sensor not releasing zero switch
•E - Fuel level sensor not activating zero switch
•F - Fuel level sensor not releasing zero switch
•G - Water level sensor open circuit
•H - Air temp sensor open circuit
•I - Oil temp sensor open circuit
•J - Oil pressure sensor open circuit
•K - Fuel level sensor open circuit
•L - Erratic road speed sensor input
•O - No communications between analogue and control

I would check the multi-pin connector to the sender unit on top of the petrol tank under the flap. Give the plug and socket a spray with contact cleaner, and try the ignition again. Usually sorts the problem.

Try disconnecting the plug on top of the fuel level sensor. Level should drop to zero and you'll get an empty tank error. This should narrow it down to the sensor.

Apparently the sensors are quite problematic but it's not an expensive item. If you need a new one, get a new gasket at the same time.

Wow...thank you for such a rapid response guys!

Brilliant. The minute it stops bloody raining I'll get outside.

Again, cheers chaps.



as a newbie, is this petrol tank easy to get at to see the sender?

There is a flap that goes all the way across the top of the fuel tank, this lifts up and the fuel level sender is on the right hand side.
