So i have got this problem at the moment with the engine light i plugged in my laptop and read the error codes it come up with CrankShaft Sensor & 02 Sensor i have now replaced both of these and the engine light still comes on and i still loose power and this happens at any speed after driving for about 10mins so i pluggged my laptop back in and it said 02 Sensor again so i took the 1 that was in their back and got a new 1 to replace it and the problem is still happening and the laptop is still saying 02 Sensor anyone got any ideas what could be the problem?

have you reset/deleted the fault codes?

I have unplugged the battery etc
I am going to a garage this Monday and getting the ECU reset properly.
Ill let you know how i get on

Can you not "Clear fault codes" with your reader. With the readers that plug into a laptop there should be this option somewhere along the line. On mine you clear the fault codes before reading the new ones otherwise it just adds to the list.

i had this problem with mine the code reader brought up the 02 sensor but it was my air maf meter that had gone this cost me £200 to get fixed at a main dealer but since getting it done 2 month ago the problem has not come back

How long have you left the battery disconected for ??? it needs a least 16 hours to reset the ecu.
