Engine Management Light On After Tyre Change.

[Scotsman]

Posted this question in the Corolla forum but guess it should be here.

I've a Corolla 2.0 D-4D T3 on a 53 plate.

Three weeks ago the back wheels were taken off for some brake work. When the engine was started after the work was done the engine management light came on. The garage read the code as cam sensor. They reset it and the car has been fine since.

Yesterday I took the car for new tyres. Again when the work was over and the car started, the engine management light came on. I pulled the ecu fuse for 30 secs and that cleared it.

Mr T wants £90 to hook it up for diagnostics :o

Any ideas what's causing it. The only time it happens is when it's jacked and the wheels messed with. Its never came on when driving or any other time.
