Engine management light
Hi all i have just recently bought a 3 door 87 E Sierra Cosworth took her out tonight and the management light came on so headed straight home even though the car was running normal.
Got home restarted the car and no management light came on drove her for 10 minutes without any problems can anyone explain why this happened?
Cheers
Paul

It means an input went out of range, so a loose connection, or a bad sensor.
The faults in the case of the Cosworth are 'volatile', i.e. when power is removed from the ECU, the faults are cleared, hence why you no longer have the EML illuminated, until it happens again.
