I have the same problem on a 1.2 16 valve mk2 ph2 extreme 4. Ive cleaned the sensor and the connectors. I stalled it today and it came on. Electrical fault light and then engine light and limp mode. Thinking its the connection points of the wires in the connectors. Shall try that ecu and fuse plug points. Does anyone know where to get a new accelerator to throttle body cable with ends?
