The ECU fault light on our 1994 cavalier (X20XEV engine) has been coming on frequently of late. When I diagnose it I find fault code 24, which according to a list I found on the internet translates to "Vehicle Speed Sensor - No signal".
Does anyone know where this sensor is located? There is a speed sensor on each wheel hub, but I suspect these are only used for ABS and that the engine ECU would have a separate one, but I can't find it! On my 2001 Astra, there is a speed sensor located on the gearbox, but I can't find one on the cavalier.
Can anyone help me?
many thanks, Paul.
