If there is no spark then it possible you have lost signal from either crank/cam sensor/ id say check the crank sensor first as normally thats where the ecu take readings from,as per crank position to provide spark/ dont mention year/nor engine size etc..have you double checked the timing belt just to be sure...however if your fault warning light is on..then id suggest before making any replacement with those sensors is to see what fault codes you have stored in the ecu,plug the car in to get those codes.any good mechanic would do that first.hence why the warning is thats one possible cause/step forward from here..I do hope this helps

Vauxhall Corsa-C 1.2L. Where is this sensor located ?

Expert:  Robert replied 2 years ago.


They actually locate these in differing areas to be honest..but the best place to check on the 1.2 is on the lower edge of the engine block / back of the engine..near the drivers side inner cv joint as it enters the box..look on the engine block and you should see the sensor/3pin multi plug..and the sensor held to the block with a single torx the impulse ring the sensor reads is inside the engine on the crank..if you don't see it there..then inspect the crank pulley as you look in from the drivers side wheel wheel and see if the sensor is on the left hand side of the crank'll know the sensors on that side if the crank pulley has the target/impulse ring on that...
