its nasty aint it, i only have code 47 atm lol.

the knock sensor is a device that senses knock in the engine or 'pre ingnition' (pinking) it allows the engine to run as close to the point of knock as possible, this helps the engine to run more efficiently and gives better power.
if your ecu isnt showink a fault code for the knock sensor then its not likely to be this.
(its bolted into the back of the block btw)

if uve already changed the crank sensor and cam sensor, then i would put a set of clocks with a vss in. i remember on migweb, there ids a way to fit the gte clocks and still get a vss signal. look on there.

did u clear the ecu when u had changed the sensors?

what is the knock sensor? and where is it?

most corsas have imobilisers from the factory....key has a transponder in it

i had similar faul codes once, the fault for the fuel pump relay can be caused by another sensor showing a fault. with mine the knock sensor had a problem. once i changed that, the codes for fuel pump relay and immobilisor wrong code dissapeared.:D

Look at these problems,

12 - Initiation of diagnosis.

85 - Immobiliser - Wrong signal

84 - Immobiliser - No signal

29 - Fuel pump relay

92 - Camshaft sensor - Faulty hall effect sensor or circuit

73 -

19 - Crank Angle Sensor (CAS) - Incorrect RPM signal

24 - Vehicle Speed Sensor (VSS) - No speed signal or low voltage


My car keeps cutting out :( and these problems, i have changed these -

92 - Camshaft sensor - Faulty hall effect sensor or circuit

19 - Crank Angle Sensor (CAS) - Incorrect RPM signal

i havnt got an immobiliser, so what could that be, could i take a fuse out or somthing? and the VSS is that because i have an astra GTE one in?, what about the fuel relay? please help!!!
