vauxhall vectra 1.8 16v petrol?

1.8 eco probably cam sensor...25 quid off Ebay??

try the below to read "blink codes" off ecu light.

No warranty given or implied by doing this...works on most vxl/opel cars

The following chapters are taken from the How To on www.topbuzz.co.uk (http://www.topbuzz.co.uk/)

The Simtec 56.5 fuel systems use a 4 digit flash code. The engine ideally needs to be running when reading the fault codes, otherwise it may show incorrect fault codes.

Once the wire link is in place and the engine is running, the ECU warning lamp will begin to flash out the codes (wait for the initial boot up check that lights up all the warning lamps). Each fault code is repeated 3 times and then it moves onto the next one (if any). Once at the end of the logged fault code list, it will go to the beginning again, giving you plenty of time to note down the code (on each fault code shown, there will be a pause before it shows the next one). It will carry on like this for ever until you remove the key from the ignition or the battery runs flat. To clear the codes simply turn on and off the ignition 30 times with a 5 second 'on' gap in-between (time allowed for self check to finish).

For example, lets say there was a ECU warning lamp noted and the owner wanted to read what fault code was logged. The owner has already put the wire link in place and switched on the ignition. A flash is indicated by an astrix (*) and a pause is shown as a dash (-).

Note that 10 flashes = number 0.

**********-*-*-***** (10 flashs, 1 pause, 1 flash, 1 pause , 1 flash, 1 pause and 5 flashes = P code 0115)
**********-*-*-***** (0115)
