you can have the engine running or not, it doesn't matter.

the engine light is on

[Holden202T]

the engine light will be on when the engine is not running but the ignition is on

[holden08]

yea it stays lit when the engine i running

[Holden202T]

well a log will give you the answer to that aswell in the malfunction flags section.

engine light is possibly if you have not changed knock sensor back to the early style

[Jayme]

the engine light is just coz of the coolant temp sensor. have you swapped the sensor to buick cts? they are different.

[holden08]

changed the knock sensor i changed the temp sensor the one that has to wires

[Holden202T]

well if you have the right sensor in there you might have a wiring issue..... also i've seen the plugs sometimes get a bit dodgy and the pins push out the back of it when you connect it to the sensor.
