The engine check light has come on.
Holden astra ts Z18XE engine.
diagnostics said it is the crank angle sensor.
I have replaced the crank angle and the camshaft sensors with genuine parts.
Following that the code was entered and the check light went off and the car was going great.
when I got home turned the car off, then started back up and the check light came back on.
Same again did the codes light went off all good. After turning engine off and then on light is back on an running as if timing is out or running on 3 cylinders.
What can I do to fix the problem.
is there a way of testing the sensors.
Is there certain voltage these sensors must recieve
is there a certain amount of ohms or whatever signal they send back to the computer.
your help will be appreciated so much
Thanks kindly
Paul

Don't worry about the donation. Listen, we are in north America and we don't have these vehicle and my manuals don't list them. So, as far as the specifics regarding checking the sensor, I don't have. Can it be done, yes.

Regardless, it doesn't sound like the sensor is the issue. To me, it sounds like there is a wiring problem since it works correctly sometimes and not the others. Is that the only code that was found? Also, have you checked to make sure the wiring to the sensor is in good condition and there is no corrosion on the plug or if the plug doesn't fit properly?
