Having problems with your Saturn Ion ?

Computer showed that we have to change crankshaft position sensor in a 2005 Saturn Ion , we did it but the check engine light is still on. How to do a reset to make the check engine light go off?

Answers :

You can take the negative terminal off the battery and let it sit for at least 15 min, then reconnect and turn the key on and wait for the diagnostics to turn the lights off, then turn the key on and let the computer re-learn its idle pattern and such, this should clear it if you have repaired the defect. If it doesn't clear then the repair wasn't correct or not installed correctly and needs furthur attention.
The check engine light can only be reset by having the trouble codes in the computer cleared. The codes must be cleared using a scanner. If there is a Auto Zone part store near you, they will hook a scanner to your vehicle for free. Once they do the scan, they can then clear the codes with the scanner.
