The are many things that can cause your "check engine" light to stay on. One possibility is that although you have fixed the trouble code for your crankshaft position sensor, the code has not been erased from the computer's memory. Another possibility is that you have another issue going on that is causing a new trouble code to come up. You're going to need to have your car hooked up to a ODB-2 engine code reader to see what the issue is. These code readers are available for purchase at any auto parts store. In addition, many of your local auto parts stores will check trouble codes as a free service to customer. If not, many parts retailers offer the option to rent one of these code readers. Which ever way you decide to go, run a full engine/emissions trouble code check. If the only code that comes up is the code that came up previous to fixing your positioning sensor, then all you need to do is erase the trouble code from the computer's memory. (Most code readers have the option to erase trouble codes, but if you're going to rent or buy one, I would suggest that you check to make sure that the code reader that you're getting is capable of erasing trouble codes as some code readers only indicate the codes and will not remove them from your computer's memory.) If your trouble code scan reveals other codes, then you'll have to fix and erase them as they arise.

FYI- In my experience, I've noticed that 95% of the time that a check engine light/trouble code arises that it is usually an emissions problem (oxygen sensors, mass air-flow units, MAP sensors, etc.). However, General Motors products are notorious for getting trouble codes for having loose battery/ground connections and for having worn-out fuel caps. With any GM vehicle, I always check these two things first to try to save me from having to look further than I need to.

Hope this helps! I'm sure once you've scanned your cars computer and erased any existing trouble codes, that you'll stop being annoyed by your check engine light, as I know how bothersome it can be. Have a great day!

98 Buick LeSabre was running great, no problems at all. Leaving on trip, pulled out of the driveway, put car in drive and suddenly it started running rough and blew white smoke out the tailpipe. Engine will crank but will not start. All fluids are good. It won't start so can't get it to an Auto Zone for trouble codes. Any way to get them manally? Any assistance is appreciated.

Location of crank sensor on 1997 lesabre


The crank sensor should be on the passenger side of the engine. It probably won't be visible without first removing the power steering reservoir, and possibly other items on that side of the engine. It is located down below near the waterpump pulley.

Think my friend sounds like your alternator has gone bad on you... Your battery still holds power and enough to run your electronics and starter but not enough power to run your ignition components.

1995 Buick LeSabre - Stalls then restarts while driving


Has the fuel filter been chg. lately. If it has, maybe a fuel pressure test is in order. Fuel pump might be geeting weak and does not show up until it gets warmed up. Fuel pumps are a common problem on this type of cars.
