Check the back of the Ignition Switch to make sure the electrical part of the Ignition switch is not loose as the retaining screw tends to loosen off.

Is the check engine light on and have you checked for trouble codes yet ?

Engine code 25 26


man there is a lot of chatter about those codes and O2 sensors. I do know my truck popped a couple of those error. It ran rough and generally made my truck upset. I finally ran it down to the dealer and they said it was a broken spark plug. This happens to me in the winter. Run it by a dealer, but first pop the hood, start the engine have a friend rev the engine a couple times and see if you see an odd light from a spark plug or two. Best if this is done at night. Just be very careful not to reach in while the engine is running. Just watch. If you see the blue light, kil the engine replace that spark plug and retest. You can read here what some other tried:

If the crank sensor is failing, you should get a check engine light and a trouble code for it.

Coding a 2106 and a 2135 on 2006 Ford Expedition. Replaced the Throttle monitor sensor and cleaned the throttle body. Drove car and it ran good but next time it did the same thing. Engine failsafe and...


You need to determine if the ETC Failsafe is from a
bad throttle body motor (TACM) or coil misfires that are
putting it into failsafe.

The TPS Sensor you replaced,wasn't likely the issue.

Ran out of gas recently. when refueled and started again,check engine symbol stayed on? well mainted and has always ran great since new.


Sometimes the check engine light will come on if the fuel cap is not on tight enough. Check the fuel cap for an intact seal and install at correct tightness.

A major auto parts store will read out the stored trouble code in the car's computer for free. If the code pertains to the fuel EVAP system, the code probably set because you ran out of gas. Copy down the code and then have it erased. The check engine light should go out. If it comes on again, have the code read and the problem checked out.

Did you have engine trouble codes checked? Parts stores will do it for free. Ask them to explain what the codes mean, and what they recommend. If you have any questions, post them here with the code #'s. The engine light can come on if the gas cap is loose, but after securing, should go off. How is the cars performance? Running ok, just engine light coming on?

Make sure you installed the correct TP sensor. If so you may have a bad one. I have gotten bad "new" parts before. If all your problems started with the installed part start there.

1997 buick lesabre, engine light stays on


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!
