26 is a quad driver failure, 41 is a cam sensor failure. I can give you a test procedure for 26 but for 41 you likely need to replace the magnet that is in the cam gear for the cam sensor pick-up.

you can take of the ground of the battery of the car for 30 minutes and the computer will reset. if you drive around without reseting the computer might figure it out after 30 miles.

SOURCE: 89 buick lesabre electric cooling fans

You are off to a good start by testing the fans. Get a repair manual from your nearest autoparts store. I find them invaluable. Most temperature sensors can be tested with an Ohm meter. Or short the two wires together to trigger fans. If it has only one wire then ground it to the frame/body (negative side of battery). If none of that works (with ignition on / car off) then relay is bad. Also turning on the A/C should make the fans come on. Car does not have to be running, key in on position. This would eliminate bad relays or not.

How to troubleshoot air fuel mixture problem on 1989 lesabre


If your car has a MAF sensor, it is in the air intake hose between the intake and the air filter.
If the check engine light is on, you would need a scanner to read the computer data coming from the sensors to diagnose the problem.

Map senser location on a 1990 BUICK LESABRE


The sensor is a screen-looking device...located at the input to the fuel injection port. Follow the large air hose from the air filter...it should be easy to see once that end of the hose is disconnected.
Try cleaning it before replacing it...I use carb cleaner (generous spray of it directly on the screen). Then reset the Check Engine light (AutoZone can read and reset for you free).

Engine light on and it sputters when car inclines.


sound like the mass air flow sensor is dirty. take it off and clean with mass air flow cleaner and let it dry before putting it back in and try. it should be located in the air intake hose or the throttle body. also could be map sensor.

1988 buick la sabre trouble codes


code 23 is mat sensor signal low wich is the manifold temperatur sensor return valtage is low to the computer. check for a sensor that is on the air cleaner housing that has two wires on it. the connector on the sensor is grey in color. if it's not unplugged replace it.
the code 34 is for the map sensor wich is located on top of the engine. but if you have a bad map sensor you would be writing in for a rough running car or something.
was someone unplugging stuf when this thing was running at one time? - good luck
