SOURCE: 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

This is a fairly common problem, Gm has actually issued a service bulletin regarding this repair. The problem probably originates from one of your wheel speed sensors that is mounted inside one of your front wheel bearings. To be sure, you need to have the car scanned to find out which one and then you have to replace the whole bearing assembly because the sensor is integral to the bearing. The bearing is not hard to do but you will need some professional tools if you want to do it yourself. At a shop it should cost between 3 and 400 dollars complete.

2002 BUICK LESABRE LIMITED,VIN K. FUEL PRESSURE IS 44,SHOULD BE 53-59.I HAVE A PO171 CODE.IS 9PSI IN FUEL PRESSURE ENOUGH TO CAUSE THIS CODE? I HAVE CHECK FOR AIR AND VACCUM LEAKS,NONE FOUND


You need professional tools to solve that

If your checking for leaks, means a visual inspection,
then you not going to find them,you need an Evap
Smoke Machine to find Vacuum Leaks quickly

A worn out Oxygen Sensor could be the PO171 code

Have to look at scan tool data,fuel trim,fuel pressure,cylinder misfires, consider a bad exhaust converter,many things to test,you can't do in your driveway.

Some vehicles have a computer controlled fuel pump,
so you need to know the strategy there, before that alone
is an issue.

1997 buick lasabra engine code >po171


The trouble code is related to a lean engine fuel trim problem. This particular code can be caused by a vacuum leak, low fuel pressure or faulty MAF or MAP. Check for vacuum leaks first, if you cant find any broken or cracked hoses, you might want to take it to a good shop and have live data read to determine if there is a component defective.

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!
