What size engine?

If it's rear wheel drive the the MAP sensor is located on passenger side by the throttle body it's a little black box with three wires and a vaccum line connected to it.

If it's front wheel drive, then the map sensor should be behind the throttle body close to the firewall on the passenger side.same discription

SOURCE: 93 buick century -turn signals

The Buick Century uses separate relays for the hazard warning and turn signal functions. The turn signal relay is located on the accelerator pedal bracket, and the 4-way flasher relay is located on the convenience center near the left kick panel. Try switching these two relays with one another to see if your turn signals work instead of your 4-ways.

SOURCE: need unlock code for 2003 buick century car radio

You will need to take the car to a dealership to have the service department unlock the radio for you. They have a special code to unlock the radio and then you are required to change the code to one that you will remember. An appointment should not be needed because this takes about 5 minutes. I do not remember the code, sorry.

2003 Buick Century just quits running going down the road. Keeps throwing a code for the MAF sensor. We have replaced this several times. It will run fine for a couple months then it does it again.

Why would you think the issue is with the MAF, did you do the diagnostic testing? What was the fault code? MAF sensors seldom fail. I would look for loss of fuel pressure or spark maybe. I think the MAF fault is due to the other problem and it is not the cause of it but a symptom.

What is the meaning of troubleshoot codes 34 and 45 for a 1988 buick regal, 2.8 motor. how can I fix them.

Code 34 is MAF sensor out of range. Code 45 is O2 sensor lean. Check the voltage at the wires to the MAF sensor first, then check the vacuum to the sensor. Your MAF sensor has probably gone out, causing the O2 sensor to fault.
Hope this helps, you will need a digital volt meter and a vacuum gauge to test. I have seen the wires break down in the insulation to cause fault.

Code 34 MAF/MAP Sensor Circuit Causes? Light stays on.

One thing you can do is unplug the MAF sensor and then start the car and see if anything changes. If it runs better and does not stall, its possible the MAF is completely bad and needs to be replaced.
