GM OBD Trouble Code 44

Auto Systems and Repair

Oxygen Sensor Error (Lean Condition Indicated) The ECM receives a signal from the O2 sensor based on the amount of oxygen in the exhaust. If there is excess oxygen in the exhaust, it is in lean condition and the O2 sensor voltage will be low. The ECM uses this information to adjust the amount of fuel delivered to each cylinder.
Fault Code Description
  • 44 - Oxygen sensor error (lean condition indicated)
  • On V-type engines with two O2 sensors, code 44 would indicate the left bank sensor is lean
Symptoms
  • Lack of power
Common Problems
  • Faulty O2 sensor
  • Engine vacuum leak

If your car runs bad with an EGR code then I would suggest that the EGR valve be replaced. I would like to know what code was set on your computer. It would help greatly. When the EGR malfunctions, you will have rough idle and possible stalling. If you have a code indicating EGR it may also condem the cat converter.Please show any codes that are set. Thanks Moe

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.

SOURCE: i have a 1998 buick century limtied

I would suggest buying a Haynes/Chilton book for both models, they may even be one in the same if the years are close enough. Look up the schematics for both and compare the differences circuit by circuit. There may be some slight differences with connection fittings, but thoroughly review the schematic diagrams first.

When my buick century 1995 is cold it will start but won't rev up. once it is hot it runs okay


Number of possibilities. See if you have any diagnostic codes stored. Could be throttle position sensor, coolant temp. sensor, hard to say. I would start with the codes. Does it start easy when warmed up, and run good? Boy, I just don't know.
