It will make more problems than help if you just plug the o2 holes in the exhuast and tie the o2 sensor to the frame rail, drive it and see it it tosses any codes if it does, you can use a simm for your 1989 Dodge. I hope this helps.BENZ STAR C3

SOURCE: how to replace a coolant level sensor, 2000 buick century

The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

I need to know the code dtc44 for a 1990 Buick Century

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
  • Lack of power
Common Problems
  • Faulty O2 sensor
  • Engine vacuum leak

Where is the oxygen sensor

It's on the rear exhaust manifold. You will need a oxygen sensor socket to remove it. If you are not saving it & tend to replace it, snip wires & use a normal socket. Saves the price of the special socket! Good luck!

I have a 1983 buick century I was told it needed

the o2 sensor is usually on the exhaust manifold, or int pipes that lead to the catalytic convertor. It sniffs the summed exhaust gasses from the engine, so look for it in the plumbing AFTER the headers.manifold comes together into one pipe.
It is a threaded sensor about the size of a spark plug.
