SOURCE: My dodge dakota wont idle,foules up plug

check the gasket for the bottom of the intake plenum
to check remove pcv valve from the valve cover plug the vent hose from the other valve cover and the hole the pcv valve was removed from with your fingers while the engine is idleing. if it builds up a vacuum, noticable by a air rush sound when you remove finger from vent/pcv grommet hole then the gasket for the plate on the bottom of the intake plenum has blown out. it is a very common problem and results in fould plugs and oil consumption problems.

You could replace the sensor yourself but you'd need a diognostic computer to clear the error codes from your car's ecm or you'll continue to have the problem even after you replace the sensor. A lot of the mobile mechanics have these diognostic computers with their tools.

I am pretty sure each O2 Sensor has it's own code.
If you have the code scanned again, it will tell you which one it is, bank 1 or bank 2 . before or after the Cat.

Code says left upper catalyst insufficient. What does this require to correct? 2000 Dakota 5.9 360 ci.

Possible bad converter. however I would replace the rear o2 sensor for the bank in question. IF the converter is the problem, the o2 sensor will need replacement anyway. In most cases the sensor will correct the problem

You will have a total of 4 O2 sensors, two on the left (driver's side-Bank 1) and two on the right (passenger side - Bank 2). Sensor 1 is before cat. convertor and sensor 2 after cat. converter. Hope this helps.

Need to pass emissions test, dianostic test - Catalyst efficiency blow threshold (bank 1) tried to order part - now I need to know if it pre or post, left or right Oxygen sensor, can it be determined by...

Yes it can be determined by the DTC (Data Trouble code). If the DTC is P0420 (catalyst system efficiency below threshold Bank-1) then the side of the engine with the #1 spark plug and cylinder is always Bank-1, and the O2 sensor that monitors the catalyst efficiency is usually after or (post) of the catalytic converter.

The #1 cylinder is located at the front spark plug on the right or the passenger side of the vehicle, so Bank-1 is on the right side of the vehicle, and the O2 sensor that monitors the catalyst efficiency should be located after or (post) of the catalytic converter. It would be the post right O2 sensor.

There is also the possibility that the catalytic converter is actually starting to fail, and if changing the O2 sensor and clearing the DTC does not solve the problem them the catalytic converter is most likely faulty.

How do I locate the o2 sensors on a 2001 Dakota w/ a 4.7 ltr Magnum & automatic trans?

O2 sensors are located right on the exhaust pipes. If it is an upstream sensor it is before the catalytic converter. There can be one on each side of the motor. If it is a downstream sensor it is located after the catalytic converter.

My dodge Dakota has a bad o2 sensor on it. It has 4 of these sensors, 2 on each side. How do I determine which one is bad?I did have the check engine code read on it so I do know it is an O2 sensor.

I am pretty sure each O2 Sensor has it's own code.
If you have the code scanned again, it will tell you which one it is, bank 1 or bank 2 . before or after the Cat.
