Why is my O2 sensor on my KA24DE not working?

Why is my O2 sensor on my KA24DE not working?

Apparently the Front O2 Sensor dieing is a very common problem with the KA24DE. there are a few different types of O2 sensors depending on when you car was made (you must go by the manufacturing month and year, not the model year because they changed them mid-model year).

What happens if you have a bad oxygen sensor?

Rough Engine Idle. Vehicle engines that have a bad oxygen sensor often run irregularly or roughly. Oxygen sensors can control or contribute to many different engine functions, including fuel/air mixture, engine timing and engine combustion intervals.

How to diagnose a check on a 240sxone?

These codes are for a KA24DE, they will be different for different Nissan motors. So I went thought this process myself because my CEL came on. I checked it and it said my Front 02 sensor was bad (code 33). after resetting the ECM the CEL went away for a few weeks but it came back again.

Where is the OBDII port on a 240SX?

First of all if you’ve got a 96 or Newer 240sx (or other car) then you can use the OBDII (On Board Diagnostics V2) Port found below the Steering wheel, any auto parts store should be willing to plug in and read the code for you.

When to know if your O2 sensor is bad?

Still, because the light may indicate a variety of other problems, it is important to watch for bad O2 sensor symptoms. If you notice any, repairing the problem as quickly as possible is a good idea to prevent further trouble.

What does it mean when your oxygen sensor says P0420?

Oxygen sensors are only a part of a greater system, meaning if the p0420 code (or p0141, or p0135) is thrown, that doesn’t necessarily indicate the oxygen sensors need replacement. Rather, there could be something else in that system does that’s causing the oxygen sensors to appear faulty.

What causes an oxygen sensor to set trouble code?

A leaky exhaust pipe obviously can let exhaust gases out of the pipe at the leak. But air can also be sucked into the pipe at the same leak. If that leak is upstream of the sensor, it will see the extra oxygen and set a trouble code. This is a costly repair, but common with a p0420 code.

How many O2 sensors does a four cylinder engine have?

A car with a four-cylinder engine, on the other hand, may more commonly only have two. Operationally, O2 sensors are basic. If the fuel-to-oxygen ratio is off-balance, a chemical reaction creates voltage.
