#2002 KIA SPECTRA WIRING HARNESS CODE#
This code is relatively straightforward to diagnose.
Here’s more on the symptoms of a bad ECM. It is technically possible that the ECM has gone bad when everything seems to be working, but you still get this code anyway. The good news is, they are affordable and easy to replace. It is highly likely that the oxygen sensor has gone bad when you get this code.
#2002 KIA SPECTRA WIRING HARNESS HOW TO#
Here’s a great video from Ratchets and Wrenches on how to test the wiring on a heated O2 sensor: If the oxygen sensor is getting power to it, you can check to see if it is getting the correct level of voltage/ohms. Make sure to test the ground circuit for continuity. You can take a simple test light and check to see if the harness is getting voltage. If the harness looks like it is intact, you’ll next want to to test and make sure that the heated oxygen sensor is getting power. Pay particular attention to anywhere that the harness comes close to touching other metal, and where it is closest to the exhaust. A visual inspection will often uncover exposed wiring (that’s shorted) or wiring that is broken altogether. Hot exhaust can make the wiring harness brittle. A quick examination of the Spectra’s physical wiring harness, as well as the voltage coming from the heated O2 sensor can save you from buying a sensor that you don’t need.ĭue to the location of the oxygen sensors (under your Spectra, on the hot exhaust pipes), the wiring harness around them is easily susceptible to damage. The most common cause of P0031 is a bad oxygen sensor. This indicates a random misfire in the cylinders. If the engine is running rough, it very well may be accompanied by the P0300 code. Raw Fuel Smell Coming From Exhaust (particularly when cold).P0031 is most often not accompanied by any noticeable symptoms as long as it is the only code that is currently stored in the ECM’s memory. If these are the only two codes present, fixing what is causing P0031 will more than likely clear the P0171. It indicates that the Spectra has a lean condition. With P0031, the O2 sensor is informing you that the heater circuit resistance is lower than the normal operating range. When this heater is not operating, it can affect the way that the engine runs. As stated above, the oxygen sensor has a heater that helps to give it a more accurate reading. The job of the O2 sensors in your Spectra is to measure the level of oxygen in the exhaust so that the ECM can make changes to the air fuel ratio. The heated element in the oxygen sensors helps to get a more accurate reading of the oxygen in the exhaust. Without a good reading, it is difficult for the ECM to determine the proper air/fuel mixture to give the engine. When the engine is cold, it has a hard time getting a good reading from the Spectra’s oxygen sensors. Sensor 1 is upstream of the catalytic converter.Bank 1 is the side of the engine with cylinder 1. If you have a four cylinder engine or inline six, it’s the only bank.
