Ortsmatt Posted November 28, 2023 Share Posted November 28, 2023 After replacing both lambda sensors on my 2008 Rio, I have noticed that the check light sometimes illuminates and then extinguishes a few days later. After connecting my OBD metre, it indicates that the post catalytic converter sensor is malfunctioning. However, when I had it inspected at Kia, they reported no problems. Does anybody have any suggestions? Quote Link to comment Share on other sites More sharing options...
SkippyTom Posted November 28, 2023 Share Posted November 28, 2023 Are the sensors same or do they vary, and have you installed them in reverse order? Additionally, the fact that a sensor is new does not guarantee its functionality. Quote Link to comment Share on other sites More sharing options...
Ortsmatt Posted November 28, 2023 Author Share Posted November 28, 2023 Thank you one again. The sensors are accurate. I will need to change the second sensor once more. It has been suggested that the issue may be due to a defective catalytic converter. What is your opinion on this matter? Quote Link to comment Share on other sites More sharing options...
Darrellll Posted November 28, 2023 Share Posted November 28, 2023 May I know the specific trouble code, please? Quote Link to comment Share on other sites More sharing options...
Ortsmatt Posted November 28, 2023 Author Share Posted November 28, 2023 I will establish a connection and inform you accordingly. Quote Link to comment Share on other sites More sharing options...
SkippyTom Posted November 28, 2023 Share Posted November 28, 2023 Malfunctioning felines will often regurgitate an error code. I have seen that Max inquired about the logging of a code and you are planning to verify it. Another method of identifying a defective automobile is by olfaction, namely by detecting an unpleasant odour like that of rotten eggs.

Ortsmatt Posted November 28, 2023 Author Share Posted November 28, 2023 The code is P0141. There is no smell of eggs. Quote Link to comment Share on other sites More sharing options...

Darrellll Posted November 28, 2023 Share Posted November 28, 2023 There is a fault in the heater circuit of the bank. There is one sensor, number two. Or anything said in a very same manner. I am uncertain if the female terminals are located on the engine loom or the sensor loom side. If the wires are located on the engine loom side and you still have the original sensor, you may extract one of the wires, together with the crimped-on terminal, from its plastic socket. This wire can then be used to assess the tension of the female terminals in the corresponding socket. It is possible that the weak tension might be due to someone tampering with and opening one of the probes during diagnostic. Is the heating circuit supplied with a 12-volt power source? It is necessary to inspect the continuity of the wires connecting the ECU socket and the sensor socket. Typically, the resistance should be below 0.4 ohms, while Kia specifications allow for a resistance below 1 ohm. Additionally, ensure to verify the continuity between the wires and the ground. It should exhibit an infinite resistance (indicating an open circuit). If any megaohms value is obtained, it is imperative to thoroughly investigate any potential electrical leakage to the ground. I have seen instances where looms coming into contact with the side of the ECU bracket have resulted in many engine loom problems. I have had instances when the wires have broken within the protective covering next to the tightly secured connection point. As a precautionary measure, I often apply a little force to each wire at the back of the socket (specifically the end of the wiring harness near the sensor, not the electronic control unit) to check for any signs of weakness or breakage. After completing all the necessary tasks, it would indicate that the new sensor is defective. Although uncommon, it is possible for the sensor itself to be defective, even when using components provided by the dealer. I trust that the information provided is beneficial.

SkippyTom Posted November 28, 2023 Share Posted November 28, 2023 An improved version provided by my friend Eric. Appreciate the fact that you do not own this particular automobile. Quote Link to comment Share on other sites More sharing options...
Ortsmatt Posted November 28, 2023 Author Share Posted November 28, 2023 I will thoroughly explore all potential options and hopefully discover a solution. Quote Link to comment Share on other sites More sharing options...
