check it out and let me know. how does the car drive? * the easiest way to test for a bad conerter is to unplug ita t the manifold. you will need two new bolts since the old ones will snap off. take for a drive. Warning, it will be VERY loud. bring license and registration, as well as a good story. before heading out clear all codes by disconnecting negative terminal for 10 seconds. if at the end of the trip the codes are gone, then you have your answer.

What does code p0137 mean on a 2003 hyundai santa fa?
Code P0137 on a 2003 Hyundai Santa Fe indicates a problem with the oxygen sensor circuit, specifically the downstream (post-catalytic converter) oxygen sensor. This code typically means that the sensor is reading a low voltage, which can suggest a malfunctioning sensor, a problem with the wiring or connectors, or issues with the catalytic converter. It’s important to diagnose the problem accurately to ensure proper engine performance and emissions control.
Where is the 02 sensor located on 2001 Chevrolet Malibu?
All oxygen sensors are located in the exhaust system. Some have one in the manifold, some have one before the catalytic converter. Then others have one before and one after the converter. It requires a special socket to remove and replace it. Just because your code says oxygen sensor, does not mean it is bad. A vacuum leak can give a code that the sensor is reading lean.
