![]() What you are left with is more money spent at the pump and more frequent trips to the gas station. If there’s more fuel than air, your defective oxygen sensor might not be able to detect it.Īs more fuel burns in the engine, your gas mileage decreases. Inside the combustion chambers, there must be the right amount of air and fuel mixing. With this in mind, you can see any number of trouble codes relating to an air-fuel mixture imbalance that could ultimately be caused by the oxygen sensor. In many cases, there can be a trouble code related to the oxygen sensor, and you don’t notice any other bad o2 sensor symptoms at all.Īll of the trouble codes P0030, P0031, P0130, P0131, P0132, P0133 and P0134 have to do with the oxygen sensors. One of the most common bad oxygen sensor symptoms is a check engine light on your dashboard. Here is a more detailed list of the bad oxygen sensor symptoms: 1. You may also notice reduced fuel economy, and the car may fail an emissions inspection. The most common bad oxygen sensor symptoms are poor engine performance and rough idle, along with a check engine light on your dashboard. If you have anything that you would like to add, please feel free to leave a comment below.Conclusion What Are The Symptoms Of A Bad Oxygen Sensor? Good luck finding whatever caused P0137 in your Honda Odyssey. If the light comes on, even for a second, you know that you have a short circuit causing the P0137 trouble code. If it’s not getting any voltage, attach the test light to the harness plug and shake the wiring a little bit. ![]() You can also use a voltage test light to determine whether or not the oxygen sensor is getting any voltage at all (they’re about $5 at Walmart). If it ends up being a wiring issue, it’ll save you money over buying an unnecessary O2 sensor. If you don’t have access to a multimeter, it certainly wouldn’t hurt to check the wiring to between the fuse box and the Oxygen sensor first. If you use the multimeter, you’ll know whether or not the voltage coming to and from the oxygen sensor is within spec, this can help you determine if it’s your Odyssey’s O2 sensor, or wiring harness that’s the issue. It is possible to diagnose the P0137 with a multimeter. Here is a fantastic video that covers all aspects of diagnosing the P0137 code:
