Most diagnostic devices then ask for some information about the vehicle. With the tool connected, turn on the ignition. The OBDII connector is usually located under the dashboard. ![]() To begin troubleshooting, you must first connect the diagnostic tool to your Odyssey. You can use a standalone diagnostic device (shown above) or get an OBD2 adapter that connects with a smartphone app via Bluetooth or WiFi. OBD2 scanners are now available in various designs. Since Honda Odyssey is equipped with on-board diagnostics (OBD), a fault diagnosis can provide initial indications of where the malfunction is located. So if your Odyssey develops a greater thirst for gas, you should definitely consider checking or replacing O2 sensor, especially if the vehicle has racked up more than 100,000 miles. Will a new O2 sensor improve gas mileage?Īccording to EPA, replacing a bad oxygen sensor can improve fuel economy by as much as 40 percent. A comparison between new and old O2 sensor. When the O2 sensor goes bad, it causes improper air-to-fuel mixture in the combustion chambers which can cause the engine to shake, these vibrations can be felt in the cabin of the vehicle when driving. Can a bad O2 sensor cause shaking?Ī faulty O2 sensor can certainly cause shaking or vibrations in Honda Odyssey when driving. Since a rich or lean condition robs a vehicle of power, a bad oxygen sensor can cause poor acceleration. The engine runs too “lean” or too “rich”. The optimal amount of fuel can no longer be calculated which results in either too little or too much fuel injected into the combustion chambers. If the oxygen sensor goes bad in Odyssey, it does not send correct measured values to the engine control unit. Can a bad O2 sensor cause poor acceleration? And if you continue driving for several months, it may lead to engine damage or catalytic converter failure which can cost thousands of dollars to fix or replace. What happens if you keep driving with a bad O2 sensor?ĭriving your Honda Odyssey with a bad O2 sensor can cause sluggish and rough acceleration, along with high fuel consumption and emissions. Connect the electrical plug of the new sensor.Screw in the new O2 sensor by hand and tighten it up with a wrench.Apply anti-seize lubricant to the threads of the new sensor.Make sure the engine is cold before replacing the sensor to prevent burn injury. All you need is a wrench for this replacement job. You don’t necessarily have to visit a workshop to replace oxygen sensor in your Honda Odyssey. You can also perform a continuity test on the connector of the sensor with a multimeter to check if the heater circuit is broken. If you see any error code from P0130 to P0135 or from P0150 to P0155, it indicates a problem with the upstream oxygen sensor. You can diagnose the problem by connecting an OBD2 scanner to your vehicle. If there is any fault in the oxygen sensor, it usually illuminates the engine check light in the instrument cluster of Honda Odyssey. How to check for bad O2 sensor in Odyssey? This suffocates the engine and causes performance issues. because of bad O2 sensor), the exhaust gases cannot pass through easily. ![]() If these pores get clogged due to improper engine combustion (e.g. Catalytic converters contain honeycomb-like structures with tiny pores that are coated with platinum, rhodium, or palladium depending on the catalyst stage. Because O2 sensors are relatively cheap compared to the price of catalytic converters, which can easily cost you over a thousand dollars to replace. If you suspect a problem with O2 sensor in your Odyssey, you should act immediately and get it checked by a professional mechanic. Bad O2 sensors lead to catalytic converter failureįaulty oxygen sensors are the leading cause of premature catalytic converter failures. If this sensor goes bad, it does not have any affect on the engine performance, but the check engine light may illuminate and you may see error codes related to catalyst efficiency. The main purpose of downstream O2 sensor is to ensure that the catalytic converter is functioning properly. The downstream O2 sensor in Odyssey is located further down the exhaust system, after the catalytic converter, and is responsible for measuring the level of pollutants passing through the catalytic converter. Downstream O2 sensors do not affect engine performance Any fault in this sensor can cause all sorts of performance issues in your Odyssey. The upstream O2 sensor helps in maintaining proper air to fuel ratio in the combustion chambers for maximum fuel efficiency and engine performance. But the most important one is the upstream O2 sensor, the one that is closest to the engine, usually in the exhaust manifold. There are multiple O2 sensors in Honda Odyssey, how many depends on vehicle configuration and model year. Upstream and downstream O2 sensors Upstream O2 sensors are important for engine performance
