Thanks to its outstanding engine, the Land Rover Discovery is one of the first choices of English royals when it comes to off-road SUVs. This, however, will not be possible without the Land Rover Discovery oxygen sensor. This small device found in different parts of the exhaust system detects rich and lean oxygen-fuel mixture. Through this function, the engine runs more efficiently and only the right amount of fuel is used. A faulty oxygen sensor will make the Land Rover Discovery computer guessing, leading to poor engine performance and increased fuel consumption. With this, a damaged oxygen sensor should be replaced the soonest.

Frequently Asked Questions Ask APW

How long does the Land Rover Discovery oxygen sensor replacement normally take place? Answer: Because there are four or more oxygen sensors inside the Land Rover Discovery, replacing these can last from 30 minutes to an hour depending on the DIY skill level of the owner. The replacement involves working under the Land Rover Discovery. Tools to be used include screwdrivers, a ratchet wrench, and an anti-seize compound. Almost anyone can do it as long as guided properly.

What is wrong when trouble code P0174 continues to flash even after replacing the oxygen sensor? Answer: The P0174 code generally means that an oxygen sensor in the Land Rover Discovery has been detecting a lean mixture in the exhaust system. The initial thing to do is check the engine and exhaust system because the fault may not be with the new oxygen sensor. A probable cause of this issue is through a leak in the exhaust system. This leak can bring in more air for the oxygen sensor to detect, resulting in a lean mixture.

How difficult is cleaning an oxygen sensor in the Land Rover Discovery? Answer: Varnish, gums, and other contaminants in the exhaust system can cover the oxygen sensor and keep it from working. A dirty Land Rover Discovery oxygen sensor can lead into more serious problems from the catalytic converter and the engine. To make sure that the oxygen sensor is working properly, it is recommended to constantly clean it. Good news is that cleaning the oxygen sensor is fairly easier than cleaning most parts in an automobile. The best way is by adding an auto marine motor treatment to the fuel tank and driving the Land Rover Discovery. The strong solution will break down the build-up in the oxygen sensor. However, the solution contains petroleum distillates that can harm eyes and skin and damage the vehicle's paint. With this, appropriate care should be applied when using the auto marine motor treatment.

What are the tools needed in testing the Land Rover Discovery oxygen sensor? Answer: The only thing needed in testing the oxygen sensor is an oscilloscope. This is basically a device that measures the changes in signal voltages in electronic devices such as the oxygen sensor. Testing the device involves attaching the oscilloscope to it and driving the Land Rover Discovery for up to 2000 rpm. An oxygen sensor should be replaced if the oscilloscope shows no change or slow response time.
