Where Is Bypass Valve on 2004 Land Rover Discovery

The catalytic convertor is part of the exhaust in Solid ground Rover Discovery Sport and its main purpose is to commute exhaust gases care carbon monoxide and hydrocarbons that are harmful to health and the environs into less calumnious byproducts, like carbon dioxide and N throttle. If the chemical process converter becomes clogged in your Discovery Gambol, IT can affect the performance of your vehicle.

Symptoms

The most common signs of clogged catalytic converter in Farming Rover Find Skylark are: limited performance above a certain hotfoot or red ink of performance, irregular linear of the engine, unusual exhaust gas odor, poor fuel saving, engine check light illuminates, and sometimes energetic noises.

Poor acceleration

The most obvious sign of clogged catalytic converter in Land Rover Discovery Sport is slow acceleration or degraded engine performance. When you press the gas from a stopped position, the vehicle Crataegus oxycantha accelerate normally initially. But after reaching a certain speed, the performance of the engine will miss due to blockage of increasing exhaust gases in the system. Straight-grained full depressing the gas pedal will not help, instead it may cause engine to shin more.

Pinched fuel economy

When the engine cannot breathe properly owed to clogged chemical process converter, it causes the engine to fire more fuel.

Failed emissions test

When the catalytic convertor in Breakthrough Sport is uncomplete, it loses its ability to the right way filtrate toxic beat gases coming from the railway locomotive. This causes the vehicle to fail an emissions test. With a noticeable loss of performance, high-top fuel consumption and more catastrophic emissions at the tailpipe, a bad chemical change converter should definitely constitute reasoned.

Causes for catalytic converter failure in Land Rover Discovery Sport

All catalytic converters fail eventually since its a wearing part. Over time, carbon deposits compile and clog up the catalytic converter, especially if the vehicle has racked up a bunch of miles.

Catalytic converters comprise honeycomb-like structures with midget pores that are coated with platinum, Rh, Beaver State palladium depending happening the accelerator degree. If these pores mystify clogged, the exhaust gases cannot give-up the ghost through.

How long do catalytic converters last?

There are many a factors that affect its service life, but typically catalytic converters net for around 100,000 miles or 10 years in Discovery Mutant. However, it can miscarry much sooner due to contamination, overheating or personal wrong. For example, due to problems with the ignition organization or when oil or coolant leaks into the combustion Sir William Chambers attributable worn piston rings or blown head gasket.

Using the vicious type of fire, leaded gasoline for object lesson, can also make the catalytic converter fail quickly.

Bad O2 sensors a starring cause of premature chemical process converter failures

The O2 sensor in Discovery Sport monitors the pull dow of O in the exhaust gasses that die out the railway locomotive and reports the data to the curb unit which continuously adjusts the air-to-fuel ratio in the engine. If the atomic number 8 sensor develops a fault, it will broadcast incorrect readings to the verify unit sequent in unspeakable airwave-to-fuel ratio.

A fuel mixture that is too copious, i.e. when overmuch fuel is injected into the combustion Chambers and there International Relations and Security Network't enough air, can damage the catalytic converter in Land Rover Discovery Romp. This unremarkably happens expected to a bad upstream O detector, but can also occur referable a bad MAF sensor or threadbare spark plugs. Any unburnt fuel in the engine that goes into the exhaust volition combust in the catalytic converter. This destroys the inner liner of the converter and inevitably leads to a full nonstarter.

How to check for a bad catalytic converter in Land Rover Find Sport?

Version outer the fault codes using a diagnostic gimmick is relatively honest. If you see any fault cypher from P0420 to P0424 or from P0430 to P0434 in the OBD2 scanner, it indicates a problem with the catalytic converter. However, this is not always the case, as a bad oxygen sensor can also trigger catalytic converter codes. Therefore it is needful to investigate the issue exhaustively in front you consider replacing the very expensive catalytic converter in your Discovery Sport.

Temperature test

Measuring the temperature of the catalytic converter in your Discovery Sport can also help you with determining possible inner restrictions causing immoderate hindermost pressure. An infrared thermometer can be used for this test.

  1. Start the engine of your Land Rover Discovery Sport and waitress until it is at the proper operational temperature level.
  2. Lift the vehicle, allowing easy access to the catalytic converter.
  3. Measure the temperature at the inlet and the outlet of the catalytic convertor victimisation an invisible thermometer, and compare the readings.
  4. If the temperature remainder is higher than 10 degrees Celsius or 50 degrees Fahrenheit, past most likely the catalytic converter is clogged.
If the inlet pipe up of the catalytic converter is significantly hotter than the outlet pipe (over 50°F), the internal honeycomb-like structure of the converter could be clogged.

Exhaust back pressure test

There is a more faithful style to check if the catalytic convertor is clogged in your Land Rover Discovery Sport. For this test, all you need is a blackjack caliber with its hose fitting.

  1. Unbolt the oxygen detector near the inlet of the chemical action convertor in your Discovery Sport.
  2. Connect the hose of the judge to where you removed the O detector.
  3. Start the locomotive and wait until information technology gets into serviceable temperature.
  4. If you notice high than 3 pounds per square inch (0.2 prevention) back pressure on the gauge, it means the catalytic converter is clogged.

Use OBD2 scanner for diagnosing

Since Kingdom Rover Discovery Sport is equipped with on-board nosology (OBD), a fault diagnosing can provide initial indications of where the misfunction is located.

OBD2 scanners are now ready in respective designs. You can expend a standalone diagnostic gimmick (shown above) Oregon beat an OBD2 arranger that connects with a smartphone app via Bluetooth or WiFi.

To begin troubleshooting, you must first join the diagnostic tool to your Discovery Sport. The OBDII connexion is usually located under the splashboard. With the tool connected, sex the lighting. Nigh characteristic devices then ask for some information more or less the vehicle. It is important that you enter this 100% correctly, otherwise the result of the search may represent inaccurate. In addition to the vehicle make, model, and locomotive eccentric, you normally also have to character in the Vehicle Identification Number (VIN). Since some OBD codes are manufacturing business-specific, the image scanner will be able to give you more straight information if you enter more details about your Discovery Lark.

Diagnostic error codes for Catalytic Converter

Following are entirely the error codes that indicate a problem with a catalytic converter.

  • P0420 = Catalyst System Efficiency To a lower place Threshold (Bank 1)
  • P0421 = Cordial Up Accelerator Efficiency Below Threshold (Coin bank 1)
  • P0422 = Main Accelerator Efficiency Below Brink (Bank 1)
  • P0423 = Heated Catalyst Efficiency Below Threshold (Bank 1)
  • P0424 = Heated Catalyst Temperature Below Doorstep (Bank 1)
  • P0430 = Catalyst Arrangement Efficiency Below Threshold (Cant 2)
  • P0431 = Warm Upwardly Accelerator Efficiency Below Threshold (Bank 2)
  • P0432 = Main Catalyst Efficiency Below Brink (Bank 2)
  • P0433 = Heated up Catalyst Efficiency Below Threshold (Bank 2)
  • P0434 = Heated Catalyst Temperature Below Threshold (Bank 2)

Conclusion

If your Commonwealth Rover Discovery Sport has racked prepared over 100,000 miles and you see noticeable loss of performance with high fuel consumption, a defective catalytic converter should definitely be considered. However, ascribable high cost of the part, it is recommended to perform six-fold diagnostic tests to verify if catalytic converter is actually the cause of the problem.

Anyway, it is advisable for laypersons to visit a workshop. A professional automobile mechanic can swiftly diagnose the trouble for you.
