Where Is the Bcm Located on 2003 Saturn Vue
The catalytic converter is depart of the exhaust organisation in Saturn Vue and its main purpose is to commute exhaust gases like carbon monoxide and hydrocarbons that are harmful to health and the environment into less harmful byproducts, similar carbon dioxide and N gas. If the catalytic converter becomes clogged in your Vue, IT can affect the execution of your vehicle.
Symptoms
The most common signs of encumbered catalytic convertor in Saturn Vue are: limited performance preceding a indisputable speed or loss of performance, irregular running of the railway locomotive, unusual exhaust gas odor, poor fuel saving, locomotive check light illuminates, and sometimes rattling noises.
Poor acceleration
The just about obvious sign of clogged chemical process converter in Saturn Vue is adagio acceleration or fast engine performance. When you press the petrol treadle from a stopped position, the fomite may accelerate normally initially. Simply after reaching a convinced speed, the performance of the locomotive testament discharge collectible to blockage of increasing sap gases in the system. Even full grim the vaunt treadle will not help, instead it may movement engine to sputter more.
Poor fuel saving
When the engine cannot catch one's breath properly due to choked chemical action converter, it causes the engine to burn more fire.
Failed emissions test
When the catalytic convertor in Vue is broken, it loses its power to properly filter KO'd virulent exhaust gases coming from the engine. This causes the fomite to fail an emissions test. With a noticeable loss of execution, high fuel consumption and more harmful emissions at the tailpipe, a defective catalytic convertor should definitely embody well-advised.
Causes for catalytic converter failure in Saturn Vue
All catalytic converters neglect eventually since its a wearing take off. Over time, carbon copy deposits collect and clog up the catalytic converter, especially if the fomite has racked up a lot of miles.
How long cause chemical change converters last?
There are umteen factors that affect its service life, but typically chemical change converters last for close to 100,000 miles or 10 years in Vue. However, it can break dow more than in the first place collect to contamination, overheating operating theater physical damage. For example, due to problems with the ignition system Beaver State when oil operating theatre coolant leaks into the combustion Chambers attributable scoured piston rings OR pursy chief gasket.
Using the wrong type of fire, leaded gasoline e.g., can also make the catalytic converter cristal bad quickly.
Bad O2 sensors a leading cause of previous catalytic convertor failures
The O2 sensor in Vue monitors the level of oxygen in the consume gasses that exit the engine and reports the data to the control whole which continuously adjusts the air-to-fuel ratio in the engine. If the oxygen sensor develops a fault, it will send incorrect readings to the verify building block resulting in bad air-to-fire ratio.
A fuel mixture that is too rich, i.e. when to a fault more than fuel is injected into the burning chambers and there ISN't enough air, can damage the catalytic converter in Saturn Vue. This commonly happens cod to a stinky upstream oxygen sensor, just can also happen expected to a negative MAF sensor or worn spark plugs. Whatsoever unburnt fire in the engine that goes into the exhaust scheme wish ignite in the catalytic converter. This destroys the inward lining of the converter and inevitably leads to a total failure.
How to stoppage for a rotten catalytic converter in Saturn Vue?
Reading out the error codes using a diagnostic device is relatively reliable. If you see any fault code from P0420 to P0424 or from P0430 to P0434 in the OBD2 image scanner, it indicates a problem with the catalytic converter. However, this is non always the case, as a bad oxygen sensor can also trigger catalytic convertor codes. Therefore information technology is necessary to investigate the issue thoroughly before you consider replacing the very expensive catalytic convertor in your Vue.

Temperature test
Measuring the temperature of the chemical action convertor in your Vue can also help you with determining possible inner restrictions causing excessive back out pressure. An infrared thermometer can be used for this test.
- Start the engine of your Saturn Vue and hold off until information technology is at the right work temperature level.
- Lift the vehicle, allowing easy access to the catalytic converter.
- Measure the temperature at the inlet and the outlet of the catalytic converter using an infrared thermometer, and compare the readings.
- If the temperature difference is high than 10 degrees Celsius or 50 degrees Fahrenheit, and then well-nig likely the catalytic converter is clogged.
Exhaust back pressure examination
In that respect is a more accurate way to check into if the catalytic converter is clogged in your Saturn Vue. For this test, all you need is a pressure gage with its hose fitting.
- Unbolt the oxygen sensor near the inlet of the catalytic converter in your Vue.
- Relate the hose of the gauge to where you removed the oxygen sensing element.
- Start the engine and wait until it gets into operational temperature.
- If you notice high than 3 psi (0.2 bar) back pressure on the gauge, it means the catalytic converter is clogged.
Use OBD2 scanner for diagnosis
Since Saturn Vue is transistorised with on-board diagnostics (OBD), a fault diagnosis can provide initial indications of where the malfunction is located.
To start out troubleshooting, you mustiness first connect the diagnostic tool to your Vue. The OBDII connector is usually placed nether the dashboard. With the tool connected, turn to connected the ignition. Most diagnostic devices so ask for some information about the fomite. IT is important that you enter this 100% correctly, other the leave of the seek whitethorn embody inexact. In addition to the vehicle make, model, and engine typewrite, you usually also have to type in the Vehicle Identification Number (VIN). Since some OBD codes are maker-peculiar, the scanner wish be able-bodied to give you more correct information if you enter many details about your Vue.
Diagnostic error codes for Catalytic Converter
Following are all the error codes that show a problem with a catalytic converter.
- P0420 = Accelerator System Efficiency Below Threshold (Bank 1)
- P0421 = Warm Up Catalyst Efficiency Under Threshold (Bank 1)
- P0422 = Main Catalyst Efficiency Below Threshold (Bank 1)
- P0423 = Heated Catalyst Efficiency Down the stairs Threshold (Banking company 1)
- P0424 = Heated Catalyst Temperature Below Threshold (Bank 1)
- P0430 = Catalyst System Efficiency Below Threshold (Bank 2)
- P0431 = Warm Up Catalyst Efficiency Below Doorstep (Camber 2)
- P0432 = Main Catalyst Efficiency Below Threshold (Bank 2)
- P0433 = Heated up Catalyst Efficiency Below Threshold (Bank 2)
- P0434 = Heated Accelerator Temperature Below Threshold (Bank 2)
Conclusion
If your Saturn Vue has racked up over 100,000 miles and you see noticeable loss of performance with high fuel consumption, a defective catalytic converter should definitely be considered. However, attributable high monetary value of the component, it is recommended to perform multiple symptomatic tests to verify if chemical action converter is actually the lawsuit of the problem.
In any caseful, it is advisable for laypersons to visit a workshop. A professional mechanic can fleetly name the problem for you.
