Acura RSX Catalytic Converter: Troubleshooting it at Home

Troubleshooting the Acura RSX catalytic converter is very important to know whether it already needs to be replaced or you can still go on with it for a few more months. Basically, the converter decreases the dangerous emissions from the exhaust by transforming them into harmless gases. To find out if yours need to be replaced with a new one, here are some tips to help you troubleshoot at home.

Antifreeze or oil enters the exhaust

Once oil or antifreeze enters the exhaust system, it can block the passage of air, thus creating heavy carbon filth that can cover the catalyst. This can cause two problems: first, carbon deposits could clog up the pores in the catalyst and block the exhaust flow; second, the carbon deposits keep the catalytic converter from lessening the dangerous emissions from the exhaust flow. Check if there are defective valve seals, worn-out piston rings, damaged gaskets, or deformed engine components because these are some of the reasons why antifreeze or oil enters the exhaust.

Surplus fuel enter the exhaust

Take note that the fuel is supposed to burn in the combustion chamber alone. If this leaves the chamber unburned, it could go into the exhaust and light off once it reaches the catalytic converter. This will result in heating up the converter above the usual operating conditions and will melt down. Inspect if there are any wrong fuel mixture, rotten spark plugs, defective oxygen sensor, wrong timing, sticking float, damaged fuel injector, or a check valve failure. These are usually the causes why surplus fuel enters the exhaust.

Engine is out of tune

If there are problems occurring in the catalytic converter, an engine tune-up may be required. The damage that's caused by an out of tune engine is usually because of wrong timing, misfiring spark plugs, or incorrect fuel⁄air mixture. If this is not attended to, it could lead to catalytic converter failure or damage.

Spark plugs no longer fire

If the spark plugs do not fire anymore, it can cause unburned fuel to enter the exhaust system. If this happens, the unburned fuel lights up inside the catalytic converter and will cause it to melt down the catalyst. Check the spark plug or the spark plug wires once in a while for cracks or damage. If they no longer fire, these need to be replaced.

  • Making Your Acura RSX Catalytic Converter Last Longer With These Tips

    Replacing the Acura RSX catalytic converter can be really expensive. The average cost is usually around $50-$500, but the high-end replacement ones cost around $400-$2,000. You wouldn't want to pay for that much, would you? So instead, make your Acura RSX catalytic converter last longer by following some of these maintenance tips.

    • Clean up the clogged up catalytic converter
    • A clogged up catalytic converter can cause the exhaust to release harmful emissions. Listen to your engine while stepping on the accelerator. If the engine experiences unequal delivery of power or it hesitates, then the catalytic converter is clogged up. If this is the case, have your vehicle checked and be cleaned. If this can't be resolved, you have no choice but to get it replaced with a new one. Or else, it could cause engine stalling if the backpressure becomes too high.
    • Clear the catalytic converter codes
    • If there are error codes on your car computer, it indicates that there is a defective catalytic converter. This error is usually coming from the oxygen sensor. Remember that the sensor must be in good condition before fixing the converter. To clear the catalytic converter codes, disconnect the battery first to reset the computer. Find and remove the oxygen sensor and take it to the auto store. Look for a spark plug defouler and make sure it matches the sensor; purchase two. At home, you can install the oxygen sensor into the defouler and reconnect all the wires and battery.
    • Check the engine
    • If the vehicle starts to run rough, creates smoke from the tailpipe, or if the check engine light appears, a technician must immediately check the catalytic converter. If you continue to ignore the blinking check engine light, it can cause greater damage to the convert and would need to be replaced. You can tell that the converter is defective if the performance is poor, the engine temperature has increased, there's a failure in the emissions test, and if there's a hesitation or bucking. So if you don't want to pay for an expensive catalytic converter replacement, have this inspected by a technician.
