What Causes the Exhaust Fault in the Tayron?
3 Answers
If the exhaust fault light in the Tayron illuminates, it indicates a failure of the three-way catalytic converter in the vehicle's exhaust system. Below is more information about the three-way catalytic converter: 1. The internal structure of the three-way catalytic converter is a mesh design coated with a purifying agent. 2. The three-way catalytic converter reduces the levels of pollutants in the exhaust gases. 3. The three-way catalytic converter is installed at the front section of the exhaust system, located behind the exhaust manifold. 4. Both the front and rear of the three-way catalytic converter are equipped with oxygen sensors. The front oxygen sensor primarily measures the oxygen content in the exhaust, allowing the ECU to adjust the air-fuel ratio; the rear oxygen sensor mainly detects whether the three-way catalytic converter has failed.
My Tharu previously had an exhaust system malfunction - extremely loud exhaust noise accompanied by foul odors. After inspection, it was found to be an exhaust pipe leak. Upon reflection, the damage might have been caused by road impact or long-term corrosion creating small holes. Another common cause is catalytic converter blockage; severe carbon buildup can restrict exhaust flow and trigger the malfunction indicator light. Aging oxygen sensors may also contribute by sending inaccurate signals that affect engine performance. If left unrepaired, these issues can lead to drastically increased fuel consumption and, in severe cases, overheating that damages exhaust components. I was constantly anxious while driving, so I promptly took it to a professional shop for comprehensive maintenance and applied anti-rust coating to prevent future leaks.
Checking exhaust issues requires a step-by-step approach. Once my Tayron had abnormal exhaust, and I suspected it was either a catalytic converter problem or a faulty oxygen sensor, as the car accelerated slower and the exhaust smelled bad. Later, I used an OBD scanner to read the fault codes, and sure enough, the oxygen sensor reported excessively high values. After replacing it, the situation improved immediately. Other causes include loose exhaust pipe connections leading to leaks, or carbon buildup due to impure fuel. A simple self-check can involve seeing if the fuse is blown, saving both money and hassle. But for a thorough fix, it's best to have a technician inspect the pipes and ECU system to ensure emissions meet standards, keeping things both eco-friendly and safe.
