How to Tell if the Catalytic Converter Has Been Removed?

You can check by its appearance. A normal catalytic converter should have uniformly arranged and evenly sized pores in its internal porous ceramic, which should also be clean and relatively white (a yellowish beige color indicates a counterfeit). The porous ceramic inside the catalytic converter serves as a carrier and should be firmly and securely assembled with the outer shell, with no signs of looseness. A replacement catalytic converter should match the original factory specifications in terms of size, the material of the internal porous ceramic, the arrangement of the pores, and the number of rows. Additional information: 1. The catalytic converter is the most important external purification device installed in a car's exhaust system. It converts harmful gases such as CO, HC, and NOx emitted from the car's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 2. When high-temperature exhaust gases pass through the purification device, the catalyst in the catalytic converter enhances the activity of CO, HC, and NOx, promoting specific oxidation-reduction chemical reactions. CO oxidizes at high temperatures into colorless, non-toxic carbon dioxide gas; HC compounds oxidize into water (H2O) and carbon dioxide; and NOx is reduced into nitrogen and oxygen. These three harmful gases are transformed into harmless gases, thereby purifying the car's exhaust.

Is it necessary to repair transmission noise?

Transmission noise should be repaired. The causes of transmission noise failure are as follows: 1. Deformation of the transmission housing; 2. Loose or disassembled bearings; 3. Severe gear wear or broken teeth; 4. Overloading may cause bending of the transmission input or output shaft, or severe wear of the splines on the shaft; 5. Severe wear of the synchronizer. The following are the precursors of transmission failure: 1. Symptoms of transmission slipping. Fault performance: During driving, you can hear the engine idling when accelerating, but the car does not show a significant speed increase and has weak acceleration; another situation is that the car drives normally on flat roads but has weak power when going uphill, and the engine speed is very high. 2. Transmission noise. Fault performance: When the car is idling, driving, or under high-load driving, you hear abnormal noises from the transmission, even loud noises, and there are irregular, dull sounds when shifting gears. 3. Overheating of the transmission. Fault performance: The computer alarm shows that the transmission temperature is too high during driving; or after driving for a while, you feel that the transmission is overheating, even too hot to touch. 4. Symptoms of transmission oil leakage. Fault performance: You can clearly feel that the car is difficult to start, and during driving, although the engine speed increases when stepping on the accelerator, the car does not show obvious signs of acceleration.

What is broken with the P0507 fault code?

P0507 fault code: It means the idle air control system engine speed is higher than the expected value. Possible causes include air leakage after the throttle body, IAC control circuit failure, IAC solenoid valve failure, throttle valve control module failure, electronic control module (PCM or ECM) failure, vehicle speed sensor failure, etc. The solutions are: 1. Check if the throttle is too dirty, then read the working data stream of the throttle position sensor and intake pressure sensor, and clean or replace the throttle. 2. If certain sensors have failed, it may cause the engine to malfunction. The sensors need to be replaced.
