P0420 Error code P0420 indicates a problem with the efficiency of the catalytic converter in the exhaust system. This could be caused by issues such as a faulty catalytic converter, oxygen sensor, or exhaust leak. Some potential solutions for addressing error code P0420 include: 1. Check the oxygen sensors: Inspect the upstream and downstream oxygen sensors to ensure they are functioning properly. Replace any sensors that are faulty. 2. Check for exhaust leaks: Inspect the exhaust system for leaks, particularly around the catalytic converter. Repair any leaks found. 3. Replace the catalytic converter: If the catalytic converter is determined to be faulty, it may need to be replaced. Ensure that the replacement meets the specifications for your vehicle. 4. Clear the error code: After addressing potential issues, clear the error code and observe if it returns. If the issue is resolved, the code should not reappear. It's important to have the vehicle diagnosed by a qualified mechanic to determine the exact cause of the error code and to address any potential issues. Ignoring this issue may lead to increased emissions and poor engine performance. P1135 The error code P1135 typically indicates a problem with the Air/Fuel Ratio Sensor Heater Circuit Malfunction (Bank 1 Sensor 1). This sensor is located in the exhaust system in front of the catalytic converter. Here are a few potential causes and solutions for this error code: 1. Faulty Air/Fuel Ratio Sensor: The sensor may be malfunctioning and need replacement. 2. Wiring or Connector Issues: There could be wiring or connector problems leading to poor electrical connections. Inspect the wiring and connectors for any damage or corrosion. 3. Exhaust System Leaks: Leaks in the exhaust system can affect sensor performance. Check for any leaks and repair as necessary. 4. Vacuum Leaks: Vacuum leaks can affect sensor readings. Inspect the vacuum lines for any leaks and fix them. 5. Exhaust System Contamination: The sensor could be contaminated by oil or coolant. Inspect the sensor for contamination and clean or replace as needed. It's important to have the vehicle inspected by a qualified mechanic to diagnose the exact cause of the error code. They can perform tests and checks to determine the specific issue and recommend the appropriate solution to resolve the P1135 error code. Ignoring this issue may lead to poor fuel economy and increased emissions. |
