What does P1135 code mean?
air/fuel sensor heater circuit
OBD-II code P1135 represents a general fault in the air/fuel sensor heater circuit for bank 1, sensor 1. Shop OEM sensors here. The air/fuel ratio sensor needs to reach a certain operating temperature, a minimum of 1200 degrees Fahrenheit, to create accurate voltage signals.
What does Engine code P1150 mean?
OBD II fault code P1150 is a manufacturer specific code that is defined by carmaker Toyota and by extension, Lexus, as “Air/Fuel Ratio Sensor Circuit Range/Performance Malfunction Bank 2 Sensor 1.
How do you know if your air fuel sensor is bad?
Symptoms of a defective Oxygen/Air-Fuel Ratio Sensor: Common indications of a bad oxygen/air-fuel ratio sensor include rough idling, engine pinging, poor gas mileage and increased exhaust emissions. One of the first symptoms of a faulty sensor is the lighting up of the “Check Engine” light.
Can you clean an air fuel ratio sensor?
Oxygen and air fuel ratio sensors can’t be cleaned in a way that will affect their performance. You can clean it to make it shiny. The ceramic element has a spray cleaner on it. That could make you feel better.
How do I fix my P1135 code?

- If the fault is from a poor electrical connection, you can check the wires and repair the connections.
- Also, you can correct any leaks emanating from the exhaust of the vacuum.
What is the air fuel ratio sensor?
The air fuel ratio sensor is typically in the exhaust manifold or in the front exhaust pipe. It measures the oxygen in the exhaust and sends that information to the ECU. The ECU, based on the air-to-fuel ratio, adjusts the blend to keep it at the prime level. This level is generally 14.7:1.
Where is the A F sensor located?
exhaust manifold
The air fuel ratio sensor is typically in the exhaust manifold or in the front exhaust pipe. It measures the oxygen in the exhaust and sends that information to the ECU.
