Subheading 1: What is the P1135 code in Toyota Camry?

The P1135 code in a Toyota Camry refers to a malfunction in the Air/Fuel Ratio Sensor Heater Circuit Bank 1 Sensor 1. This code indicates that there is an issue with the heater circuit of the sensor responsible for measuring the air/fuel ratio in the engine. It is important to address this code promptly as it can affect the performance and efficiency of the vehicle.

Subheading 2: Symptoms of a P1135 Code in Toyota Camry

Symptom 1: Illuminated Check Engine Light: The first noticeable symptom of a P1135 code is the illumination of the check engine light on the dashboard. This serves as a warning sign that there is an issue with the air/fuel ratio sensor.

Symptom 2: Decreased Fuel Efficiency: Another common symptom is a decrease in fuel efficiency. This occurs because the faulty sensor cannot accurately measure the air/fuel mixture, leading to inefficient combustion and increased fuel consumption.

Symptom 3: Rough Idling or Stalling: A malfunctioning air/fuel ratio sensor can also cause the engine to idle roughly or even stall. This irregular idling is due to incorrect fuel mixture, causing the engine to struggle in maintaining a stable RPM.

Subheading 3: Possible Causes of P1135 Code in Toyota Camry

Cause 1: Faulty Air/Fuel Ratio Sensor: The most common cause of the P1135 code is a malfunctioning air/fuel ratio sensor. Over time, these sensors can wear out or become contaminated, resulting in inaccurate readings and triggering the code.

Cause 2: Wiring Issues: Another possible cause is damaged or loose wiring connections related to the air/fuel ratio sensor. Corroded or broken wires can disrupt the flow of electrical current, leading to a malfunctioning sensor.

Cause 3: Engine Control Module (ECM) Failure: In some cases, the P1135 code can be triggered by a failure in the Engine Control Module. The ECM is responsible for monitoring and controlling various engine functions, including the air/fuel ratio sensor. If the ECM malfunctions, it may send incorrect signals to the sensor, causing the code to appear.

Subheading 4: How to Fix the P1135 Code in Toyota Camry

Solution 1: Replace the Air/Fuel Ratio Sensor: If the issue lies with a faulty sensor, replacing it with a new one is usually the best course of action. It is recommended to use OEM (Original Equipment Manufacturer) parts for optimal performance and compatibility.

Solution 2: Check and Repair Wiring: Inspect the wiring connected to the air/fuel ratio sensor for any signs of damage or loose connections. If any issues are found, repair or replace the affected wiring accordingly.

Solution 3: Test and Replace the ECM: If all else fails, it may be necessary to test the Engine Control Module for any faults. If a failure is detected, replacing the ECM may be required. However, this step should only be taken after ruling out other possible causes and consulting with a professional mechanic.
