P1153 Lexus Code - Air/Fuel Ratio Sensor Circuit Response Malfunction Bank 2 Sensor 1

Quick Answer

The Air-Fuel ratio (A/F) sensor varies its output voltage in proportion to the air-fuel ratio. Common causes include Faulty Air/Fuel Ratio Sensor Bank 2 Sensor 1, Air/Fuel Ratio Sensor Bank 2 Sensor 1 harness is open or shorted, Air/Fuel Ratio Sensor Bank 2 Sensor 1 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1153 Lexus Description

The Air-Fuel ratio (A/F) sensor varies its output voltage in proportion to the air-fuel ratio. Based on the output voltage, the Engine Control Module (ECM) determines if the air-fuel ratio is RICH or LEAN and adjusts the stoichiometric air-fuel ratio. The ECM also checks the fuel injection volume compensation value to check if the A/F sensor is deteriorating or not. A/F sensor response deterioration is determined by the ratio of the A/F sensor output voltage variation and fuel trim variation.

- Common symptoms include poor fuel economy, rough idling, hesitation during acceleration, and illuminated Check Engine Light.

2. What does the OBDII code P1153 in a Lexus indicate?

- This code indicates a malfunction in the air/fuel ratio sensor circuit for Bank 2 Sensor 1, which is usually located before the catalytic converter.

3. What are possible causes of the P1153 code in a Lexus?

- Possible causes include a faulty air/fuel ratio sensor, wiring issues in the sensor circuit, vacuum leaks, exhaust leaks, or a malfunctioning engine control module (ECM).

4. How can I diagnose the P1153 code in my Lexus?

- Diagnosis typically involves using an OBDII scanner to retrieve the code, inspecting the air/fuel ratio sensor and its wiring for damage, checking for vacuum or exhaust leaks, and testing the sensor's response.

5. Can I drive my Lexus with the P1153 code?

- It is not recommended to drive the vehicle with the P1153 code, as it can lead to poor engine performance and potential damage to the catalytic converter over time.
