What is P1153 : Engine Error code Causes Explained
This Guide covers the P1153 engine trouble code, which usually indicates a problem with bank 2 oxygen sensor 1. The sensor may be producing inaccurate values, compromising air-fuel mixture and engine performance.
How to Identify a DTCs Number
The DTC (Diagnostic Trouble Code) P1153 refers to an issue related to the air-fuel ratio sensor circuit in your engine, specifically in the oxygen sensor circuit.
Understand that the trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
The error code P1153 often occurs when the engine control module (ECM) detects an abnormal reading from the air-fuel ratio sensor.
Causes of P1153 Code:
- Faulty Oxygen Sensor:
Faulty oxygen sensor on bank 2, sensor 1, which is not properly switching between rich and lean conditions due to contamination or internal malfunction. - Fuel System Issues:
Problems with the fuel injectors, fuel pressure regulator, or fuel pump can lead to a consistently lean air/fuel mixture, causing the oxygen sensor to not switch adequately. - Exhaust Leaks:
Leaks in the exhaust system near the oxygen sensor can disrupt the air/fuel mixture. - Damaged Sensor Wiring:
Damaged or corroded wiring to the oxygen sensor can disrupt the signal sent to the ECU. - Engine Management Issues:
Faulty components in the engine management system like the mass airflow sensor or throttle body can also contribute to the code.
Risk Level of P1153 Error Code:
The P1153 engine error code refers to a problem with the fuel system, specifically the oxygen sensor located in the bank 2 sensor 1 of the engine.
The high-risk level appears as a warning to prevent further damage and to emphasize the importance of addressing the issue quickly

FAQ’s
What is the P1153 engine error code?
The P1153 code indicates a malfunction in the oxygen sensor circuit, often related to the sensor’s response time or the air-fuel mixture.
What causes the P1153 engine error code?
Common causes include a faulty oxygen sensor, damaged wiring, or issues with the fuel system like a clogged fuel injector or exhaust leaks.
What is the risk level of the P1153 error code?
The risk level of the P1153 error code is high. If unresolved, it can lead to poor fuel efficiency, engine misfires, and potential long-term damage to the catalytic converter.
