What is P1150 : Engine Error code Causes Explained
The P1150 engine trouble number usually implies an air-fuel ratio or oxygen sensor malfunction. This article covers its causes, symptoms, and treatments to help you identify and treat it.
How to Identify a DTCs Number
The engine error code P1150 is typically related to fuel and air metering issues, often indicating an issue with the air-fuel ratio sensor, oxygen sensor, or fuel delivery system. To identify a DTC (Diagnostic Trouble Code) number like P1150, you need an OBD-II scanner.
Understand, this 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.
By connecting the scanner to the vehicle’s diagnostic port, usually located under the dashboard, you can retrieve stored codes from the ECM.
