Detailed Diagnostic Information
Based on , with careful note of any ambiguities in code mapping, and supplemented by general, field-level diagnostic practice.
1) What P0152 is (code context)
- General context: P0152 is an OBD-II powertrain diagnostic trouble code (DTC) related to the oxygen (O2) sensor circuit. The OBD-II systems monitor oxygen sensor circuits to assess exhaust gas composition and catalyst efficiency, and they store DTCs when abnormal circuit behavior is detected. This is consistent with the OBD-II framework described in the Wikipedia OBD-II overview and the Powertrain Codes sections (the entries explain that DTCs monitor sensors and emissions-related parameters in the powertrain) - i.e., P0152 is a powertrain O2 sensor circuit issue (diagnostic trouble code under Powertrain Codes)).
- Specific mapping ambiguity: An Open Source OBD2 code definition entry lists (O2 sensor circuit - High voltage - sensor 1 bank). In plain English, that implies a high-voltage fault on the upstream O2 sensor in Bank 1. This illustrates that there can be ambiguity in which bank/sensor a given P015X code refers to across different sources or vehicle implementations; some vehicles label Bank 1 Sensor 1, others refer to Bank 2 Sensor 1 for P0152. Therefore, always verify the exact sensor location using the vehicle's wiring diagram or service information for your make/model

Consider professional help if:
- You are not comfortable performing the diagnosis yourself
- The issue requires specialized tools or equipment
- Initial repairs did not resolve the code
- Multiple codes are present simultaneously
- The vehicle is still under warranty
