The Peugeot 207, a popular compact car, like many modern vehicles, is equipped with an On-Board Diagnostics II (OBD2) system. This system is crucial for vehicle maintenance and repair, allowing mechanics and car owners to access valuable data about the car’s health and performance. Understanding the OBD2 connector in your Peugeot 207 is the first step towards effective vehicle diagnostics. This article will guide you through the Peugeot 207 OBD2 connector pinout, its compatibility, and how it facilitates vehicle diagnostics.
Understanding the OBD2 Connector in Your Peugeot 207
The OBD2 system is standardized across most modern cars, and the Peugeot 207 is no exception. The OBD2 port is typically located within the driver’s cabin, often under the dashboard, making it easily accessible. This standardized port is designed to interface with diagnostic scan tools, enabling communication with the vehicle’s electronic control units (ECUs). Through this connection, a wealth of information can be accessed, including diagnostic trouble codes (DTCs), live sensor data, and vehicle parameters.
Peugeot 207 OBD2 Connector Pinout: Decoding the Pins
The OBD2 connector is a 16-pin interface, and each pin is assigned a specific function. While some pins are standardized across all OBD2 compliant vehicles, understanding the pinout specific to Peugeot vehicles can be beneficial for advanced diagnostics and troubleshooting. Below are two common pinout configurations that might be relevant for your Peugeot 207, especially considering different production years and specific models.
Standard OBD2 Pinout for CAN-BUS Vehicles (Peugeot 2006 onwards):
This pinout is commonly found in Peugeot 207 models manufactured from 2006 onwards, which utilize the Controller Area Network (CAN-BUS) communication protocol.
| Pin Number | Pin Name | Description |
|---|---|---|
| 3 | CAN-H Diag | CAN-Bus High for Diagnostic Communication |
| 4 | Ground (GND) | Chassis Ground |
| 5 | Signal ground (GND) | Signal Ground |
| 6 | CAN-H Powertrain | CAN-Bus High for Powertrain (Engine-related) |
| 7 | ISO9141 K Line | K-Line for ISO 9141-2 and ISO 14230-4 Protocols |

It’s important to note that Peugeot vehicles manufactured prior to 2006 might utilize the VAN-Bus pinout system instead of CAN-BUS for diagnostic communication. While Peugeot 207 models are generally within the CAN-BUS era, verifying the specific pinout for your model year and engine type is always recommended.
OBD2 Compatibility and Protocols for Peugeot 207
Peugeot 207 models are generally OBD2 compliant, which means they adhere to the standardized OBD2 protocols for vehicle diagnostics. However, the specific protocol used can vary depending on the engine type and the year of manufacture. Common OBD2 protocols used in Peugeot 207 vehicles include:
- ISO 9141-2: An older protocol, often used in European vehicles.
- ISO 14230-4 (KWP2000): Keyword Protocol 2000, another protocol commonly found in European cars.
- CAN (CAN-BUS): Controller Area Network, the modern and most prevalent protocol in contemporary vehicles, including later Peugeot 207 models.
