**Where is The Ford Probe OBD2 Location Found?**

Finding the Ford Probe OBD2 location is crucial for diagnosing car problems, and OBD2-SCANNER.EDU.VN provides the information you need. This article will guide you in locating the diagnostic port, understanding OBD-I and OBD-II systems, and using scan tools for effective car maintenance. Let’s explore the diagnostic port’s location and how OBD2 scanners can benefit your Ford Probe.

1. Understanding OBD-I and OBD-II Systems

What are the differences between OBD-I and OBD-II systems? OBD-I (On-Board Diagnostics I) and OBD-II (On-Board Diagnostics II) are automotive diagnostic systems, but they differ significantly in their standardization, capabilities, and data accessibility. OBD-I systems, which were implemented before 1996, are manufacturer-specific, meaning each carmaker could use different diagnostic connectors, trouble codes, and communication protocols. OBD-II, introduced in 1996, standardized these aspects across all makes and models sold in the United States, making it easier for technicians and car owners to diagnose and repair vehicle issues.

• Standardization: OBD-II provides a standardized diagnostic connector (SAE J1962), a set of standardized trouble codes (DTCs), and communication protocols (such as SAE J1850 PWM, SAE J1850 VPW, ISO 9141-2, ISO 14230-4, and CAN).
• Data Accessibility: OBD-II offers enhanced data access, including real-time data parameters (PIDs) like engine RPM, vehicle speed, and sensor readings, allowing for more precise diagnostics.
• Emission Monitoring: OBD-II systems are more focused on monitoring emissions-related components and systems to ensure compliance with environmental regulations.

2. Identifying The Diagnostic Port on a Ford Probe

Where can I find the diagnostic port on my Ford Probe? On Ford Probe models from 1993 to 1995, you won’t find a standard OBD2 port. These models typically use an OBD-I system. The diagnostic port is usually located in the front driver-side corner under the hood, between the fender and the battery.

The diagnostic port may be inside a diagnostic box, with a diagram underneath the cover showing the pin layout. The OBD-I system requires using a wire or paper clip to connect the GND (ground) pin to the TEN (test enable) pin to initiate the diagnostic process.

3. Step-by-Step Guide to Locating the OBD2 Port

Even though your Ford Probe might be using an older OBD-I system, let’s explore how to locate the OBD2 port in vehicles that do have them. Here’s a step-by-step guide:

1. Check Under the Dashboard: The most common location for the OBD2 port is under the dashboard on the driver’s side. Look for a 16-pin connector.
2. Consult the Vehicle’s Manual: If you can’t find the port immediately, refer to your Ford Probe’s manual. The manual will provide the exact location of the OBD2 port, accompanied by a diagram.
3. Check Behind the Ashtray or Coin Tray: In some Ford Probe models, the OBD2 port may be hidden behind the ashtray or a small coin tray. These can usually be easily removed to access the port.
4. Inspect the Center Console: In rare cases, the OBD2 port may be located in the center console. Check inside the console or along the sides.

4. Using a Scan Tool with Your Ford Probe

How do I use a scan tool with my Ford Probe? For 1993-1995 Ford Probe models with an OBD-I system, the process involves using a scan tool compatible with OBD-I or manually retrieving codes. Here’s how:

1. Manual Code Retrieval:

   • Locate the diagnostic port (usually in the front driver-side corner under the hood).
   • Use a wire or paper clip to connect the GND pin to the TEN pin on the diagnostic connection.
   • Turn the ignition to the ON position without starting the car.
   • Observe the check engine light, which will blink out the trouble codes. Long pulses indicate the first digit, and short pulses indicate the second digit.

2. Using an OBD-I Scan Tool:

   • Connect the OBD-I scan tool to the diagnostic port.
   • Turn the ignition to the ON position without starting the car.
   • Follow the scan tool’s instructions to read the trouble codes.

3. Interpreting the Codes:

   • Refer to a Ford Probe OBD-I trouble code list to understand the meaning of each code. For example, code 12 might indicate a Throttle Position (TP) Sensor issue.
   • Diagnose the issue based on the code and perform the necessary repairs.

4. Clearing the Codes:

   • To clear the codes, disconnect the car battery for at least 5 minutes. This will reset the Keep Alive Memory (KAM).
   • After resetting, start the car and let it idle for 10-15 minutes to allow the PCM to relearn the engine’s idle characteristics.
   • Drive the car normally for 15-20 miles to allow the PCM to relearn your driving habits.
