The 2013 Ford Focus, a popular choice for its fuel efficiency and sleek design, has unfortunately been known to experience its share of car computer problems. This guide delves into the common issues, diagnostic procedures, and solutions for 2013 Ford Focus car computer problems, offering valuable insights for owners, mechanics, and automotive technicians alike.
Understanding Your 2013 Ford Focus Car Computer
The car computer, also known as the Powertrain Control Module (PCM), is the brain of your Ford Focus. It controls various systems, from fuel injection and ignition timing to transmission shifting and emissions control. A malfunctioning PCM can lead to a myriad of problems, impacting drivability, fuel economy, and overall performance.
Common 2013 Ford Focus Car Computer Problems
Some frequent car computer problems reported by 2013 Ford Focus owners include:
- Erratic Shifting: The transmission may shift harshly, slip, or refuse to shift altogether.
- Engine Misfires: The engine may misfire, resulting in rough idling, reduced power, and decreased fuel efficiency.
- Dashboard Warning Lights: The check engine light, transmission warning light, or other dashboard lights may illuminate.
- Stalling or Difficulty Starting: The vehicle may stall unexpectedly or experience difficulty starting.
- Reduced Fuel Economy: A faulty PCM can disrupt fuel injection and ignition timing, leading to poor fuel economy.

Diagnosing 2013 Ford Focus Car Computer Problems
Diagnosing car computer problems requires a systematic approach. Start by checking for any trouble codes using an OBD-II scanner. These codes provide valuable clues about the specific issue.
Using an OBD-II Scanner
An OBD-II scanner is a crucial tool for diagnosing car computer problems. Plug the scanner into the OBD-II port located under the dashboard on the driver’s side. The scanner will retrieve any stored trouble codes, which can be deciphered to pinpoint the problem area.
- Connect the OBD-II scanner to the port.
- Turn the ignition key to the “on” position without starting the engine.
- Follow the scanner’s instructions to retrieve trouble codes.
- Record the codes and research their meaning.

Beyond the OBD-II Scanner: Further Diagnostics
While the OBD-II scanner is a valuable starting point, further diagnostics may be required. This could involve checking wiring harnesses for damage, testing sensors, or inspecting the PCM itself for physical damage.
“A thorough diagnostic process is essential for accurately identifying the root cause of the problem,” advises John Miller, a seasoned automotive electrical engineer with over 20 years of experience. “Don’t jump to conclusions based solely on trouble codes. A comprehensive inspection is often necessary.”
Solving 2013 Ford Focus Car Computer Problems
Once you’ve diagnosed the problem, you can explore solutions. These could range from simple fixes like cleaning corroded connectors to more complex procedures like replacing the PCM.
Replacing the PCM
If the PCM is determined to be faulty, replacement is often the only solution. This involves programming the new PCM with the correct vehicle information.
