Have you ever experienced a sudden jolt while driving your Ford, accompanied by a flashing “Check Engine” light? You might be wondering what’s going on, especially if you see the error code P0708 on your OBD2 reader. It’s a common issue, but don’t worry, we’re here to demystify it for you!
What is Ford OBD Code P0708?
The P0708 code is a diagnostic trouble code (DTC) specifically related to the transmission control system. It signifies a problem with the “Transmission Range Sensor” (TRS) circuit. This sensor plays a crucial role in your vehicle’s transmission, telling the computer which gear you’re in. It’s like a detective, reporting back to the brain (the computer) about what your transmission is up to.
Decoding the Mystery of Ford OBD Code P0708
Let’s break it down:
1. The Transmission Range Sensor (TRS): This sensor is responsible for monitoring the position of your transmission’s gear selector (think of it as the “P,” “R,” “N,” “D,” “S,” and “L” positions on your shifter). It sends this information to the transmission control module (TCM) – basically, the brain of your transmission.
2. The Error Message: When the TCM receives a faulty signal from the TRS, it throws the P0708 code. This code means that the TCM is unable to properly determine which gear your transmission is in, potentially causing shifting issues and other problems.
What Causes the P0708 Code?
There are a few common culprits behind this code, and understanding them can help you pinpoint the issue. Here are some possible scenarios:
1. A Faulty Transmission Range Sensor: This is often the leading cause of the P0708 code. Over time, the TRS can malfunction due to wear and tear, dirt, or even corrosion.
2. Wiring Problems: The TRS is connected to the TCM through a wiring harness. Damaged or loose wires can disrupt the signal flow, causing the code to appear.
3. Transmission Control Module (TCM) Malfunction: While less common, the TCM itself can malfunction, resulting in inaccurate readings or the inability to properly interpret the signals from the TRS.
4. Electrical Problems: Other electrical components, like the ignition switch or a short circuit in the wiring, can also disrupt the communication between the TRS and the TCM, leading to the P0708 code.
Fixing the Ford OBD Code P0708: A Step-by-Step Guide
Now that we understand the potential culprits, let’s tackle the problem head-on. Here’s a step-by-step approach to troubleshoot and fix the P0708 code:
1. Inspect the Transmission Range Sensor:
- Locate the TRS: First, you need to identify the location of the TRS. It’s usually located on the transmission itself, near the gear selector lever.
- Visual Inspection: Check for any visible damage, loose connections, or signs of corrosion.
- Clean the TRS: If you find any debris, dirt, or corrosion, clean it with a contact cleaner or a toothbrush.
2. Check the Wiring:
- Trace the wiring harness: Follow the wiring harness from the TRS to the TCM.
- Look for damaged wires: Inspect the wires for any cuts, abrasions, or loose connections.
- Test the wiring: Use a multimeter to test the continuity of the wiring harness.
3. Verify the Transmission Control Module:
- Consult a professional: If you suspect a TCM malfunction, it’s best to consult a qualified automotive technician for diagnosis and repair.
4. Other Electrical Components:
- Ignition Switch: Inspect the ignition switch for any signs of wear or damage.
- Short Circuits: Check for any potential short circuits in the wiring.
Frequently Asked Questions (FAQs)
1. “Can I drive my Ford with the P0708 code?” While you might be able to drive for a short distance, it’s crucial to address the problem as soon as possible. The P0708 code can indicate a serious issue with your transmission, and ignoring it could lead to more severe problems.
2. “How much does it cost to fix the P0708 code?” The cost of repair varies depending on the cause of the problem. A simple cleaning of the TRS might cost a few dollars, while a replacement TRS or TCM repair can be more expensive.
3. “Is the P0708 code a serious issue?” The P0708 code can indicate a serious problem with your transmission, and it’s best to address it promptly.
4. “Can I reset the P0708 code myself?” You can reset the code with an OBD2 scanner, but that won’t fix the underlying problem.
