“A stitch in time saves nine,” they say. And when it comes to your car, it’s especially true. Ignoring a warning light like P0125 can lead to bigger, more expensive problems down the road. So, let’s dive into the world of your Honda Accord 2004 and understand this OBD code, its potential causes, and how to fix it.
What Does OBD Code P0125 Mean?
OBD code P0125 is a common issue in Honda Accords, particularly those from the 2004 model year. It stands for “Throttle Position Sensor/Switch A Circuit Malfunction.” Think of the Throttle Position Sensor (TPS) as the car’s “mouth,” telling the engine how much air to take in based on your gas pedal input.
Imagine your car as a hungry lion. The TPS is its mouth, which tells its stomach (the engine) how much food (air) to take in. If the TPS is broken, the lion gets confused and eats the wrong amount of food, leading to a variety of problems.
The Technical Details: What’s Going On With My Honda Accord?
A P0125 code pops up when the engine control unit (ECU) detects a problem with the electrical signal from the TPS. This can occur due to several reasons:
- TPS Sensor Failure: The most common culprit is a faulty TPS. This sensor can get dirty, wear out over time, or even suffer from internal damage.
- Wiring Issues: The wiring connecting the TPS to the ECU could be damaged, corroded, or have loose connections.
- ECU Fault: In rare cases, the ECU itself may be malfunctioning and misinterpreting the signal from the TPS.
P0125 Symptoms: Signs Your Honda Accord Needs Attention
You’ll likely notice some changes in your car’s behavior if it’s throwing a P0125 code:
- Rough Idle: The engine may idle unevenly, stuttering or shaking.
- Hesitation or Stalling: The car might hesitate when accelerating, or even stall entirely.
- Decreased Fuel Efficiency: Your gas mileage could take a hit.
- Check Engine Light: This is your car’s way of saying “something’s wrong!” and it’s always a good idea to get it checked out by a mechanic.
Troubleshooting P0125: Getting to the Root of the Problem
Now that we understand the problem, let’s figure out how to fix it. Here’s a step-by-step approach:
- Check the TPS Sensor: Use a digital multimeter to measure the voltage output of the TPS. Compare it to the manufacturer’s specifications to see if it’s within the acceptable range. If not, you likely need to replace the TPS.
- Inspect the Wiring: Check the wiring harness for any signs of damage, corrosion, or loose connections. Repair or replace any damaged wiring.
- Consider the ECU: While less common, it’s possible the ECU is faulty. If you’ve ruled out other issues, you may need to consult a mechanic to test the ECU.

Q1: How Much Does It Cost to Fix a P0125 Code?
The cost can vary based on the cause and the severity of the problem. A new TPS sensor typically costs between $50-$150, while labor costs can range from $50-$100.
Q2: Is It Safe to Drive With a P0125 Code?
It’s not recommended to drive for extended periods with a P0125 code. While your car might seem to run fine initially, ignoring the issue can lead to more serious problems, including engine damage.
Q3: Can I Reset the Check Engine Light Myself?
You can try resetting the code using an OBD scanner, but the problem will likely reappear if the underlying cause isn’t fixed.
