The P1258 is a comparative code. This code happens when your powertrain control module (PCM) looks at the sensor on the gas pedal and the sensor on the motor throttle, then compares the two, ensuring that they’re working together. If there’s a problem with one or both of the sensors, the PCM may trigger the P1258. This code definition is only common to Ford, Citroen, and Peugeot vehicles, although depending on your make and model, it may also appear for other vehicles.
More About the P1258 Code
P1258 is one of the codes that may have different definitions for different manufacturers. While “Pedal Correlation PDS1 and PDS2” is the common definition for Citroen, Peugeot, and Ford, it’s common to see the description being different for other manufacturers. Here are some common manufacturer-specific faults:
- Acura, Honda: VTEC System Malfunction
- Audi, Buick, Cadillac, Chevrolet, GMC, GM, Isuzu, Oldsmobile, Pontiac, Saab, Volkswagen: Engine Coolant Overtemperature Protection/Engine Overheating
It’s important to look at the definition of your P1258 code, not just the actual code itself. If you’re not using a Citroen, Peugeot, or Ford vehicle, then this code may indicate something different.

What Are the Symptoms of a P1258 Code?
The most common symptom of this code is simply that the check engine light will turn on. You may notice no other symptoms in drivability; if you do notice any drivability issues, they’ll usually be minor, such as a minor issue with a dead gas pedal that only occurs for a few seconds or the pedal not giving as much acceleration as you would expect.
What Are Some Causes of a P1258 Code?
The P1258 code will usually appear because the throttle sensor itself is having a problem, whether due to the fact that the throttle needs to be replaced, the sensors connecting the throttle to the powertrain control module (PCM) are broken or corroded, or you need to run a Pedal Relearning cycle, which allows the accelerator to reset.
How Serious Is the P1258 Code?
It depends on the symptoms that you’re having alongside this code. In some instances, the P1258 code isn’t very serious, while in some cases, it’s very urgent to fix the problem as soon as possible. Either way, due to the possibility that the P1258 code could create erratic problems with a dead gas pedal, most experts will suggest fixing it as soon as possible.
Can I Still Drive with a P1258 Code?
Most of the time, the only problem with the P1258 code is that you’ll have the check engine light illuminated, which means it’s usually safe to drive to your local repair shop and get help from an expert. If your check engine light is on, then an expert will not suggest that you keep driving, however. It’s hard to know exactly the problems you’re experiencing within your car, and this light should push you to get help from an expert.
How Easy Is It to Diagnose a P1258 Code?
This diagnosis process is typically pretty straightforward; a P1258 code usually only indicates a problem within the throttle sensor of the car, and that means you only have to check for issues within your throttle sensor. However, it’s also possible that you’re not just dealing with a P1258 code but also with other codes that indicate other problems. If a simple pedal relearning doesn’t fix the code, or you’re experiencing multiple different codes within your car, then it’s best to talk to an expert instead of trying to figure it out yourself.
How Difficult Is It to Inspect a P1258 Code?
Many beginners can effectively inspect a P1258 code, as issues with the connections may be obvious. If you notice obviously corroded or disconnected wires, then they’ll usually be apparent to everyone, including people without much knowledge of car handling. However, if you have more than one code or there’s no obvious issue with the throttle connections, you may need an expert’s advice.
