What does P0192 mean and how does it affect my car?
P0192 means the fuel pressure sensor is sending a high voltage signal to the engine control unit, which can cause performance issues like stalling or reduced fuel efficiency. Over time, ignoring this issue can lead to more significant engine problems.
What are the most common causes of P0192 and how much does it cost to fix?
Common causes include a faulty fuel pressure sensor, damaged wiring, or a clogged fuel filter. Repair costs typically range from $50 to $300 depending on the root cause and required repairs.
Can I drive my car with P0192 or should I stop immediately?
It's advisable to avoid driving your car if you see the P0192 code. Continuing to drive may lead to engine performance issues or stalling, which can be dangerous.
How can I diagnose P0192 myself using GeekOBD APP?
Using the GeekOBD APP, you can scan the vehicle for codes, check freeze frame data for context, and monitor live data from the fuel pressure sensor. This helps you understand the issue better before seeking repairs.
What vehicles are most commonly affected by P0192?
Commonly affected vehicles include the 2010-2015 Ford Fusion, 2012-2016 Chevrolet Malibu, and 2013-2017 Honda Accord. Always check for any recalls or technical service bulletins (TSBs) related to your model.
How can I prevent P0192 from happening again?
Regular maintenance is key. This includes changing your fuel filter at recommended intervals and periodically inspecting wiring and connectors for damage or corrosion.
What is P0192?
The diagnostic trouble code P0192 indicates that the engine control module (ECM) has detected a high input voltage from the fuel pressure sensor. This sensor plays a crucial role in monitoring the fuel pressure in the system, which is vital for optimal engine performance and efficiency. When the ECM receives a signal that exceeds the manufacturer's specified range, it triggers the P0192 code. This can lead to various issues such as poor engine performance, reduced fuel efficiency, and even stalling. For many drivers, this code may be accompanied by the check engine light illuminating on the dashboard. Common vehicles affected by this code include the 2010-2015 Ford Fusion, 2012-2016 Chevrolet Malibu, and 2013-2017 Honda Accord. Ignoring this code can lead to serious engine issues over time, so it’s essential to address it promptly. Understanding this code helps you take the right steps to diagnose and repair the underlying problem, ensuring your vehicle runs smoothly and efficiently.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0192 is present:
- The check engine light is illuminated, often staying on constantly until the fault is resolved.
- You may experience engine hesitations or stalling during acceleration, making driving difficult and unsafe.
- Fuel economy may decrease by 10-15%, leading to more frequent visits to the gas station.
- You might notice rough idling or engine performance problems when the vehicle is under load.
- In severe cases, your vehicle may fail to start due to improper fuel pressure readings.
Possible Causes
Most common causes of P0192 (ordered by frequency):
- The most common cause is a faulty fuel pressure sensor, which occurs in about 60% of cases. This can be due to wear and tear or exposure to high temperatures.
- Another cause could be damaged wiring or connectors leading to the sensor, which might account for 25% of cases. Corrosion or loose connections can disrupt the signal.
- A clogged fuel filter can also lead to incorrect readings, preventing the sensor from getting a proper fuel pressure signal. Regular maintenance can help prevent this issue.
- Less commonly, a malfunctioning ECM can misinterpret the sensor's readings, leading to false codes and confusion in diagnostics.
- In rare cases, a fuel pump failure may cause abnormal pressure readings, although this is less frequent.

Diagnostic Steps
Professional P0192 Diagnosis Process
Follow these systematic steps to accurately diagnose P0192. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion (5-10 minutes)
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion (5-10 minutes). Look for frayed wires around the fuel pressure sensor.
Step 2: Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes)
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes). This helps establish if other codes are present.
Step 3: Step 3: Component testing - Use a multimeter to check the voltage and ground signals at the fuel pressure sensor (20-30 minutes)
Step 3: Component testing - Use a multimeter to check the voltage and ground signals at the fuel pressure sensor (20-30 minutes). Ensure the readings fall within specifications.
Step 4: Step 4: System function test - After making repairs, verify proper operation of the fuel pressure sensor and clear codes using the GeekOBD APP (10-15 minutes)
