This summary uses the existing diagnostic information shown in full below.
The car's computer is saying that the sensor which checks the fuel pressure in one part of the engine is not working properly. It's like when a thermometer is stuck and can't tell you the right temperature.
The fuel rail pressure sensor monitors the pressure of the fuel being delivered to the engine. If the sensor signal is stuck, it means the sensor is not sending the correct data to the engine control module.
P118E indicates that the signal from the fuel rail pressure sensor on Bank 2 is not changing as expected. This could mean the sensor is stuck at a certain value, not reflecting the actual pressure changes in the fuel rail.
• Check Engine Light is on
• Poor engine performance
• Reduced fuel efficiency
• Faulty fuel rail pressure sensor
• Wiring issues or poor connections
• Malfunctioning engine control module (ECM)
Fuel Rail: A component that delivers fuel to the engine's injectors.
ECM: Engine Control Module, the computer that controls engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors to the fuel rail pressure sensor.
• Test the fuel rail pressure sensor for proper operation.
• Replace the faulty fuel rail pressure sensor.
• Repair or replace damaged wiring/connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Chevrolet Silverado
• Ford F-150
• Dodge Ram 1500
• Regular maintenance checks
• Ensure quality fuel is used
• Inspect fuel system components periodically
Sensor Issue
• Drive cautiously until repaired.
• Avoid heavy acceleration to prevent further issues.
Check with the vehicle manufacturer for specific warranty coverage on the fuel system.
This code has been more common in vehicles with higher mileage or those that have experienced fuel contamination issues.
Moderate – Should be addressed soon to avoid potential engine performance issues.
Ignoring this issue could lead to increased emissions and potential safety risks.
• Engine at operating temperature
• Vehicle in a safe, stationary position
The fuel rail pressure sensor is typically located on the fuel rail, which is part of the engine's fuel delivery system.
Q: Can I drive with a P118E code?
A: It's possible to drive for a short period, but it's not recommended as it can lead to poor engine performance and increased emissions.
Q: How can I prevent this code from appearing?
A: Regular maintenance and using high-quality fuel can help prevent sensor issues.
