This code means that the car's computer thinks the fuel pump has been turned off suddenly, like when the car is in a crash. It's a safety feature to stop fuel from leaking.
The P1244 code is triggered when the vehicle's computer detects an unexpected shutdown of the fuel pump, which is often linked to a safety mechanism designed to prevent fuel leakage during accidents.
P1244 is an OBD-II code indicating that the Powertrain Control Module (PCM) has detected an emergency cut-off signal from the fuel pump circuit. This is typically initiated by the vehicle's safety systems, such as the inertia switch or crash sensor, which are designed to cut power to the fuel pump in the event of a collision to prevent fuel leakage.
• Engine will not start
• Engine stalls unexpectedly
• Fuel pump not operating
• Accidental triggering of the inertia switch
• Faulty fuel pump relay
• Damaged wiring or connectors in the fuel pump circuit
PCM: Powertrain Control Module, the computer that controls the engine and transmission.
Inertia Switch: A safety device that cuts off the fuel pump in the event of a collision.
• Check for any collision damage that might have triggered the inertia switch.
• Inspect the inertia switch and reset it if necessary.
• Test the fuel pump relay and related wiring for faults.
• Reset the inertia switch if it has been triggered.
• Replace faulty fuel pump relay.
• Repair or replace damaged wiring or connectors.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford Focus
• Ford Fiesta
• Mazda 3
• Regularly inspect fuel pump and related components.
• Avoid rough driving that might trigger the inertia switch.
• Ensure proper maintenance of vehicle safety systems.
Safety System Issue
• If the vehicle won't start, check the inertia switch.
• Consult a professional if the problem persists after resetting the switch.
Check with the vehicle manufacturer; some components may be covered under warranty if the vehicle is relatively new.
The P1244 code is more common in vehicles equipped with inertia switches, particularly in models from the late 1990s to early 2000s.
High – This code indicates a potential safety issue and should be addressed immediately.
Driving with a malfunctioning fuel pump cut-off system can be dangerous. Ensure repairs are conducted by a qualified technician.
• Vehicle stationary
• Ensure no recent collisions or impacts
The inertia switch is typically located in the trunk or near the passenger footwell, depending on the vehicle model.
Q: What is an inertia switch?
A: An inertia switch is a safety device that cuts off the fuel pump in the event of a collision to prevent fuel leaks.
Q: Can I drive with the P1244 code?
A: It's not advisable to drive with this code active, as it indicates a potential issue with the fuel pump cut-off system.
