This summary uses the existing diagnostic information shown in full below.
This means that the engine's computer has detected that the pressure in cylinder number 11 is lower than it should be. Imagine a balloon that isn't filled up enough with air.
The engine control module (ECM) monitors the pressure in each cylinder to ensure proper combustion. If the pressure in cylinder 11 is too low, it triggers this code.
P2361 indicates that the pressure sensor or related component has detected a lower than expected pressure in cylinder 11. This could be due to a variety of mechanical or sensor-related issues affecting the combustion process.
• Engine misfire
• Reduced engine performance
• Increased fuel consumption
• Check engine light on
• Faulty pressure sensor
• Leaking head gasket
• Worn piston rings
• Valve issues
• Faulty ECM
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
Compression Test: A test to measure the pressure in an engine's cylinders
• Connect an OBD-II scanner to check for additional codes.
• Inspect the pressure sensor and its wiring for damage.
• Perform a compression test on cylinder 11.
• Check for leaks in the head gasket.
• Replace or repair the pressure sensor.
• Fix any leaks in the head gasket.
• Replace worn piston rings.
• Repair or replace faulty valves.
• OBD-II scanner
• Compression tester
• Wrench set
• Multimeter
$150 - $1000 depending on the cause
Moderate
• Ford F-150

Engine Performance
• Avoid driving with a misfiring engine.
• Get the issue diagnosed as soon as possible.
Check with your vehicle manufacturer for warranty coverage on engine components.
This code has been associated with issues in larger engines with more than 8 cylinders, often due to mechanical wear.
High – Can lead to severe engine damage if not addressed.
Driving with a misfiring engine can be dangerous and may violate emissions regulations.
• Engine at operating temperature
• Vehicle in park or neutral
Cylinder 11 is located in the engine block, typically on the far end of the cylinder bank.
Q: Can I drive with a P2361 code?
A: It's not recommended as it can cause further engine damage.
Q: How can I prevent this issue?
A: Regular maintenance and using quality fuel can help prevent pressure issues.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
