This summary uses the existing diagnostic information shown in full below.
This code means that the engine's computer is having trouble with the power that cylinder number 11 is making. It's like if one of the legs on an 11-legged chair isn't working right, making the chair wobble.
The engine control module (ECM) monitors the power output from each cylinder. If cylinder 11 is not contributing the expected amount of power, the ECM will trigger this code.
P0293 is set when the ECM detects that cylinder 11 is not contributing to the engine's power balance as expected. This could be due to issues with fuel delivery, ignition, or mechanical problems within the cylinder.
• Check Engine Light is on
• Rough engine idle
• Decreased engine performance
• Faulty fuel injector on cylinder 11
• Ignition system problems (e.g., spark plug or coil)
• Mechanical issues such as low compression
ECM: Engine Control Module, the computer that controls engine functions.
Compression: The pressure created inside the cylinder when the piston compresses the air-fuel mixture.
• Check for any other diagnostic trouble codes (DTCs)
• Inspect the spark plug and ignition coil for cylinder 11
• Perform a compression test on cylinder 11
• Replace faulty spark plug or ignition coil
• Repair or replace the fuel injector for cylinder 11
• Address any mechanical issues found during diagnosis
• OBD-II scanner
• Spark plug wrench
• Compression tester
$150 - $500 depending on the specific issue
Moderate
• Ford F-Series
• Chevrolet Silverado
• Dodge Ram
• Regular maintenance of ignition components
• Use high-quality fuel
• Routine engine inspections
Engine Performance
• Do not ignore the Check Engine Light
• Get a professional diagnosis if unsure
• Avoid driving the vehicle hard until repaired
Check with your vehicle manufacturer; powertrain warranties may cover certain repairs.
This code is common in vehicles with high mileage or poor maintenance history, often related to wear and tear on engine components.
Moderate – Addressing this code promptly can prevent further engine damage.
Ignoring engine performance issues can lead to safety hazards and legal issues if emissions are affected.
• Engine at operating temperature
• Vehicle driven under normal conditions
Cylinder 11 is typically located in the engine block, depending on the engine configuration.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to decreased engine performance and potential engine damage over time.
Q: Can I drive with a P0293 code?
A: It's best to have the issue diagnosed and repaired as soon as possible to avoid further damage.

Fitment Required · Vehicle-fitment part
Commonly relevant for misfire, ignition-efficiency, and some drivability-related repairs.
Misfire and ignition-related faults commonly involve spark plugs as part of the repair path.
Check the correct plug type, gap, and engine application for your vehicle.

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.
