Easy one-page printout for the garage or repair shop
This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the part of the car that helps make the spark in cylinder 8. It's like when a flashlight doesn't work because the battery contacts are dirty or loose.
The code indicates that the ignition coil for cylinder 8 has a resistance or impedance that is higher than expected, which can affect the spark needed for combustion.
The P3310 code is triggered when the Engine Control Module (ECM) detects an abnormal resistance or high impedance in the ignition coil circuit of cylinder 8. This can prevent the coil from generating the proper spark needed for the cylinder to fire correctly.
• Engine misfire
• Rough idle
• Check Engine Light illuminated
• Faulty ignition coil in cylinder 8
• Corroded or damaged coil connectors
• Wiring issues in the ignition coil circuit
Ignition Coil: A component that transforms the battery's voltage to a higher voltage needed to create a spark in the spark plugs.
Impedance: The resistance of an electrical circuit or component to alternating current, measured in ohms.
• Use an OBD-II scanner to confirm the code.
• Inspect the ignition coil and its connections for damage or corrosion.
• Measure the resistance of the ignition coil and compare it to specifications.
• Replace the faulty ignition coil.
• Clean and secure the ignition coil connectors.
• Repair or replace damaged wiring in the ignition coil circuit.
• OBD-II scanner
• Multimeter
• Socket set
$100 - $300
Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regularly inspect ignition coils and connectors.
• Keep engine components clean and free from corrosion.
• Perform routine maintenance checks.
Engine Performance
• If you notice a misfire, have the vehicle checked promptly.
• Avoid driving with a persistent Check Engine Light to prevent further damage.
Check with the vehicle manufacturer for specific warranty coverage on ignition components.
Ignition coil issues have been common in vehicles with high mileage or those exposed to harsh conditions.
Moderate – It should be addressed soon to avoid engine performance issues.
Driving with an engine misfire can lead to increased emissions and potential engine damage.
• Engine at operating temperature
• Vehicle in park or neutral
The ignition coil for cylinder 8 is typically located on the engine block, near the eighth cylinder.
Q: Can I drive with a P3310 code?
A: It's not recommended to drive for extended periods with this code, as it can lead to engine damage.
Q: How can I prevent ignition coil issues?
A: Regular maintenance and keeping the engine clean can help prevent issues with ignition coils.

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.
