The P0310 code is a generic powertrain code related to the ignition system or misfire. In this case, a misfire has been detected specifically in cylinder number 10.
Codes related to the P0310 include:
When an engine misfires, a lack of combustion has occurred. The engine control module (ECM) features a misfire detection monitor to detect an engine misfire and denote in which cylinder the misfire occurred. Using crankshaft and camshaft positions, as well as engine RPM, the ECM calculates necessary fuel delivery and ignition timing. To store a P0310 code, the ECM has specifically detected a misfire in cylinder number 10.
If the Check Engine Light illuminates fully and a P0310 code is stored, the ECM detected a misfire in cylinder number 10 that is severe enough to possibly damage the catalytic converter. Otherwise, the Check Engine Light may blink and turn off, meaning a misfire has been detected, but that the effects are not currently severe enough to damage the catalytic converter.
Several problems may cause a P0310 code including:
Symptoms of a P0310 code may include:
A warning or Check Engine Light may illuminate, blinking for a short period of time or staying on completely
The vehicle may not start immediately
The vehicle may idle rough
The engine may hesitate or shake during acceleration
A mechanic may use several methods to diagnose a P0310 trouble code, including:
Utilize an OBD-II scanner to check for a stored P0310 trouble code
Check fuel levels and pressure
Check that all filters and spark plugs are working properly
Visually inspect all wires and related electrical components for obvious signs of damage
Check ignition components for damage
Swap the coils, spark plugs, and spark plug wires and boots from cylinder 10 to another cylinder to determine if it’s faulty or damaged, by seeing if the misfire moves
Check exhaust condition to determine if rich or lean
Check for any vacuum leaks or damaged or defective vacuum hoses
Check for possible exhaust gas recirculation valve malfunctions
Check for damaged or defective fuel injectors
Check for clogging in the catalytic converter
Since several possible problems can cause a P0310 code, be sure to check all fuel and ignition systems for correct operation before moving on to other possible problems.
Typically, no symptoms are detected for a P0310 code, and the symptoms that may appear are minor, therefore this is not considered to be a serious code, but it is recommended that you have the vehicle diagnosed and repaired as soon as possible to prevent further problems.
Several repairs can fix a P0310 trouble code and include:
Repair or replace any damaged or faulty wires and related components
Ensure all ignition-related components are working correctly and replace or repair as needed, including spark plugs, coils, and distributor cap
Repair or replace any damaged or broken and leaking vacuum hoses
Repair or replace damaged or defective exhaust gas recirculation valves
Repair or replace damaged or defective fuel injectors
Clean and repair or replace a clogged catalytic converter
Clear all codes, test-drive the vehicle, and rescan to see if any codes reappear
Some manufacturers may have issued technical service bulletins (TSBs) related to the P0310 trouble code. It is recommended to always check for any associated or related bulletins before making any repairs.
