P0310 Code Definition

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:

What the P0310 Code Means

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.

What Causes the P0310 Code?

Several problems may cause a P0310 code including:

  • No fuel or low fuel quality
  • Low fuel pressure
  • A damaged or faulty spark plugs, wires, or boots
  • Damaged or defective oxygen sensor
  • Damaged or defective fuel injector
  • Leaking exhaust gas recirculation (EGR) valve
  • Restricted EGR ports
  • Complete EGR system malfunction
  • Vehicle timing issues
  • Damaged or defective ignition coils and wiring
  • Damaged or defective ignition module or wiring
  • Damaged or defective ignition system sensors
  • Fuel vapors evaporating into engine

  • 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

How Does a Mechanic Diagnose the P0310 Code?

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

Common Mistakes when Diagnosing the P0310 Code

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.

How Serious is the P0310 Code?

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.

What Repairs can Fix the P0310 Code?

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
