Code definition P0310
Code P0310 is a general driveline code related to the ignition system or misfire. In this case, the ignition failure was specifically identified on cylinder # 10.
Codes related to P0310 include:
- P0300: A random / multiple misfire has been detected on one cylinder.
- P0301: Misfire detected in cylinder 1
- P0302: Cylinder 2 mismatch detected
- P0303: Cylinder 3 fire break detection
- P0304: Cylinder 4 misfire detected
- P0305: Cylinder 5 misfire detected
- P0306: Cylinder 6 misfire detected
- P0307: Cylinder 7 misfiring detected
- P0308: Cylinder 8 misfiring detected
- P0309: Cylinder 9 misfiring detected
- P0311: Cylinder 11 misfire detected
- P0312: Cylinder 12 misfire detected
- P0314: Single cylinder malfunction (cylinder not specified)
What does the code P0310 mean
If the engine is misfired, the misfire is due to misfire. The engine control module (ECM) has an interruption-of-fire sensor that detects an interruption of fire in the engine and indicates in which cylinder the interruption has occurred. Based on the crankshaft and camshaft positions as well as the engine speed, the ECM calculates the required fuel supply and ignition timing. To store code P0310, the ECM has specifically detected a cylinder number 10 ignition failure.
If the Check Engine light is at full range and the code P0310 is recorded, the ECM has detected a cylinder number 10 ignition failure that is so serious that it may damage the catalytic converter. If not, the Check Engine light may flash, indicating that a misfire has been detected but the effects are not severe enough to damage the catalytic converter.
What causes the code P0310?
Several problems can be caused by the P0310 code, including:
- No fuel or poor fuel quality.
- Low fuel pressure
- Damaged or defective spark plugs, wires, or covers
- Broken or defective oxygen sensor
- Damaged or faulty fuel injector
- Leakage in the exhaust gas recirculation (EGR) valve
- Restricted EGR ports
- Malfunction of the EGR system
- Problems with the timing of the vehicle
- Damaged or defective ignition coils or wiring
- Damaged or defective ignition module or wiring
- Damaged or faulty ignition system sensors
- Evaporation of fuel vapors in the engine
- Clogged catalytic converter
What are the symptoms of the P0310 code?
Symptoms of the P0310 code may include:
- The warning light or Check Engine light may turn on for a short period of time or remain on all the time.
- The vehicle may not start immediately
- The vehicle may be idling
- The engine may jitter or jitter when accelerating.
How can a mechanic diagnose the P0310 code?
- A mechanic can use several methods to diagnose fault code P0310, including:
- Using the OBD-II scanner to search for the stored trouble code P0310.
- Checking fuel level and pressure
- Check that all filters and spark plugs are functioning properly
- Visually inspect all wiring and associated electrical components for visible signs of damage.
- Check ignition components for damage
- Swap coils, spark plugs and spark plug leads and boots from cylinder 10 with another cylinder to determine if it is faulty or damaged by checking for misfire displacement.
- Check the state of your exhalation to determine if it’s rich or thin.
- Check for vacuum leaks or damaged or defective vacuum hoses
- Check for possible malfunction of the exhaust gas recirculation valve.
- Inspect the fuel injectors for damage or defect
- Check that the catalytic converter is not clogged.
The most common errors when diagnosing the P0310 code
As several possible problems can be caused by the P0310 code, make sure all fuel and ignition systems are working properly before you go on to other possible problems.
How serious is the P0310 code?
Normally no symptoms are detected for the P0310 code and any symptoms that may appear are minor so this is not considered a serious code but it is recommended that the vehicle be diagnosed and repaired as soon as possible to avoid serious problems.
What repairs can fix fault code P0310?
Several repairs can fix the fault code P0310 and include:
- Repair or replacement of any damaged or defective cables and related components.
- Make sure all ignition-related components are working properly and replace or repair as necessary, including spark plugs, coils, and distributor cap.
- Repair or replace any damaged or cracked or 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 clogged catalytic converter
- Clear all codes, test the vehicle, and scan again to see if the codes reappear.
Additional notes for code P0310
Some manufacturers may have issued Technical Service Bulletins (TSBs) related to error code P0310. It is recommended that you always check the related or related newsletters before carrying out any repairs.
