What Does Code P0316 Mean?
A P0316 troubleshooting code informs the driver or technician that the vehicle is experiencing a misfire within the first 1000 revolutions. Misfires can occur within the combustion chamber inside each cylinder, and they will cause the crankshaft to change speed ever so slightly. The vehicle’s computer, or Engine Control Module, will detect the change in the crankshaft or camshaft’s speed. This triggers the diagnostic troubleshooting code P0316.
What are the common causes of code P0316 ?
Once a P0316 has been detected, the goal is to find what is causing the engine to misfire. Misfires are typically a result of an ignition issue, fuel delivery problem, or an engine vacuum leak. It is also possible for a damaged crankshaft or camshaft position sensor to give you a false reading.
Start by finding any other related diagnostic troubleshooting codes related to the misfire. If the codes reveal an issue with a specific cylinder, start your inspection at that cylinder. Look into the ignition system (spark plugs, coils, distributor, wires) and the fuel system (injectors and fuel pressure).
If there are no other specific codes pertaining to the misfire, look for codes pertaining to the fuel delivery system, crankshaft position sensors, and the engine vacuum.
Over all, consider looking into the following components and systems:
• Ignition System: Including spark plugs, coils, distributor, spark plug wires
• Fuel Rail and Fuel Injectors
• Fuel Pump and Fuel Pressure
• Crankshaft Position Sensor and its wiring
• Engine Vacuum
What are the symptoms of code P0316 ?
Drivers typically notice a check engine light first and foremost. However, misfires can cause a range of symptoms noticeable while driving. These tend to include a lack of acceleration, excess engine noise, and/or rough idling. You may also notice the vehicle is using more fuel, as it is trying to compensate for the issue. The engine may feel sluggish and may not perform like you are used to.
What are common solutions to code P0316 ?
A P0316 code is most often triggered by an issue with the ignition system. Spark plugs, spark plug wires, coils, or the distributor (if equipped) are all capable of causing these issues and may need to be inspected first. If the misfire is isolated to one cylinder, you may only need to make repairs to those components. However, when one cylinder’s ignition system starts to have issues, the other may soon as well. If you are in a position to, you will want to consider replacing the entire ignition system depending on the extent of the issue.
If there are no issues found with the fuel or ignition systems, the crankshaft or camshaft position sensors, or the engine vacuum, take a look at the EVAP system and the Powertrain Control Module. These components can cause a misfire on start-up, but are among the least likely to do so.
