P0308 Code (Symptoms, Causes, and How to Fix)
A random engine shudder or misfire is alarming but modern vehicles are quite good at recording misfire events, even cylinder-specific. P0308 indicates that cylinder #8 is misfiring. Here we go…

Engine sensors prevent catastrophic damage, but trigger false alarms if they malfunction. Code P0520 indicates the oil pressure sensor circuit has failed. This article covers common causes of a P0520…
Emissions systems rely on accurate sensor data, but failure can occur over time. Code P0452 indicates low voltage at the evaporative emissions pressure sensor. This guide will explain common causes…
Evaporative emissions systems rely on the fuel tank pressure sensor. Though this sensor has been re-engineered on multiple levels to last a long time, failure can eventually occur. Learn the…
While transmissions are engineered to be relatively hearty by design, they are not immune to the occasional mechanical or electrical issue. A transmission warning light means immediate action is required…
A check engine light requires investigation but doesn’t mean instant repair is needed. Code P0307 specifically indicates the #7 cylinder is misfiring. Read on to learn the common causes of…
Oxygen sensors are key for performance and emissions, but can (and will) fail over time. Code P0139 indicates an issue with one of your vehicle’s O2 sensors. Let’s go over…
Oil and coolant mixing in a vehicle engine creates a milky, off-colored sludge that is difficult to remove. This fluid contamination indicates a mechanical failure allowing the liquids to intermingle….
Modern vehicles rely on oxygen sensors to monitor exhaust gases and adjust fuel trim for efficiency. But O2 sensors fail over time, triggering check engine lights and lean/rich running conditions….
A car’s RPM dipping up and down spells trouble. As drivers, we know our vehicles’ rhythms so deeply that the slightest hiccup raises alarms. Fluctuating engine speeds while cruising or…
Diagnostic trouble code P0234 indicates excess boost pressure in the intake of turbocharged or supercharged engines. This forced induction-specific code points to an over-pressurization issue that can lead to severe…
Engine misfires can cause hesitation and performance issues. Fortunately, modern vehicles log misfire details, like cylinder and timing. Code P0316 indicates a misfire on startup, within the first seconds of…
