Misfire Codes P0301 To P0312: A Look At Common Causes
A flashing check engine light and a P0301 to P0312 diagnostic trouble code (DTC) is a surefire indication that one or more cylinders are misfiring. Occasional misfires may pass unnoticed, but a steady misfire is hard to miss. The engine usually feels rough, lacks power and uses more gas than usual. Sometimes a misfire may

Deciphering the Da-VIN-ci Code
Making heads or tails of the all-too-important 17-digit Vehicle Identification Number.
Component Connection: Emission Control — O2 Sensor Diagnostics
In recent years, the design of O2 sensors has changed. The ceramic thimble-shaped element in zirconia-type O2 sensors has been replaced by a flat strip ceramic “planar-”style sensor element.
Undercover: Managing Emissions — Diagnosing Catalytic Converter Concerns
Before a technician replaces a converter, they need to address the possible reasons for it failing in the first place.
Tech In Training – Monitoring Emission Efficiency with O2 Sensors
As modern OBD II technology marches on, its clear that the zirconia-based oxygen sensor now is being sold more as a basic repair part than as a preventive maintenance part, and it changes the way technicians diagnose and sell oxygen sensors. To illustrate the difference, understand that an oxygen sensor replacement used to be considered
Catalyst Efficiency Diagnostics
When making the tough decision on replacing a customers catalytic converter your diagnosis must be accurate.
ADAS False Activation Evolution
The logic behind most ADAS warnings or corrections is to examine the plausibility of the situation.
ADAS False Activation Evolution
Since 2006, advanced driver assistance systems (ADAS) have evolved from active cruise control to autonomous driving controls.
Diagnosing Misfires
What if there are no codes and a misfire is intermittent? This is where it gets complicated.
