Code result
P2B08
Cold Start Cylinder 1 Injection Pulse Performance
Moderate severity
What it means
During cold start, the ECM detects that the injection pulse on cylinder 1 does not produce the expected combustion result. Cold-start specific pulse calibration deviates from learned values.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
