P2B95

Cold Start Injection Pulse Performance

Moderate severity

What it means

During cold start, the ECM detects that the overall injection pulse performance does not match the calibrated cold-start strategy. Combustion stability is reduced during warm-up.

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.

Most likely causes

  • Injectors aged - flow drift across cylinders

    high

    One of the most commonly reported causes for this code — check this first.

  • Fuel rail pressure drifts during pulse

    medium

    A plausible cause — test and verify before replacing parts.
