Q: What does code P2B95 mean?

Cold Start Injection Pulse Performance. P2B95 indicates that the engine control module (ECM) has detected an abnormal cold-start injection pulse performance, meaning the fuel injector pulse width during a cold start did not match the expected value for the engine's temperature and operating conditions. The ECM monitors the cold-start fuel enrichment strategy and sets this code when the actual injection pulse deviates from the commanded pulse beyond a calibrated threshold.
