What does code P2B96 mean?

Q: What does code P2B96 mean?

Injection Pulse Performance. P2B96 indicates that the powertrain control module (PCM) has detected an abnormal condition in the injection pulse performance for a fuel injector circuit, meaning the commanded injector on-time does not match the expected response from the engine. The PCM monitors injector pulse width and compares it to feedback from the oxygen sensor and crankshaft position sensor to identify a deviation that exceeds calibrated limits.
