Q: What does code P26FF mean?

Auto Configuration Throttle Input Not Present Bank 2. P26FF means the engine control module (ECM) has lost the learned auto-configuration data for the bank 2 throttle input circuit, so it cannot verify that the throttle position signal from that bank is present and plausible. The ECM detects this when the ignition is cycled and the expected throttle input voltage or learned range for bank 2 is missing from its memory or fails the self-configuration check.
