Code P050B Toyota Description
The Diagnostic Trouble Code (DTC) is designed to monitor the ignition timing at a cold start. When the engine is started at an engine coolant temperature of below 50°C (122°F), the Engine Control Module (ECM) checks the ignition timing during engine idling. If the ignition timing advances beyond the specified level within 10 seconds, the ECM interprets this as a malfunction. The MIL is illuminated, and a DTC is stored when the malfunction is detected in consecutive driving cycles (2 trip detection logic).
