P200E - CATALYST SYSTEM OVER TEMPERATURE (BANK 1)
| Description: | The PCM monitors the exhaust gas temperature bank 1, sensor 2 (EGT12) and exhaust gas temperature bank 1, sensor 3 (EGT13) for an over temperature concern. If the EGT12 sensor temperature is greater than 830°C (1, 526°F) or the EGT13 sensor temperature is greater then 950°C (1, 742°F), the DTC is set. This DTC causes the PCM to immediately illuminate the malfunction indicator lamp (MIL) and enter a torque reduction failure mode effects management (FMEM), which may result in engine shutdown. Once the engine is shut down, the PCM prevents the engine from restarting for 1 hour. If the EGT13 sensor is not working, the engine will not start. | ||

| Diagnostic Aids: | This DTC is an informational DTC and may be set in combination with a number of other DTCs which are causing the FMEM. Diagnose other DTCs first. Check the EGT12 and EGT13 PIDs. If no other DTCs are present, the system is operating correctly at this time. Advise the customer of the conditions that may cause this DTC. | ||
