DTC P050E: Cold Start Engine Exhaust Temperature Out Of Range

WARNING: This page is about a different variant/trim than selected.

P050E - COLD START ENGINE EXHAUST TEMPERATURE OUT OF RANGE

Description:	The powertrain control module (PCM) calculates the actual catalyst warm up temperature during a cold start. The PCM then compares the actual temperature to the expected catalyst temperature model. The difference between the actual and expected temperatures is a ratio. When this ratio exceeds the calibrated value this DTC is set and the malfunction indicator lamp (MIL) illuminates.
Possible Causes:	Intake air restriction Exhaust restriction Engine mechanical concern Damaged or sludged electronic throttle body (ETB) Vacuum leaks Damaged PCM
Diagnostic Aids:	This DTC is informational only and it may be accompanied by other DTCs. Diagnose other DTCs first. If other DTCs are not present inspect the intake air system for air restrictions, vacuum leaks, and damage. If no concerns are present, clear the DTC and carry out the key ON, engine running (KOER) self-test.
