DTC P050E: - COLD START ENGINE EXHAUST TEMPERATURE OUT OF RANGE

For Vehicles With an Idle Air Control (IAC) Valve 
Description:  The powertrain control module (PCM) attempts to control engine speed during the key on, engine running (KOER) self-test. The test fails when the desired RPM could not be reached or controlled during the self-test.
Possible Causes: 
  • IAC circuit open
  • VPWR to IAC solenoid open
  • B+ or VPWR to IAC solenoid open
  • Air inlet is plugged
  • IAC circuit shorted to PWR
  • Damaged IAC valve
Diagnostic Aids: 
For All others 
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.
