Fault code information
1 trip MIL
3 drive cycle recovery
Readiness group – None
Freeze frame type – Comprehensive
Description of component(s)
The EGR gas flow temperature is measured after the EGR cooler.
Effect on the system:
* Corrects EGR gas flow calculation (the temperature is an indication of the gas density)
* Closes the EGR valve when the EGR temperature is too high
* Monitors EGR cooler performance
Location of component(s)

Set condition of fault code
The PCI ECU (D420) detects that EGR temperature sensor circuit output voltage is greater than 4.9 V.
Reset condition of fault code
This fault code will change to inactive immediately after the diagnostic runs and passes.
