EGR Sensor D Circuit Range/Performance

Where it lives

For P2383, the part to look at first is the sensor named here.

Check these first

• An EGR sensor D reading outside its normal range
• Carbon buildup in the EGR passages skewing sensor D
• A stuck EGR valve not moving as commanded
• A worn EGR sensor D element

What to do next

1. Read EGR sensor D and commanded EGR position on a scan tool
2. Check the EGR valve for sticking or carbon
3. Test the EGR sensor D circuit for added resistance
4. Clean the EGR passages and valve
5. Replace EGR sensor D if the valve and passages test good
6. Clear the code and retest
