Check engine light reads code 1400.

1999 V6 Flex Fuel.

Already replaced EGR valve, light came back on with this code. Any idea whatI need to do?

Thanks,

Gary

 

Replace the DPFE sensor...

 

Can you elaborate onthe DPFE abbreviation and location / approx cost of the sensor?

Thanks,

Gary

 

DPFE stands for Differential Pressure Feedback EGR sensor.. You'll see the manifold tubes coming up from the left side of the engine/manifold.. There will be two short high heat silcone hoses attached between the tubes and the DPFE.. Here's a generic pic of what the DPFE looks like for identification
