check the egr temp sensor is not unplugged or shorted high?.

I have also seen that code when the egr cooler was not doing its job properly. - Especially true of After-market egr coolers. They are notorious for not cooling the exhaust gas properly, and it can lead to a destroyed enigne.

I took off the egr valve today
These are picture of valve opening
It seems exhaust gas never passed the valve but there are signs of coolant
Even at the bottom of valve was some fluid
And solid matter like mud or something like that


RE: EGR fault code - tree98 - 02-26-2019

Doesn't look like exhaust has been going through that for quite a while. You sure this engine hasn't been demandated ?


RE: EGR fault code - Rawze - 02-26-2019

looks like no egr gas has gone through that thing in a long time. Also, it is normal to have mud in it if that is the case,.. condensation (not coolant) likes to build up like mad in that circuit if it has been blocked off.
