If flow is excessive I tried fixing for a sticking egr valve. I vacuum it up and tap the valve a little with a screwdriver handle. I also think it may be the Thermo sensor(see in pics). I have another thermo sensor from junkyard. What are the values I test for on the thermo sensor? What other causes of this problem can you think of? There is no valve position sensor as you can see. I believe the thermo sensor is the only trigger for the ECM to say the flow is too cold or excessive? I am not sure on the function read by ECM can you clarify please? Thanks
have the same problem?
