Egr wasn't all that dirty......

[SHOfun 93]

Well I pulled the intake and cleaned the IAB/EGR area and was gonna go at it to clean well with a hanger and stuff..and it wasnt really that dirty. Anybody else have any idea what is causing my code of low EGR voltage to come on? Thanks.

First Jeremy, Did you clear the codes? If not, try that first. Next, check to see if the hoses are connected to the DPFE and the sensor wire's are connected. If that does not fix it then you want to look at the tube that goes down to the rear exhaust bank to make sure there are no holes in it (it tends to break right at the manifold. If that is ok, then you need to replace the EGR & the DPFE sensor. How many miles are on your SHO? Mine went out at about 100Kmi.

Well, since i was already helping you in your other post I will continue if you'd like.

Have you Measure voltage between VREF circuit and SIG RTN circuit at PFE/DPFE sensor vehicle harness connector?
With the key on engine off,

If the voltage is between 4.0 and 6.0volts, Then you need to replace the PFE/DPFE sensor.

Thanks for the pic...I have the intake completely off and throttle body off and the stuff all cleaned out. One last question, where do I put the tester to check the voltage? Thanks bunches guys..

Well I still need to know where I need to put connectors to check the voltage on the sensors. HELP! thanks

With the connector plugged in at its normal connection, you need to tap into the the connector. Ex. paper clips work fine. Usually the 2 outer wires are the voltage Ref. and voltage RTN.

Measure between those two.
