P0403 Code

[Madmax]

I have the engine fault light on, not flashing just a steady light. The key dance tells me I have P1103, P0403 and p1685 codes. My mechanic said that his code reader was only showing P0402. Now I have checked the voltage on the pins that go to the EGR solenoid and this is only showing about 6 to 7 volts. Is this the correct voltage, have looked at stuff on you tube and they say 12 volts. But being a Chrysler who knows what voltage it should be. Any help will be appreciated.

It might be the case here that if the EGR is stuck in a certain position it will log that position up and notify the ECU. But is it the EGR at fault though ?

Well just went out and disconnected the power to the big solenoid and the engine management light has gone out. The code still shows when doing the key dance ,but at least it is now clear according to the dash board.

Egr solenoids hard to find [dealers dont have them] Mine had gone, last I was in USA I bought 5 from main Chrysler dealer

Many sensors and the like work with between 1v and 6v as the ECU/computors like low voltages..
