steeler Posted April 26, 2018 Share Posted April 26, 2018 Hey guys I'm getting a drv solenoid fault when I try a service regen. It will throw the code after only about 5 seconds after it starts the regen. It has a new drv solenoid and air line. I've removed the valve by the turbo and it functions perfect with the test on vcads. The fault is 128 ppid330 fmi7. Can anyone give me a suggestion?

turckster Posted April 28, 2018 Share Posted April 28, 2018 Make sure you have good air psi to the valve. Check and remove the eecu connectors to see if there is oil contamination. If there is the engine harness needs to be replaced along with the oil psi sensor and oil level sensor. A temp fix is to clean out the oil with electrical contact cleaner but the oil will wick right back----if oil contamination is an issue. Also, check the valve electrical contacts to make sure they are ok.

steeler Posted May 3, 2018 Author Share Posted May 3, 2018 Problem solved, I think. Ended up unplugging the boost sensor and it went ahead and did it's thing. Plugged it back in and its working perfect now. The boost reading was a little wacky, but now it's fine. Must've had a bad connection there. Thanks Turckster. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/53222-drv-solenoidregen-issue/#findComment-398124 Share on other sites More sharing options...
