2007 Dodge Ram 3500 SLT 5.9L MIL Lamp on VIN: 3D7MX39C47
P0642: sensor ref voltage low. Have heard that these wiring harness's and connectors for the engine are typically bad, just wondering if anyone else has had a problem like this? We have a customer coming to buy this asap. Would especially like to hear from Dodge diesel techs.
