Question about 1999 Dodge Ram
Getting this code. manual says it is low voltage to the oil pressure sending unit. How do I repair this? Does this mean that the sensor is bad?
I've just changed the camshaft sensor 2 days ago for a code that came up for that could this be related issues?
There are a few possible items but none really common right out the gate. The oil pressure switch will be the most likely problem. The other issues would be either wiring or PCM (engine computer). There is a test you can run but it requires a good scanner that can read the oil pressure state. The oil pressure guage is not connected directly to the oil pressure switch. The switch is a simple on and off switch. Once there is enough oil pressure the switch closes. The actual gauge in the cluster is operated by software based on engine rpm, temp and the oil pressure switch. Its an educated guess of the oil pressure. If you dont have the scanner than the first step I would recommend is replacing the oil pressure switch and disconnecting the battery and clearing the code.
