Engine/Transmission (1998.5 - 2002) Oil Pressure Sensor on 1999 Model 3500

[Big John]

I have been trying to find the oil pressure sensor on my engine. It does not appear to be where the local Dodge shop nor the local Diesel mechanic says it is. Any help??

drivers side directly below ecm which is mounted on the block under the fuel filter canister. by the way the sensor is discontinued from dodge and cummins but you can use a sensor from a qsm cummins motor part #4088390. this only works on 98. 5-2000 year motors that have not had the high idle/oil pressure reflash.

Thanks BBliss, I was able to locate it with your assistance. The sensor I have has 4088390 stamped on it but was sold under some other 10********AC number. I assume this one is right. I have not had the reflash.



Thanks again,

Big John

The 4088390 stamped on the sensor is the Cummins part number.

Mopar P/N 5012991AC

Thomas, you are correct. I was going from memory, and it isn't what it used to be.
