Many of our customers have informed us about problems they were having with leak-through failures of the OEM oil pressure sensors on the transit bus diesel engines. The separate diaphragm and seal on the OEM sensor can be compromised and allow oil to migrate down the harness to the ECM. If the oil infiltrates the ECM, the resulting failure can be very costly with the repair of one bus going north of $10,000 when all is said and done. Even if the failure does not involve the ECM, the failing sensors will cause the bus engine to derate or shut down depending on the reported pressure and RPMs. This results in the bus being towed into the garage to have the sensor changed out and sending out another bus to pick up the passengers who have been seriously inconvenienced.
Our US Made sensor features a stainless steel welded chamber design which cannot suffer the leak-through failures of the OEM device. The OEM sensor is not only prone to internal leaks but external leaks as well, due to the molded plastic receptacle being epoxied to the sensor body. Our design features a separate pigtail which is plug and play with the OEM harness plug but will not be subject to external leaking. Our VT280100-OPS replaces the most common OEM diesel oil pressure sensor being used over the last 15 years. We also offer a unit for CNG engines (VT280100-CNG) and one for the latest L9 diesel engine(VT280100-OPS2).
