The C-15 Cat has intake valve actuators with an associated oil pressure sensor. Apparently failure of the oil pressure sensor is a common problem and results in the "check engine" light illuminating on the driver's panel.
By turning on the ignition, turning off the cruise control and depressing and holding the set or resume button of the cruise control the "check engine" light will flash. By counting the number of flashes a two digit fault code will be generated. For instance nine flashes brief pause five flashes = 95, the fault code for the intake valve actuator oil pressure voltage fault. The codes can be found listed in the Caterpillar Operation and Maintenance Manual or online.
Has a guru with a C-15 Cat run into this problem? Facing the engine the sensor is on the driver side at the top of the block behind an air conditioning compressor and ahead of the turbos. On ours well obscured up by surrounding equipment.
Did you replace with OEM or aftermarket part?
