Cummins diesel owners, this 2-pin oil pressure sensor is exactly what you need for your KTA19G engine! Direct replacement for OEM part number 3015237, this sensor monitors your engine's oil pressure and sends the reading to your gauge cluster or warning system. The two-pin design makes installation straightforward - just disconnect the old one and plug in the new. Critical for protecting your expensive diesel engine from low oil pressure damage that can cause serious mechanical failures. If your oil pressure gauge is reading inaccurately, fluctuating wildly, or you're getting warning lights, this sensor is likely the culprit. Much more affordable than buying from Cummins directly, but still delivers the reliable performance you need for heavy-duty applications. Don't risk engine damage from undetected low oil pressure - replace that questionable sensor with this direct-fit replacement. Quick installation means less downtime for your equipment or vehicle. Keep your Cummins running strong with proper oil pressure monitoring!
