If the HPTuners is wired to read the sensor directly but the ECU is reporting zero pressure, the issue resides with the engine’s internal lubrication system or the ECU itself. Navigate to the inputs or gauge settings menu and ensure the correct channel is mapped to "Oil Pressure" and that the scaling parameters match the sender unit installed in your vehicle.
HP Tuners No Oil Pressure Troubleshoot Summary
You should also inspect the wiring integrity at the sensor connector itself, looking for corrosion, frayed wires, or pin-out damage that could interrupt the ground or reference voltage circuit required for accurate readings. You are looking for a stable reference voltage (usually 5 volts or 12 volts) and a varying resistance signal that corresponds to the physical movement of oil pressure.
Software Configuration and Channel Assignment It is possible the no reading is due to a configuration mismatch within the HPTuners software interface. Understanding the distinction between a software configuration issue and a physical hardware failure is the first step in resolving the problem and ensuring the safety of your high-performance engine.

Wiring Diagrams and Connector Inspection Consult the specific wiring diagram for your vehicle application and the HPTuners module. A short to ground or an open circuit will prevent the HPTuners from translating the resistance into a readable PSI value.
